FROM THE EDITOR<br />

THE WATER-ENERGY-<br />

FOOD NEXUS<br />

The circular economy in the water sector<br />

relies on the interconnected relationship<br />

between water, energy and food. At the heart<br />

of the UN <strong>2023</strong> Agenda, this nexus forms the<br />

core of its sustainable development goals.<br />

In this issue, experts give us a rundown<br />

on recovering energy, the climate impacts<br />

felt through water and upgraded water<br />

capabilities in Q1 of <strong>2023</strong>.<br />

South East <strong>Asia</strong>n countries are enhancing<br />

their water policymaking and technologies<br />

to secure the water-food-energy nexus. In<br />

Indonesia, smart water grid management is<br />

implemented to manage water, according<br />

to Bima Sakti Alterra (p. 40). Further, with<br />

Indonesia as a tourism destination, Bentley<br />

Systems’ digital monitoring software is<br />

utilised in Hutama Karya’s dam project for the<br />

development of the country’s infrastructure<br />

and economy, a ‘national strategic<br />

project for the acceleration of economic<br />

growth in Indonesia’ (p. 27). In Thailand,<br />

Xylem Analytics’ WTW smart sensors<br />

are implemented to monitor water quality<br />

and detect water contamination for early<br />

intervention (p. 20). All these innovations serve<br />

to stabilise the circular economy in this region.<br />

The world’s most populous countries, China<br />

and India, are finding ways to establish<br />

low-cost water systems. In a lithium iron<br />

phosphate cathode manufacturing facility<br />

in the Hubei province of China, circulating a<br />

closed water system helped to save high cost<br />

(p. 28). The winner of 2022 VinFuture Special<br />

Prize for innovators from India, Prof Thalappil<br />

Pradeep has helped millions of Punjabis<br />

access clean water with his filtration system,<br />

and implemented plans to set up water sensor<br />

networks across India as part of government<br />

programmes (p. 13).<br />

chosen an eco-friendly way of transport,<br />

setting sail to secure drinking water with<br />

solar energy as a desalination solution.<br />

In a collaborative effort, the Kori Odyssey<br />

initiative has ambitious long-term and<br />

tailor-made programmes for these rural<br />

communities. Read about its challenges<br />

the team has to overcome to best address<br />

these water stakeholders’ needs on<br />

page 16.<br />

As these communities find better ways<br />

to approach this interconnected nexus,<br />

Singapore too is tightening its water<br />

security with innovation. For instance, two<br />

Singaporean companies, NM3 Tech, a<br />

water sampling and biomonitoring startup<br />

(p. 46), and Aquarden, a specialist in<br />

destroying toxins in wastewater containing<br />

hardly degradable pollutants (p. 10), are<br />

featured for their breakthroughs in the<br />

industry.<br />

Following the outcome of 2022 UN Climate<br />

Change Conference, the adoption of the<br />

circular economy model is necessary,<br />

according to Agilent Technologies (p.32).<br />

These three domains, water, energy and<br />

food need to be managed by governments<br />

and corporations all around the world to<br />

balance the needs of communities, the<br />

economy, and the planet.<br />

GRUNDFOS COMMERCIAL BUILDING SERVICES<br />

UNVEILS NEW GLOBAL HQ IN SINGAPORE<br />

1 2<br />

Grundfos, a global manufacturer in advanced<br />

pump solutions and water technologies,<br />

inaugurated the global headquarters (HQ)<br />

of its commercial building services (CBS)<br />

division in Singapore. The move followed<br />

the demand for resource-efficient solutions<br />

to foster a sustainable built environment in<br />

Singapore and the region, where almost 56%<br />

of ASEAN’s population will be urban by 2030.<br />

Serving commercial buildings such as hotels,<br />

hospitals, office towers, airports, and data<br />

centres, Grundfos’ CBS division delivers<br />

water pump systems that serve various<br />

applications supporting the operation of these<br />

buildings, including air-conditioning, cooling,<br />

heating, fire protection, to wastewater and<br />

water disinfection.<br />

A component of Grundfos’ relocation<br />

strategy will be the Singapore Innovation<br />

Hub, which aims to leverage local knowledge<br />

to pioneer solutions for energy-efficient<br />

commercial buildings. The facility will look<br />

to bring Grundfos’ R&D capabilities closer to<br />

customers and the market, as well as provide<br />

a platform for collaboration with industry<br />

partners, customers, and researchers to<br />

co-develop energy and water-efficient smart<br />

solutions.<br />

As part of developing the Singapore<br />

Innovation Hub, Grundfos has engaged<br />

in various feedback, steering and risk<br />

management efforts since March, following<br />

which the company will embark on<br />

developing innovation initiatives, establish<br />

governance structure, and discuss areas<br />

of collaboration with potential partners.<br />

All these will contribute towards a<br />

comprehensive working plan for the new<br />

Singapore Innovation Hub by Q3 of <strong>2023</strong>.<br />

Singapore’s location as the gateway to other<br />

ASEAN countries also allows Grundfos<br />

to work closely with customers in these<br />

markets and support their urbanisation<br />

needs.<br />

Recent reports of climate change and<br />

rapid urbanisation has called for countries<br />

to examine their buildings’ environmental<br />

impact. The region’s building sector<br />

accounts for nearly a quarter of total energy<br />

consumption and energy-related carbon<br />

emissions, and this is still projected to grow<br />

by around 60% by 2030 and 120% by 2040.<br />

Space cooling is the fastest-growing use of<br />

energy in buildings globally and in ASEAN,<br />

according to International Energy Agency<br />

reports. Being a vulnerable region to climate<br />

1 Singapore was selected for the relocation based<br />

on its nation-wide commitment to sustainability<br />

through its Singapore Green Plan 2030<br />

change, the sector’s sustainability ambitions<br />

are high on the region’s agenda.<br />

Its CEO said, “Locating our CBS HQ in the<br />

heart of <strong>Asia</strong> is part of our wider business<br />

strategy of operating as a truly global<br />

company.<br />

“At Grundfos, we are committed to delivering<br />

on our net-zero targets validated by the<br />

Science Based Targets initiative (SBTi) to<br />

ensure our growth is sustainable.”<br />

Under the new CBS HQ, Grundfos will<br />

strengthen its talent pipeline to over 200<br />

employees, by bringing in global expertise<br />

and the hiring of local talents. The company<br />

will also continue its efforts in collaborating<br />

with public and private players locally.<br />

DR ANDREA RINALDO WINS STOCKHOLM WATER PRIZE<br />

Dr Andrea Rinaldo, professor of<br />

hydrology and water resources<br />

at the École Polytechnique<br />

Fédérale de Lausanne and at the<br />

University of Padova, has been<br />

named the <strong>2023</strong> Stockholm <strong>Water</strong><br />

Prize Laureate. Since 1991, the<br />

Stockholm <strong>Water</strong> Prize laureates<br />

have represented a range of<br />

water-related activities,<br />

professions, and scientific<br />

disciplines from around the world.<br />

Originally from Venice, Italy,<br />

Dr Rinaldo was chosen for his<br />

research in hydrologic science,<br />

which showed the connections<br />

between river networks and<br />

the spread of solutes, aquatic<br />

species, and diseases, according<br />

to the award. Throughout<br />

his career, Dr Rinaldo has<br />

advanced the understanding<br />

of the complex interactions<br />

between the hydrologic cycle,<br />

ecological processes and<br />

landscape evolution. At a time<br />

when hydrology was mainly<br />

associated with fluid mechanics<br />

and hydraulic engineering,<br />

he searched for alternative<br />

approaches and developed new<br />

conceptual and quantitative<br />

models to describe how water<br />

shapes the earth surface and<br />

ecosystems.<br />

The Stockholm <strong>Water</strong> Prize, a<br />

global prestigious water award,<br />

is often described as the Nobel<br />

Prize of water. The US <strong>Water</strong><br />

Environment Federation (WEF) is<br />

THE COCA-COLA FOUNDATION AND IMAGINE H2O<br />

LAUNCH WATER INNOVATION FUND<br />

The Coca-Cola Foundation and<br />

Imagine H2O, a global non-profit that<br />

accelerates and deploys new water<br />

innovations, have partnered to scale<br />

entrepreneurial solutions for the<br />

global water crisis. The sustainable<br />

access solution fund unlocks targeted<br />

grants and technical support to<br />

help communities pilot and adopt<br />

innovation, doubling Imagine H2O’s<br />

annual pilot funding budget this year.<br />

As one-third of the world’s inhabitants<br />

still lack access to safe drinking water,<br />

technologies are emerging that can<br />

help boost water supply, mitigate<br />

pollution and strengthen climate<br />

resilience. However, widespread risk<br />

aversion and financial constraints<br />

prevent utilities, businesses and other<br />

end-users from testing and validating<br />

these solutions.<br />

The solution fund creates opportunities<br />

for innovators and their customers to<br />

overcome these barriers, building on<br />

Imagine H2O’s ongoing pilot initiatives<br />

supported by philanthropic and public<br />

sector partners including OceanKind,<br />

11th Hour Racing, Enterprise<br />

Singapore, World Bank and <strong>Asia</strong>n<br />

Development Bank.<br />

Since 2018, Imagine H2O has awarded<br />

US$1.9m for 69 pilots. This support<br />

has triggered up to seven times in<br />

matching or follow-on funding from<br />

other partners. Beyond financial<br />

support, the solution fund utilises its<br />

global startup accelerator programmes<br />

and in-country networks to mentor<br />

entrepreneurs as they design, execute,<br />

and monitor the impact of these<br />

projects. Awards will be recycled<br />

back to the solution fund when pilots<br />

succeed.<br />

“This partnership marks another<br />

milestone to accelerate progress<br />

towards the UN sustainable<br />

development goals, all 17 of which<br />

will be affected by how our water<br />

resources are used, treated and<br />

managed in the future,” said Saadia<br />

Madsbjerg, president of The Coca-<br />

Cola Foundation.<br />

The solution fund will source<br />

solutions that directly enable access<br />

to safe drinking water and help<br />

communities restore or sustain<br />

water resources threatened by<br />

climate change or environmental<br />

degradation. From biosensors<br />

for rapid contamination detection<br />

to rural water supply monitoring<br />

systems, a range of technologies will<br />

be vetted from across Imagine H2O<br />

network of 175 startups.<br />

“From Johannesburg to Jakarta, the<br />

appetite to leapfrog conventional<br />

water management approaches<br />

is growing,” said Imagine H2O<br />

president Scott Bryan, “With The<br />

Coca-Cola Foundation, we will help<br />

underserved communities embrace<br />

new technologies by providing<br />

dedicated funding and insight to<br />

MEMSIFT TO RECOVER NICKEL FROM<br />

MICROELECTRONIC INDUSTRIAL<br />

EFFLUENT IN SINGAPORE<br />

1<br />

Membrane-based solutions company Memsift<br />

Innovations received a new contract from a<br />

global microelectronics corporation to build a<br />

first nickel recovery plant in Singapore using<br />

its TS-30 improved membrane distillation<br />

technology followed by pilot trials. This<br />

project builds on Memsift’s track record in<br />

developing and implementing membrane<br />

distillation technology for the treatment of<br />

industrial effluent. The project is part of an<br />

initiative to reduce the environmental impact<br />

of the microelectronics manufacturing<br />

process.<br />

The microelectronics industry generates<br />

industrial effluent containing valuable metals<br />

such as nickel, which are typically lost<br />

during conventional wastewater treatment<br />

processes. Memsift’s improved membrane<br />

distillation system recovers more than 95%<br />

of water and up to 100% nickel from the<br />

microelectronics industrial effluents,<br />

as estimated nickel recovery is about<br />

10.2 tonnes/year.<br />

The system is designed to achieve efficiency<br />

in nickel recovery while minimising energy<br />

consumption and operating costs by up to<br />

80% compared to the current method in<br />

place. It helps to reduces emission by about<br />

211 tonnes of CO2/year compared to the<br />

business-as-usual scenario. About 43%<br />

of emission reduction is due to the direct<br />

energy savings. Typically, it requires about<br />

8,436 trees to absorb the same amount of<br />

CO2 from the atmosphere over a year.<br />

120WATER NAMED CHEROKEE NATION LCR DATABASE OF RECORD<br />

Committed to providing programme<br />

management tools to rural water systems,<br />

digital water solutions provider 120<strong>Water</strong> has<br />

been selected by sovereign tribal government<br />

Cherokee Nation as its Lead and Copper Rule<br />

(LCR) database of record. The partnership<br />

will expand on a successful pilot carried out<br />

earlier this year, assisting in the preparation<br />

of Lead Service Line Inventories (LSLI) for 25<br />

small systems across northeast Oklahoma,<br />

US. The announcement took place at the<br />

Facilities Construction Spring Meeting hosted<br />

by the Indian Health Services (IHS) office of<br />

environmental health and engineering.<br />

“Since 1839, the Cherokee Nation has<br />

dedicated itself to improving the livelihood of<br />

our tribal community,” said its senior director<br />

of environmental health and engineering Billy<br />

Hix.<br />

As the first major stipulation outlined in the<br />

LCR Revisions (LCRR), water utilities have<br />

until 16 Oct 2024 to establish a preliminary<br />

inventory of all service line materials.<br />

Information must be digital and submitted<br />

to the governing body responsible<br />

for reporting in each state, which for<br />

the Cherokee Nation is the Oklahoma<br />

Department of Environmental Quality<br />

(ODEQ). The 120<strong>Water</strong> contract includes<br />

historical records review and inventory<br />

development, with funding assistance<br />

provided by the IHS.<br />

The partnership announcement came<br />

after the release of the US Environmental<br />

Protection Agency’s seventh drinking<br />

water infrastructure needs survey and<br />

assessment, which estimated US$625bn<br />

needed over the next 20 years to modernise<br />

water infrastructure. Report findings were<br />

used to determine annual funding to states<br />

through the drinking water state revolving<br />

fund. With a prediction of more than 28,000<br />

lead service lines, Oklahoma is slated<br />

to receive $28.6m for LSL Replacement<br />

(LSLR) improvements across the state. An<br />

additional $60m has been set aside for<br />

American Indian and Alaska Native water<br />

systems nationally. The Cherokee Nation<br />

hopes its work with 120<strong>Water</strong> will assist in<br />

helping obtain funds required to continue<br />

the lead remediation process beyond<br />

inventorying.<br />

Hix added, “A total of over 130 utilities within<br />

our reservation have to comply with the<br />

many facets of LCRR.”<br />

Encompassing nearly 7,000 square miles,<br />

the Cherokee Nation is a sovereign tribal<br />

government with more than 141,000 citizens<br />

residing within its reservation boundaries.<br />

Representatives from 120<strong>Water</strong> at the<br />

event included regional sales manager Jon<br />

Dawson, director of client success Logan<br />

Turner, and vice-president of sales Matt<br />

SINGAPORE FOCUS<br />

THE DESTRUCTION OF<br />

TOXINS IN WASTEWATER<br />

containing hardly degradable<br />

pollutants with Aquarden<br />

Aquarden develops and markets solutions that provide a way of treating<br />

problematic wastewater streams that have a high chemical oxygen demand (COD).<br />

reused as process water. It all takes place in<br />

a continuous, one-step process.<br />

Cost-benefit analyses show that the SCWO<br />

treatment achieves lower operating costs<br />

per cubic metre and better COD reduction<br />

compared to other destruction methods<br />

such as incineration and other chemical<br />

oxidation techniques.<br />

Aquarden’s SuperOx SCWO system<br />

Aquarden’s systems for wastewater treatment<br />

are based on a technology called supercritical<br />

water oxidation (SCWO). Supercritical is a<br />

physical state that water reaches when it is<br />

heated above 374°C and pressurised above<br />

221bar.<br />

When wastewater turns supercritical, it<br />

becomes a great medium for oxygen and<br />

organic molecules to react with one another as<br />

the solubility of inorganic substances drops.<br />

In Aquarden’s system, all hardly-degradable<br />

organic pollutants are destroyed in the oxidation<br />

process, producing only non-toxic compounds<br />

such as water, carbon dioxide, and nitrogen.<br />

SCWO TECHNOLOGY<br />

Salts and heavy metals are concentrated and<br />

removed at a temperature of around 374°C<br />

while organics oxidise further up in the reactor<br />

at 450-550°C.<br />

The salt-free supercritical wastewater is<br />

further heated to 450-550°C, where the<br />

following occurs: All organic compounds<br />

are oxidised to benign products like carbon<br />

dioxide and water. Other nitrogen containing<br />

compounds are converted into harmless<br />

nitrogen gas. Further, no dangerous gases are<br />

produced and more than 90% of the heat is<br />

reused by a built-in heat exchanger, offering a<br />

compact and energy-friendly process.<br />

The result is water that is free of salts and<br />

organics, and which can be disposed of<br />

through the sewer system, sent to sea, or<br />

The company has refined the SCWO process<br />

over years of research and development,<br />

treating wastewater with hardly degradable<br />

organic pollutants from various industries.<br />

These include the chemical, biotech,<br />

pharmaceutical, hospital, landfill, defence,<br />

and wastewater treatment industries.<br />

R&D AND PRODUCTION<br />

The company’s interdisciplinary team<br />

of mechanical and chemical engineers<br />

develops products and systems that are fully<br />

automated and in compliance with safety<br />

and environmental standards.<br />

<strong>Wastewater</strong> varies greatly in composition.<br />

Its pollutants can be medicinal drugs,<br />

hormones, per- and polyfluoroalkyl<br />

substances (PFAS), industrial chemicals,<br />

hormone-disrupting toxins, and pesticides.<br />

Its chemical staff subjects each waste<br />

stream to examination to ensure a treatment<br />

solution that conforms to discharge<br />

requirements.<br />

IN CONVERSATION WITH<br />

“THIS FILTRATION SYSTEM<br />

does not require electricity”<br />

Prof Thalappil Pradeep — winner of 2022 VinFuture Special Prize for<br />

innovators from developing countries — has developed a low-cost filtration<br />

system to remove arsenic from groundwater, helping more than<br />

7.5 million people in India get access to clean water.<br />

By Amira Yunos<br />

India’s northern state of Punjab is<br />

known as the country’s breadbasket,<br />

due to its groundwater which flows<br />

down from the Himalayas. Much of<br />

that water, however, is contaminated<br />

with naturally occurring arsenic and<br />

iron.<br />

People who rely on well water in rural<br />

areas, especially poorer members of<br />

the local communities, are at risk of<br />

arsenic poisoning from drinking the<br />

contaminated water.<br />

“The long-term impact of drinking<br />

arsenic water can be deadly, and<br />

the problem has been a pressing<br />

concern in Punjab for many years,”<br />

Prof Pradeep said. “As we expanded<br />

the reach of our activities, we found<br />

that in several regions there are<br />

other contaminants too such as<br />

manganese, chromium and uranium.”<br />

Prof Pradeep and his team<br />

Based on his research, these metal<br />

nanoparticles could be used to<br />

disrupt bonds that bind and transport<br />

arsenic in the groundwater. This<br />

separation provided a means to purify<br />

groundwater at a low cost, reaching<br />

transforming contaminated water to<br />

clean drinking water for more than 7.5<br />

million people.<br />

The arsenic and iron removal<br />

technology is due to new materials<br />

which remove the different forms of<br />

arsenic present in groundwater at<br />

equal efficiency.<br />

“The contaminated water passes<br />

through the filter, which traps the<br />

arsenic, iron, uranium, and other<br />

contaminants. The system is low-cost<br />

because it does not use expensive<br />

materials or membranes, and it does<br />

not require electricity, which makes it<br />

ideal for use in rural areas.”<br />

The system can be operated<br />

continuously with only two 15-minute<br />

maintenance procedure, once<br />

a month, and it produces less<br />

wastewater than treatment with<br />

alternate methods such as reverse<br />

osmosis (RO), according to him.<br />

For Prof Pradeep, his work is driven<br />

by a belief in the vital importance of<br />

clean water technologies for the poor<br />

and the need for low-cost solutions<br />

that can be operated continuously with<br />

minimal maintenance.<br />

IN CONVERSATION WITH<br />

TIGHTENING<br />

CYBERSECURITY<br />

in the water industry<br />

Previously, Vijay Vaidyanathan, regional vice-president, solutions engineering,<br />

<strong>Asia</strong>-Pacific and Japan, Claroty shared about the NIST framework implementation<br />

progress in the water sector. In this issue, he tells us ways to tighten cybersecurity<br />

measures in Singapore and the <strong>Asia</strong>-Pacific region.<br />

By Amira Yunos<br />

to managing cybersecurity, helping<br />

organisations to identify and prioritise<br />

their most critical assets, assess the<br />

effectiveness of their current cybersecurity<br />

measures, and implement measures to<br />

protect against potential threats.<br />

I believe that the full implementation of the<br />

NIST framework in Singapore will further<br />

enhance the country’s efforts to protect<br />

against cyber threats and secure its critical<br />

information infrastructure. The country’s<br />

commitment to cybersecurity and its strong<br />

legal framework make it well-positioned<br />

to fully adopt and implement the NIST<br />

framework, and I look forward to seeing this<br />

progress in the near future.<br />

With the Singapore’s Cybersecurity Bill<br />

passed in 2018, when and why do you think<br />

Singapore will fully implement the NIST<br />

framework implementation progress?<br />

Vijay Vaidyanathan: The implementation<br />

of the NIST framework in Singapore is on<br />

course to be fully realised as the country<br />

continues to prioritise the protection of its<br />

critical information infrastructure and national<br />

security. The Cybersecurity Bill passed in<br />

2018 serves as a strong foundation for the<br />

implementation of cybersecurity standards<br />

and best practices, including those outlined in<br />

the NIST framework.<br />

In the current digital landscape, cyber threats<br />

are constantly evolving and becoming<br />

more sophisticated, making it increasingly<br />

important for organisations to adopt a<br />

comprehensive and proactive approach to<br />

cybersecurity. The NIST framework provides<br />

a systematic and risk-based approach<br />

Despite government facilities’<br />

willingness to adopt the framework, why<br />

are resources still lacking in the water<br />

and wastewater utilities to support a<br />

robust cybersecurity programme?<br />

Vaidyanathan: There are several reasons,<br />

including the prioritisation of operational<br />

and physical security. <strong>Water</strong> and<br />

wastewater utilities may focus on physical<br />

security and operational efficiency over<br />

cybersecurity, which can result in a lack<br />

of resources being allocated towards the<br />

development of a robust cybersecurity<br />

programme.<br />

14 WATER & WASTEWATER ASIA | MAY/JUNE <strong>2023</strong>


IN CONVERSATION WITH<br />

Another reason is ageing infrastructure. Many<br />

water and wastewater utilities have ageing<br />

infrastructure, including control systems,<br />

that may not have been designed with<br />

cybersecurity in mind. Upgrading or replacing<br />

these systems to improve cybersecurity can<br />

be an investment that may be challenging<br />

for some utilities. To rectify these resource<br />

challenges, water and wastewater utilities<br />

can take several steps, including prioritising<br />

cybersecurity. Upgrading and modernising<br />

infrastructure is a critical step as well. This<br />

may involve improving or replacing ageing<br />

infrastructure, such as control systems, to<br />

boost cybersecurity efficiency.<br />

What are the cyber-physical threats and<br />

dangers to water infrastructure in the<br />

APAC region?<br />

Vaidyanathan: In the <strong>Asia</strong>-Pacific region,<br />

there have been several high-profile<br />

examples of cyber-physical threats to water<br />

infrastructure. For example, in 2016, the<br />

Maroochy Shire Council in Australia was<br />

targeted in a cyber-attack that resulted in the<br />

release of over 1 million litres of raw sewage<br />

into local waterways. In another incident in<br />

2020, a water treatment plant in Vietnam<br />

was targeted in a ransomware attack that<br />

temporarily disrupted the plant’s operations.<br />

These incidents highlight the need for<br />

increased investment in cybersecurity for<br />

water infrastructure to ensure the protection<br />

and reliability of these critical systems in the<br />

<strong>Asia</strong>-Pacific region.<br />

insights into water usage, quality, and<br />

distribution, enabling them to make informed<br />

decisions and optimise their operations.<br />

Furthermore, XIoT can help in improving<br />

the security of water supply systems and<br />

reducing the risk of water contamination and<br />

theft, ensuring that communities have access<br />

to safe and secure water supplies.<br />

For these reasons, the water industry should<br />

gear towards securing XIoT as it offers a<br />

solution for managing and securing water<br />

resources and supplies, while also providing<br />

insights and enabling better decision-making.<br />

By incorporating XIoT into their operations,<br />

companies and organisations can improve<br />

their efficiency, sustainability, and security,<br />

and contribute to a better future for both the<br />

water industry and society as a whole.<br />

How has Claroty supported the shift<br />

towards NIST framework in the water<br />

industry?<br />

Vaidyanathan: Claroty, a partner for<br />

customers in the water and wastewater<br />

sectors, applauds the industry standards<br />

and best practices that help organisations<br />

manage cybersecurity risks.<br />

Our technology and expertise help our<br />

customers and partners in keeping disruptive<br />

attacks at bay. We also understand the<br />

government’s need for enhanced visibility<br />

into the operational technology (OT) networks<br />

at the hub of indispensable services, public<br />

safety, and national security.<br />

critical assets. At Claroty, we have focused<br />

on extending the reach of our platform to<br />

cover the XIoT. We continue to build on our<br />

capabilities, including full-spectrum visibility,<br />

risk and vulnerability management, threat<br />

detection, and secure remote access controls<br />

for industrial, healthcare, and enterprise<br />

environments. Our platform allows users to<br />

extend their governance model to include the<br />

breadth of devices and systems within and<br />

connected to their environment, and to assess<br />

and strengthen their overall security posture.<br />

Our clients, on top of their existing<br />

infrastructure, utilise the component of<br />

continuous threat detection (CTD) for<br />

full spectrum OT, IoT, and IIoT visibility,<br />

continuous security monitoring, and real-time<br />

risk insights with zero impact to operational<br />

processes and underlying devices. They<br />

also use secure remote access (SRA) to<br />

safeguard the industrial networks from threats<br />

introduced via unmanaged or unmonitored<br />

access by remote users, including third-party<br />

vendors, contractors, and technicians. Finally,<br />

enterprise management console (EMC) is<br />

utilised to simplify management at scale,<br />

consolidating data from Claroty products and<br />

provide a unified view of assets, activities,<br />

and alerts across multiple sites. The Claroty<br />

Platform also integrates via the EMC with<br />

the company’s newly deployed IT security<br />

infrastructure.<br />

What is XIoT and why should the industry<br />

gear towards securing it?<br />

Vaidyanathan: The Extended Internet of<br />

Things (XIoT) is a holistic umbrella term that<br />

encompasses all cyber-physical devices<br />

connected to the internet. An organisation’s<br />

XIoT can include cyber-physical systems.<br />

By leveraging advanced technologies such<br />

as IoT sensors, cloud computing, artificial<br />

intelligence (AI), machine learning (ML),<br />

predictive technology and advance process<br />

control, the water industry can gain real-time<br />

<strong>Water</strong> facilities and utilities cannot defend<br />

what they cannot see. Technology that<br />

identifies connected assets, vulnerabilities<br />

putting those assets at risk, and provides<br />

remediation strategies are important.<br />

Secure remote access technologies<br />

purpose-built for OT that provide user<br />

provisioning, role- and policy-based access<br />

controls, alerting, and the capability to<br />

audit, investigate, and terminate potentially<br />

malicious remote sessions must be a<br />

requisite for facilities with online connected<br />

by a team of three; sailing and utilising<br />

solar energy to secure drinking water<br />

in remote areas. The team plans to visit 22<br />

IN CONVERSATION WITH<br />

Mascara, a French company<br />

specialising in water treatment<br />

solutions using renewable energies,<br />

launched the Kori Odyssey initiative<br />

to implement tailored water access<br />

programmes using solar energy<br />

in remote areas. The company<br />

developed Osmosun, a solar<br />

desalination technology. It has<br />

already installed 60 Osmosun units in<br />

15 countries around the globe, from<br />

Africa to South East <strong>Asia</strong>, and to the<br />

Pacific.<br />

The courier departed from Papeete<br />

on 15 Feb <strong>2023</strong>, and plans to<br />

visit 22 archipelagos in the South<br />

Pacific region, meeting with water<br />

stakeholders and discussing how<br />

best to address their needs.<br />

As many Pacific islands are lacking<br />

in fresh water, this autonomous and<br />

battery-free desalination technology<br />

provides sustainable and affordable<br />

water to remote communities,<br />

according to Bourillet. Kori Odyssey’s<br />

one-year itinerary includes meeting<br />

water stakeholders in these rural<br />

communities via sailboat.<br />

The objective of the coalition is to<br />

deepen the understanding of these<br />

communities’ challenges. In the<br />

operational phase, the team will install<br />

Osmosun. After which, it involves<br />

the community in the operation and<br />

maintenance of the solar desalination,<br />

cultivating a long-term service.<br />

“Desalination is not here to<br />

replace rainwater harvesting,”<br />

Bourillet added. “I would say the<br />

right solution is really a mix of<br />

the three: brackish underground<br />

water, rainwater harvesting and<br />

desalination.”<br />

But in the archipelago of low islands<br />

with no altitude, underground<br />

water is not readily available,<br />

which means a heavy reliance on<br />

rainwater. During dry seasons,<br />

accessing water becomes difficult.<br />

Mascara’s technology thus<br />

alleviates the water problem<br />

during this time. The team also<br />

hosts workshops to educate the<br />

community about its eco-friendly<br />

approach to technology, which<br />

aligns with the Pacific culture to<br />

protect its environment.<br />

“They are interested by the<br />

technology and our approach of<br />

doing it on a sailboat to spend<br />

time understanding needs of these<br />

communities,” Bourillet said, “For<br />

instance, we have a workshop at<br />

the guest house to meet water<br />

stakeholders of the island of<br />

Rangiroa to present the technology,<br />

understand the need and discuss<br />

possibilities.”<br />

THE CHALLENGES OF THE<br />

ODYSSEY<br />

Although the team has good internet<br />

connection in the middle of the ocean,<br />

having it is not enough.<br />

“The real challenge beyond any project<br />

is to have a tailor-made programme,<br />

something that is built with the<br />

community and for the community, and<br />

not imposed by a foreign company,”<br />

he added.<br />

Bourillet said that the community<br />

needs to adapt to the technology<br />

themselves to build a long-term<br />

service. However, due to the<br />

remoteness of this endeavour,<br />

logistically, transporting energy<br />

equipment and its spare parts have<br />

proven arduous. Reverse osmosis (RO)<br />

requires mechanics and electronics<br />

skills hence the longevity of this<br />

project is dependent on the skills<br />

imparted to these communities.<br />

Kori Odyssey, in response, trains the<br />

operator with a three-level operation<br />

and maintenance scheme.<br />

“We will train the operator on-site, the<br />

technician of the community of the<br />

water committee, and the municipal<br />

council for the basic and daily<br />

operation,” Bourillet said. “We have<br />

SOLAR ENERGY AS A<br />

DESALINATION SOLUTION<br />

Many remote areas already have<br />

rainwater and brackish groundwater<br />

harvesting, which are already good<br />

solutions, according to Bourillet.<br />

As desalination is more energy<br />

consuming, a mix of different<br />

resources would be the ideal<br />

solution.<br />

The team of three<br />

anticipates the scale up<br />

of the programme<br />

plans to deploy<br />

and co-build its<br />

Osmosun solar<br />

desalination<br />

solutions to a<br />

potential target<br />

of 125 villages<br />

a technical partner in the capital city<br />

that can provide outline, spare parts<br />

and support for installation after-sales<br />

service to help the daily operator in<br />

the process, and then at a third level,<br />

Mascara, where we provide support to<br />

our partner in the capital city.”<br />

Data collection is another challenge.<br />

While Mascara wants a non-electronic<br />

system to make it easy for the<br />

communities technically and<br />

financially, bringing back quality data<br />

is essential for operational feedback.<br />

data from the operator directly. This<br />

ensured reliable data collection for<br />

long-term planning to improve Kori<br />

Odyssey’s system.<br />

Further, Kori Odyssey is also<br />

collaborating with international<br />

development agencies to help these<br />

communities connect with the support<br />

from these donors. Discussions with<br />

the World Bank, Luxembourg, German<br />

and French corporations are ongoing<br />

to garner support for the beneficiaries.<br />

For Bourillet, Kori Odyssey stemmed<br />

from the idea to build an adaptive<br />

programme catapulted by on-the-ground<br />

discussions. “To me, the Pacific way is<br />

to find solutions together and that is the<br />

direction we are willing to integrate,” he<br />

said, “Technology is one thing,<br />

but having it integrate into the<br />

ecosystem is another. We are trying<br />

to build a long-term service with the<br />

people there.”<br />

Images: Mascara<br />

To solve this, the team works in other<br />

places where it is more automated to<br />

liaise with the water committee in the<br />

capital city. For instance, at the team’s<br />

recent stopover in Port Vila, Vanuatu,<br />

they relied on a water company to<br />

support the water committee. The<br />

water company then collected the<br />

Technology is one thing, but having it<br />

integrate into the ecosystem is another.<br />

We are trying to build a long-term service<br />

with the people there.<br />

pH value and conductivity. Another<br />

16 measuring stations were added<br />

which measure the additional<br />

chemical (COD) and the biochemical<br />

oxygen demand (BOD) as<br />

parameters for the organic load, as<br />

well as nitrate by means of spectral<br />

sensors, such as NiCaVis 705 IQ.<br />

The decision to use WTW online<br />

spectral sensors in river water<br />

monitoring applications, which<br />

were originally intended for use in<br />

municipal wastewater, was preceded<br />

by testing in different Khlongs. The<br />

‘very good’ match of sensor-COD<br />

and nitrate values with laboratory<br />

reference values, which was<br />

determined in the course of COD<br />

and cuvette tests, convinced Green<br />

Banyan, PCD and BMA regarding<br />

the spectral measuring principle.<br />

The continuously operating<br />

ultrasound cleaning system<br />

which is integrated in the spectral<br />

sensors and the additional installed<br />

compressed air cleaning system<br />

allowed measured values over time<br />

frames of several weeks without<br />

frequent manual cleaning of the<br />

measuring windows. The sensors<br />

were not installed directly in the<br />

Khlongs or rivers but the water<br />

sample was pumped into the<br />

measuring station on the shore by<br />

means of submersion pumps. The<br />

measuring stations are equipped with<br />

flow-through units for the sensors,<br />

data storage and modems for remote<br />

data transmission.<br />

IN THE FIELD<br />

AN ENVIRONMENTAL<br />

AIRPORT<br />

wastewater solution<br />

When a utilities and services provider was commissioned to create an<br />

environmentally critical application for one of the world’s busy airports, they<br />

collaborated with water-treatment specialist SEKO for a fail-safe solution.<br />

SEKO customised a solution for the client<br />

This multi-terminal European airport<br />

welcomes in an excess of 80 million<br />

passengers each year, and pre-pandemic,<br />

handled as many as 1,300 flights per day.<br />

Typical of such a large-scale operation, the<br />

airport’s management faced a huge number<br />

of logistical challenges to ensure flights leave<br />

safely and on time. During winter, chief among<br />

these was overcoming the effect of severe cold<br />

weather on aircraft.<br />

INDUSTRIAL-SCALE DE-ICING TO<br />

PREVENT FLIGHT CANCELLATIONS<br />

The presence of snow and ice was a major<br />

issue in aviation as it disrupts airflow over an<br />

aircraft’s wings and tail, hindering its ability to<br />

create lift and consequently preventing pilots<br />

from taking off.<br />

The airport in question was no exception, and<br />

the management knew that if this problem was<br />

not addressed, they faced the potential delay<br />

or cancellation of hundreds of flights. The<br />

subsequent disruption would cause travellers<br />

inconvenience and damage the airport’s<br />

reputation for maximising its flight capacity.<br />

To protect itself against adverse<br />

weather conditions, the airport invested<br />

in industrial-sized de-icing cannons for<br />

spraying airliners with a heated glycol fluid<br />

which would ensure that settled snow and ice<br />

melted while preventing further build-up once<br />

planes were airborne.<br />

A COMMITMENT TO MINIMISING<br />

ENVIRONMENTAL IMPACT<br />

Despite the benefits of this approach, the<br />

operator was concerned that wastewater from<br />

the process could contaminate waterways<br />

with glycol, which would potentially have a<br />

devastating effect on surrounding waterborne<br />

wildlife. With up to 1,000l of de-icer required<br />

to clear an Airbus A380, the pollution risk was<br />

significant. Further, any contamination incident<br />

would setback years of its efforts in reducing<br />

environmental impact.<br />

Airport management thus commissioned<br />

a utilities provider to build and operate a<br />

dedicated treatment works adjacent to the<br />

site to improve the quality of wastewater<br />

discharged.<br />

When designing the plant, the utilities company<br />

decided to treat wastewater via a flocculation<br />

process, whereby contaminated particles in a<br />

liquid clump together and then sink, separating<br />

them from the clean water, which would be<br />

safely discharged.<br />

<strong>Water</strong>-treatment dosing and control specialist<br />

SEKO was approached to supply an automated<br />

polymer batching system that could separate<br />

pollutants and allow treated water to be safely<br />

discharged into a nearby watercourse.<br />

Following an assessment of the site and<br />

application, the result of this process saw<br />

THE NEXT<br />

GENERATION OF<br />

ZWEEC’s biomonitoring<br />

Singapore-based water technology company<br />

ZWEEC Analytics introduces the next generation of<br />

its smart biomonitoring technology, Aquapro. Previously<br />

named AquaTEC, it improved its application, detection<br />

sensitivity, reliability, and operability.<br />

PERFORMANCE IN HIGH<br />

TURBIDITY WATER<br />

The newly launched Aquapro is<br />

designed to perform in high turbid<br />

water condition with up to 150<br />

nephelometric turbidity unit (NTU). Its<br />

artificial intelligence (AI) algorithm and<br />

visualisation enhancement enable it<br />

to distinguish the fish, even when the<br />

human eye fails to visualise due to the<br />

cloudiness of water.<br />

Aquapro is able to monitor 20 fish in<br />

motion with accuracy. The fish is locally<br />

sourced, depending on the availability<br />

in the region. In Singapore and warmer<br />

regions, the tiger barb is a common<br />

type of fish used. In colder regions such<br />

as Taiwan, shubunkin is an alternative.<br />

INDONESIA’S<br />

DAM PROJECT<br />

supports water access<br />

in tourism destination<br />

Hutama Karya uses digital monitoring software to promote safety<br />

and sustainability in key national infrastructure project.<br />

By Aude Camus, senior product marketing manager, reality modelling at Bentley Systems<br />

Hutama Karya<br />

decided to fully<br />

digitise its surveying<br />

and data collection<br />

processes<br />

Within the archipelagic nation of<br />

Indonesia, Bali is an island with an<br />

international tourism profile. But to its<br />

east in the chain of the Lesser Sunda<br />

Islands, the island of Lombok is also<br />

growing a reputation as a tourist<br />

destination.<br />

Lombok is known for Mount Rinjani,<br />

Indonesia’s second-highest volcano.<br />

Additionally, Mandalika, a resort area<br />

on the island’s southern coast, was<br />

named in 2020 as one of Indonesia’s<br />

five ‘super-priority destinations’ —<br />

sites that the Indonesian Tourism and<br />

Creative Economy Ministry is working to<br />

promote as international tourism hubs.<br />

Recently, Mandalika has attracted the<br />

2022 Indonesian motorcycle Grand<br />

Prix, which served as the second round<br />

in the international Moto Grand Prix<br />

Championship.<br />

26 WATER & WASTEWATER ASIA | MAY/JUNE <strong>2023</strong>


IN THE FIELD<br />

However, island locals are facing a daily<br />

threat, one that is also holding back<br />

the area’s tourism potential. Lombok<br />

and the larger Indonesian province of<br />

west Nusa Tenggara have experienced<br />

growing water scarcity during dry<br />

seasons, with limited water available<br />

for drinking and sanitation. This<br />

scarcity also encroaches on Lombok’s<br />

agriculture practices; the island is one of<br />

the top rice producers in Indonesia, and<br />

farming is the most common profession<br />

among locals.<br />

To provide balance in water availability<br />

between Lombok’s rainy and dry<br />

seasons, Indonesia’s directorate of<br />

general water resources tapped on<br />

Hutama Karya, a state-owned enterprise<br />

that executes infrastructure projects,<br />

to engineer a dam in the west Lombok<br />

regency. This district stretches along<br />

most of the south-western coast of<br />

Lombok. The Indonesian government<br />

has honed in on the Meninting dam as<br />

a linchpin for the development of the<br />

country’s infrastructure and economy,<br />

officially naming it a ‘national strategic<br />

project for the acceleration of economic<br />

growth in Indonesia’.<br />

However, to achieve this vision, Hutama<br />

Karya’s engineers had to navigate tricky<br />

terrain. Parts of the site chosen for the<br />

dam were difficult to access with thick<br />

trees, shrubbery and steep conditions.<br />

The undeveloped site presented<br />

an unknown degree of hazards for<br />

surveyors and construction workers.<br />

When the team attempted to survey the<br />

property using traditional methods, the<br />

data collection process was drawn-out<br />

and dangerous.<br />

Considering these challenges, Hutama<br />

Karya decided to fully digitise its<br />

surveying and data collection processes.<br />

The team used a drone with a flying<br />

distance of 7-8km to capture images and<br />

data from the site’s hardest-to-reach<br />

areas. The drone’s findings were then<br />

processed using Bentley’s 3D reality<br />

modelling and real-time visualisation<br />

software to chart maps and monitor<br />

ongoing conditions at the site, identifying<br />

any new potential work hazards over time.<br />

This methodology cut the time required<br />

for data collection and monitoring by<br />

half. In total, project engineers saved<br />

an estimated $2.1m in fees by avoiding<br />

potential work-related accidents.<br />

future projects, and digital surveyance<br />

will become a best practice.<br />

SUSTAINABLE PRIORITIES<br />

Another one of Hutama Karya’s priorities<br />

for the Meninting dam was to keep the<br />

project’s development sustainable.<br />

For instance, during construction, the<br />

company reduced the impact of tree<br />

cutting. Where trees had to be removed<br />

in the dense forest area, steps were<br />

taken to use displaced soil in another<br />

area of the project. That soil was also<br />

used to plant new trees.<br />

It was important to ensure that<br />

construction activities did not result in<br />

further contamination of the Meninting<br />

watershed. Through digital monitoring,<br />

project managers noticed that river<br />

water around the dam’s construction<br />

was becoming dirty with excavated<br />

soil and heaps, creating a potential<br />

environmental risk for people who live<br />

within a 3km radius of the dam. Project<br />

managers were then able to reduce the<br />

pollution and avoid creating ill effects<br />

for the civilians they hoped to serve with<br />

this key infrastructure project.<br />

“It will support the agricultural sector of<br />

the locals, and also support economic<br />

growth by making a new destination for<br />

the tourism sector,” said Christy Vania, an<br />

engineer building information modelling<br />

(BIM) at Hutama Karya.<br />

SAFETY MEASURES<br />

Work on the US$95.15m Meninting<br />

dam began in 2019 and should last<br />

into <strong>2023</strong>. When completed, the dam<br />

will be 79m high with a water capacity<br />

of 12 million m 3 . It will irrigate more than<br />

1,500 hectares of agricultural property<br />

and ensure the availability of clean water<br />

to nearby Lombok residents and tourists.<br />

Additionally, the dam will provide an<br />

additional 0.8MW of hydroelectric power<br />

to the community.<br />

“Because the terrain is steep, there is a<br />

high potential for landslides. But we had<br />

around 1,200,000 safe resource hours<br />

without lost time or injury,” said Vania.<br />

For the construction phase of the project,<br />

these digital visualisation tools were<br />

folded into Hutama Karya’s geographic<br />

information system (GIS) dashboard,<br />

which also integrated BIM capabilities.<br />

Post-construction, these tools will also be<br />

useful so that Indonesia’s directorate of<br />

general water resources can monitor the<br />

dam’s performance and upkeep.<br />

Vania believes that the safety and cost<br />

benefits evident from Hutama Karya’s<br />

innovations on the Mentinting dam will<br />

be carried forward into the organisation’s<br />

PERFORMING UNDER<br />

in wastewater treatment<br />

Energy Recovery’s new Ultra PX pressure exchanger delivers cost<br />

To tackle this problem, the facility<br />

enlisted Sinochem Memtech, a<br />

subsidiary of Sinochem International<br />

membrane product solutions for<br />

the water treatment industry, to<br />

design a treatment facility using<br />

a combination of technologies<br />

employing two reverse osmosis (RO)<br />

stages and an ultra-high-pressure<br />

reverse osmosis (UHPRO) stage,<br />

Sinochem reduced the process<br />

flow rate by 90%, before using a<br />

thermal process on the remaining<br />

flow to reach zero liquid discharge<br />

(ZLD). However, these processes<br />

would normally require high energy<br />

consumption, making it harder to<br />

achieve cleaner operations without<br />

incurring high costs.<br />

The estimated cost<br />

IN THE FIELD<br />

these technologies lowered the<br />

overall energy consumption for<br />

waste treatment, allowing the site<br />

to decrease both operating and<br />

capital expenses, and to reduce the<br />

investment in the thermal system. As<br />

an added benefit, treated freshwater<br />

is also circulated back into the battery<br />

production facility, creating a closed<br />

water system that slashes water<br />

consumption and associated costs.<br />

CLEANER OPERATIONS WITHOUT<br />

HIGHER ENERGY CONSUMPTION<br />

This site was the first to commission<br />

an Ultra PX in early 2022. Site<br />

visits were conducted to confirm<br />

performance of the Ultra PX. While the<br />

facility has yet to ramp up to its full<br />

capacity, under real-world operating<br />

conditions, the PX achieved an<br />

efficiency of more than 95%, and the<br />

Ultra PX an efficiency of more than<br />

93%. With this savings, the payback<br />

for the equipment will be less than<br />

two years even at reduced feedwater<br />

levels of total dissolved solids (TDS).<br />

As the plant continues to increase<br />

TDS concentrations and system<br />

pressures, increased energy savings<br />

can be expected.<br />

The PX accommodates a wide<br />

operating range for flow and<br />

pressure. The waste stream<br />

parameters from a cathode<br />

manufacturing plant can vary<br />

in terms of flow rate, TDS, and<br />

temperature, which will lead to wide<br />

flow and pressure operating ranges<br />

for RO processes. The Ultra PX can<br />

accommodate these changes while<br />

maintaining performance.<br />

“By integrating the PX and the<br />

Ultra PX into our high-pressure and<br />

ultra-high-pressure concentration<br />

process sections, energy consumption<br />

in the concentration process is reduced<br />

by about 51% and energy consumption<br />

across the entire wastewater treatment<br />

system is reduced by 4-5%,” Liu<br />

GenTing, vice-president of technical,<br />

Sinochem Membrane Technology said.<br />

“The result is a membrane concentration<br />

system that is more affordable and more<br />

energy efficient, thereby reducing the<br />

investment and operation expenses<br />

of the downstream evaporation<br />

crystallisation system.”<br />

The Bailonggang wastewater<br />

treatment plant in Shanghai, China<br />

is said to be one of the largest in<br />

<strong>Asia</strong> and has been in operation<br />

since 1999. In 2010, ANDRITZ built<br />

an adjacent sludge drying plant<br />

to process part of the sludge in<br />

phase one. The remainder was<br />

transported to landfill, which<br />

proved problematic given the vast<br />

quantities requiring disposal and<br />

increasing distance to transport<br />

the sludge to available sites.<br />

Thus, the Shanghai government<br />

looked for an environmentally<br />

friendly solution involving<br />

sludge incineration. “ANDRITZ<br />

had worked closely with the<br />

Bailonggang operators when we<br />

installed phase one. Previously,<br />

we also had delivered China’s<br />

first municipal sludge drying plant<br />

plant to generate power from<br />

sludge. Hence, we decided to<br />

propose a complete ANDRITZ<br />

project manager.<br />

The company proposed a<br />

package that included sludge<br />

handling and drying systems,<br />

incineration systems, flue<br />

time,” said Christian Lackinger,<br />

ANDRITZ project director. The<br />

Bailonggang plant has been<br />

running since early 2021.<br />

LARGE AND ECO-FRIENDLY<br />

The ANDRITZ plant at Bailonggang<br />

is a sludge drying and incineration<br />

plant that handles 3,000 tonnes<br />

of wet sludge per day, according<br />

to the group. This is equivalent to<br />

about 130 40-ft containers full of<br />

sludge every day.<br />

Combustion takes place in six<br />

‘EcoFluid’ bubbling fluidised bed<br />

boilers, each with a firing capacity of<br />

100 tonnes of dry substance a day.<br />

The boilers are fed with a mixture<br />

of fully dried and wet sludge. The<br />

organic components of the sludge<br />

produce energy in the boiler, and<br />

the remainder is collected as ash in<br />

silos as part of the flue gas treatment<br />

system. The incineration plant is<br />

equipped with a multi-stage flue gas<br />

treatment system, the operational<br />

emission values of which are below<br />

THE WATER-ENERGY-FOOD<br />

nexus<br />

Of all the natural resources, water, energy and food<br />

are most needed to sustain life on earth. The<br />

interconnected water-energy-food nexus forms the<br />

core of the 17 sustainable development goals (SDGs)<br />

that make up the UN 2030 Agenda.<br />

By Chow Woai Sheng, Singapore general manager and vice-president of<br />

global instrument manufacturing, Agilent Technologies<br />

of all water withdrawals are used by<br />

agriculture and 90% of global power<br />

generation is water-intensive, while it<br />

typically takes between 3,000-5,000l<br />

of water to produce 1kg of rice.<br />

Despite the close relationship of<br />

water, energy, and food, different<br />

people in separate agencies perform<br />

the policymaking and funding of these<br />

resources, creating a silo that may<br />

lead to negative trade-offs impacting<br />

policy and technological choices.<br />

Urgent scale-up and coordinated<br />

actions by all countries are needed<br />

to accelerate SDG implementation to<br />

get back on track and chart a course<br />

for better recovery. Policy makers<br />

today shape their opinions based on<br />

science to make sound decisions.<br />

With increasing investments from<br />

governments in disruptive research<br />

projects to unlock technological<br />

bottlenecks, the emphasis is on<br />

resource recovery as the key to<br />

climate solutions.<br />

<strong>Water</strong> quality testing<br />

Science is responsible for<br />

humankind’s achievements, from<br />

small incremental improvements that<br />

scientists make daily to life-changing<br />

discoveries that ensure the safety and<br />

quality of our water, food, and energy.<br />

In South East <strong>Asia</strong>, the crises of<br />

the pandemic, climate change,<br />

and economy have magnified the<br />

challenges of achieving the SDGs. As<br />

the region continues looking for better<br />

policy options and initiatives in resource<br />

Globally, governments and companies<br />

have the ability to replace fossil fuel<br />

HOW OPERATORS<br />

REHABILITATE<br />

FIRE WATER MAINS<br />

with trenchless<br />

technology<br />

A functional fire-extinguishing system is<br />

the prerequisite for an operating permit<br />

in the industrial sector. Chemical plants,<br />

refineries or airports all need it. For its<br />

permanent maintenance, operators<br />

must test their fire water mains<br />

regularly. Any weak points or damages<br />

discovered in the process must be<br />

remedied to ensure the lines function<br />

properly in the event of a fire.<br />

TECHNICAL CHALLENGES FOR<br />

OPERATORS<br />

Operators carry out flow rate<br />

measurements periodically for<br />

above-ground pipelines. In the case of<br />

underground fire water mains, however,<br />

tests may lead to pipeline breaks. In a<br />

deployment simulation or a hazardous<br />

situation, fire water is forced through<br />

pipelines at increased pressure.<br />

Damaged, ageing or even corroded<br />

pipelines cannot withstand this<br />

pressure. Repairs to these damages are<br />

usually only a short-term remedy, since<br />

the pressure in the pipe seeks the next<br />

weak point, causing further damages.<br />

A multitude of other<br />

transport and supply<br />

lines in the facility often<br />

hinders accessibility of<br />

fire water mains to be<br />

rehabilitated<br />

Refurbishing existing fire-extinguishing<br />

systems in buildings is gruelling,<br />

but indispensable. How does Primus<br />

Line, the trenchless technology for<br />

pressure pipe rehabilitation, serve as<br />

the cost- and time-saving alternative?<br />

If operators in the industrial sector use<br />

seawater or salt water for firefighting,<br />

the transportation can affect the<br />

pipeline and make it corrode — steel<br />

pipes or cast-iron pipes without a<br />

cement lining are examples. These can<br />

then no longer absorb the operating<br />

pressure.<br />

“Accessibility for the rehabilitation of<br />

fire water mains also plays a role in<br />

industrial plants,” said Andreas Gross,<br />

head of the water international business<br />

unit with Rädlinger Primus Line.<br />

“The pipelines are frequently laid under<br />

access roads, larger asphalt surfaces<br />

or embedded in concrete. Or there is a<br />

multitude of other transport and supply<br />

lines in the facility. The fire water mains<br />

branch out to hydrants, for example. In<br />

these cases, an open-trench method<br />

FOCUS<br />

with heavy equipment such as excavators<br />

would involve high costs and possibly<br />

restricted operation, due to strict safety<br />

regulations and protocols.”<br />

ECONOMIC CHALLENGES FOR<br />

OPERATORS<br />

The economic challenges include, above<br />

all, repairs of suddenly occurring damages.<br />

These are cost-intensive and as mentioned,<br />

usually only successful for a short time.<br />

Operators need to consider permits to enter<br />

the site, scheduling of repair activities, and<br />

impact on productive operation.<br />

In a study, a refinery operator compared the<br />

repair work expenses using conventional<br />

construction methods and Primus Line at<br />

one of his sites. In their case, trenchless<br />

rehabilitation reduces the costs per metre<br />

to around half, whereas the metres of pipe<br />

rehabilitated per month increase by a factor<br />

of 10-15.<br />

Existing shafts can also be used as access points for trenchless rehabilitation<br />

The same operator also accumulated the<br />

repair costs, including follow-up costs, for a<br />

three-digit number of leaks at one location<br />

over a period of 13 years. The result was<br />

an amount in the low double-digit millions.<br />

Rehabilitation of these leaks with Primus Line<br />

would limit the renovation work to five years,<br />

reducing the investment sum for the execution<br />

period by a third without any follow-up costs.<br />

TRENCHLESS SYSTEMS PREFERRED<br />

Seamlessly manufactured hose liners such as<br />

Primus Line only require small construction<br />

pits at the beginning and end of the<br />

rehabilitation section to pull it into the pipe<br />

to be renovated. These pits can be dug out<br />

with a suction excavator or even by hand in<br />

extreme cases. Likewise, existing shafts can<br />

serve as access points.<br />

Furthermore, insertion only needs few<br />

equipment; one pulling winch is sufficient.<br />

Fewer equipment can free up more staff for<br />

other purposes. The insertion speed of up<br />

to 10m/min reduces installation time to a<br />

minimum.<br />

If damage occurs suddenly, refurbishment<br />

can be quickly carried out when hose liners<br />

are stored on site, while regularly maintaining<br />

maintenance windows that are available at<br />

short notice. Not even requiring external<br />

installation personnel, Rädlinger Primus<br />

Line trains the operators accordingly so that<br />

they can carry out the renovation activities<br />

themselves.<br />

There are no follow-up costs after a<br />

rehabilitation with Primus Line since the<br />

manufacturer has designed for a service life<br />

of 50 years. In a refinery at an Austrian airport,<br />

1,300m of fire water mains were rehabilitated<br />

with the inliner 15 years ago. The Primus<br />

Line is still functioning today, proving its<br />

durability. It is common for fire water mains to<br />

run in horizontal or vertical 90° bends. Under<br />

appropriate conditions, the flexible Primus<br />

Line goes up to four 90° bends. Bends up to<br />

45° are standard.<br />

As-built plans in industrial facilities are<br />

frequently not up to date so the on-site<br />

installation team must react flexibly. Due to<br />

the structural conditions or the assignment<br />

to danger zones, it is often not permitted<br />

to inspect pipes for rehabilitation with a<br />

camera initially. Obstacles or discrepancies<br />

are thus only detected during liner insertion<br />

on site.<br />

“Safety is the top priority for operators of<br />

industrial plants so [we tested] our hose<br />

liner several times for fire resistance in the<br />

presence of independent testing companies,”<br />

Gross said. “The result is reassuring. If the<br />

pipe is filled with fire water, it has a cooling<br />

effect, and the liner shows scorch marks at<br />

the outer of its three layers. The inner layer<br />

and the reinforcing aramid fabric, however,<br />

are not damaged by either selective or<br />

extensive heat input. Functionality is ensured<br />

even if the fire water main itself [is] affected by<br />

the fire.”<br />

“Pipe rehabilitation with Primus Line increases<br />

efficiency, reduces investment and operating<br />

costs and extends the service life of the<br />

fire water mains, convincing arguments for<br />

trenchless methods,” added Gross.<br />

THE ‘FIDO WAY’<br />

to find and fix water leaks<br />

FIDO Tech was founded in October 2019 as a direct response<br />

to the global issue of leakage and non-revenue water.<br />

Today, FIDO works across the globe with water utilities,<br />

aiming to end water scarcity for all.<br />

to prioritise the largest leaks. With<br />

reliable data, utilities can fix their leaks<br />

at pace and dig more accurately.<br />

In January <strong>2023</strong>, the FIDO direct<br />

service (FIDO Direct) was launched. An<br />

AI-led service, FIDO Direct harnesses<br />

FIDO AI to offer a leakage reduction<br />

on any pipe material, including plastic.<br />

Engineers follow the AI to mark up<br />

the leak for the utility to dig and<br />

repair, leaving the simple sensors —<br />

‘FIDO bugs’ — to validate the repair.<br />

Post-repair, FIDO AI calculates the<br />

success of the repair, checking that<br />

no further leaks have been caused as<br />

a result of that repair and then reports<br />

on the volumetric of water which has<br />

WATER ISSUES IN INDONESIA<br />

Indonesia’s local water companies,<br />

known as PDAMs, face challenges in<br />

providing affordable and accessible<br />

drinking water that meets standards in<br />

both quantity and quality for citizens.<br />

Further, insufficient investment in the<br />

water sector has resulted in a shortage<br />

of proper water treatment plants,<br />

storage facilities, and distribution<br />

networks. Many of PDAMs’ distribution<br />

networks were built decades ago<br />

without good record-keeping, resulting<br />

in less precise pipeline mapping.<br />

• Flow management<br />

• IoT based multisensor<br />

• Smart electricity panel<br />

• <strong>Water</strong> quality<br />

monitoring<br />

Combined with a lack of a real-time<br />

monitoring system, no early warning<br />

system is available to inform the water<br />

company beforehand when there is<br />

potential leakage. All these prolong<br />

maintenance, leading to higher<br />

non-revenue water (NRW) rates.<br />

The average national NRW in 2021<br />

is 33.24%; but this may be higher as<br />

many PDAMs are still facing unreliable<br />

automatic and real-time water loss<br />

detection and measurement systems.<br />

performance in Indonesia. In the<br />

absence of proper water production<br />

and distribution management, we risk<br />

losing the chance to preserve water<br />

resources and meet future water<br />

demands.<br />

BSA believes that integrating water<br />

management infrastructure, risk<br />

management and data analysis will<br />

give feasibility on water management<br />

to support faster decision-making<br />

and smoother operations through<br />

a multi-dimensional ICT-based<br />

approach.<br />

SWGM AS SOLUTION FOR<br />

WATER MANAGEMENT<br />

BSA has developed a smart water<br />

grid management (SWGM) solution<br />

that comprises various dimensions in<br />

its implementation. This is a step-up<br />

from the enterprise resource planning<br />

(ERP) administration system, which<br />

is used by more than 100 Indonesian<br />

water companies, launched 14 years<br />

ago. This is part of BSA’s commitment<br />

to improve water management<br />

technology.<br />

The risk analysis on water resources<br />

section analyses water resources<br />

and its usage by mapping water<br />

demand in the area and the potential<br />

availability of influent water (Fig. 1).<br />

This enables water companies to<br />

manage their water resources so<br />

that they meet the standard quantity<br />

and quality for customers and the<br />

community. The data is collected<br />

and analysed real-time as well as<br />

periodically, which will help PDAMs<br />

to quickly obtain information related<br />

to water production and distribution<br />

conditions. Various sensors are<br />

installed, such as pressure sensors,<br />

flow sensors, electricity sensors,<br />

water level and quality sensors to<br />

capture real-time data in the field.<br />

FOCUS<br />

INTEGRATED SYSTEM<br />

SWGM is an ecosystem that gives<br />

the ability for PDAMs to monitor the<br />

flow of the water, from production,<br />

transmission, distribution to<br />

consumption at customer level (Fig. 2).<br />

It shows water usage, water balance<br />

and the leakage pre-detection along<br />

the piping system through a single<br />

integrated dashboard. This is the<br />

multi-dimensional concept promoted<br />

by SWGM.<br />

Multiple IoT-based sensors are<br />

installed at pre-determined points<br />

from production to distribution to<br />

provide real-time reports on the<br />

conditions of water flows, water usage<br />

and asset’s performance in the field.<br />

Any anomaly data can be obtained in<br />

real time, hence the alert, root cause<br />

and corrective suggestion can be<br />

sent directly to the field operator’s<br />

device instantly. This integration will<br />

allow PDAMs to identify, analyse and<br />

formulate solutions. Furthermore, with<br />

the application of machine learning<br />

(ML), this system will be more precise<br />

in giving solutions through bigger<br />

data and cases that have been solved<br />

before.<br />

logger built by<br />

BSA to log and<br />

send data from<br />

multiple sensors<br />

Integrated with Web geographic<br />

information systems (GIS), this<br />

data will display what is happening<br />

according to the location point.<br />

The system can also easily isolate<br />

data, narrowing down the source<br />

of the problem. Moreover, its<br />

cross-platform integration will make<br />

it easier for related departments to<br />

receive alerts via the mobile app<br />

and cloud-based messaging app<br />

Telegram. Officers-in-charge can then<br />

carry out maintenance and repair<br />

work. They can also input survey<br />

results and maintenance activities<br />

through the same application,<br />

documenting all administrative and<br />

technical processes.<br />

The flow of the water supply chain<br />

system can be visualised from<br />

production to consumption, complete<br />

with data from the various sensors.<br />

The water supply chain system is<br />

able to provide both technical data<br />

and financial insight. Soon, it will also<br />

be able to simulate the expansion of<br />

PDAMs’ pipeline networks.<br />

DECISION SUPPORT<br />

The data presented will provide<br />

information for fast decision-making in<br />

PDAMs’ operations. Stakeholders such<br />

as field officers and directors<br />

will be able to access real-time and<br />

historical data for policymaking.<br />

The data is visualised in a mobile<br />

dashboard with a command<br />

centre display for coordination<br />

between departments. In the next<br />

phase of development, whenever a<br />

solution, asset or action is needed,<br />

it will be done through the smart<br />

remote control system, which<br />

is integrated with the SWGM to<br />

execute more automatic action or<br />

decision.<br />

TIRTA SANJIWANI’S<br />

IMPLEMENTATION IN BALI<br />

Tirta Sanjiwani is a PDAM that<br />

serves 61,000 households in Gianyar<br />

regency, Bali and supplies water for<br />

about 469,000 lives. As BSA’s client<br />

that has committed to implement<br />

SWGM in the early stages, it had<br />

installed several IoT-based sensors<br />

at several determined points from<br />

a district meter area (DMA) since<br />

2021 (Fig. 3). Adopting WebGIS,<br />

Tirta Sanjiwani was able to identify a<br />

drop in water pressure which causes<br />

service disruption.<br />

3<br />

In <strong>2023</strong>, Tirta Sanjiwani and BSA<br />

had agreed to implement a more<br />

comprehensive SWGM solution,<br />

which piloted in the Blahbatuh<br />

technical zone. The pilot project<br />

isolated water flow from production<br />

to consumption of 70 households.<br />

A water level sensor was installed<br />

in the reservoir to provide real-time<br />

information to prevent under- and<br />

over-capacity. The minimum<br />

level of water was adjusted to the<br />

customer’s water demand level so<br />

that water continuity is maintained.<br />

4<br />

Pressure and flow sensors were<br />

also installed in critical distribution<br />

networks to help the water company<br />

identify a drop in water pressure<br />

early. On the end-user side, smart<br />

water meters were installed, which<br />

made NRW rate more accurate since<br />

the water usage data is measured in<br />

real-time (Fig. 4).<br />

After all the sensors were installed,<br />

the system was able to provide a<br />

comprehensive picture of the water<br />

distribution process. This data<br />

was displayed on the supply chain<br />

system portal and the integrated<br />

command centre (ICC) (Fig. 5).<br />

Anomaly alerts were flashed on<br />

the officer’s mobile phone, making<br />

it easier to check. The progress of<br />

repairs was monitored through the<br />

ICC.<br />

The SWGM solution helps PDAMs<br />

manage water distribution, detect<br />

water leaks, identify a decrease in<br />

water quality, and control the supply<br />

of clean water to consumers. It runs<br />

on a subscription business model for<br />

those companies that face investment<br />

issues. By minimising water losses and<br />

ensuring water continuity, this solution<br />

unlocks these Indonesian companies’<br />

capacity development and expansion<br />

to provide drinking water.<br />

leaders supported by Enterprise<br />

Singapore and PUB, Singapore’s<br />

National <strong>Water</strong> Agency. NM3 leverages<br />

its expertise in IoT and big data<br />

analytics to deliver advanced systems<br />

that monitor the quality of water,<br />

air, and soil. These systems enable<br />

stakeholders to take action towards<br />

environmental sustainability and<br />

responsible resource management.<br />

AUTOSAMPLER<br />

NM3’s autosampler boasts a<br />

range of applications in municipal,<br />

industrial, and agricultural wastewater<br />

management; environmental monitoring<br />

and pandemic surveillance. It comes<br />

equipped with accurate sampling with<br />

sampling needs of a range of<br />

industrial processes.<br />

Agricultural wastewater from farming<br />

activities, such as irrigation, animal<br />

husbandry, and crop cultivation, can<br />

contain harmful contaminants such<br />

as pesticides, fertilisers, and heavy<br />

metals that pose environmental and<br />

health risks. NM3’s autosampler<br />

operates in all weather conditions<br />

to sample various soil conditions.<br />

Its rugged design enables efficient<br />

sampling to improve the quality and<br />

safety of agricultural wastewater<br />

management.<br />

Groundwater is a resource that<br />

supplies drinking water to millions of<br />

people worldwide. However, it can<br />

be susceptible to contamination.<br />

Proper monitoring and sampling<br />

of groundwater are crucial to<br />

identify negative impacts, such as<br />

over-abstraction, reduced recharge<br />

and pollution. With the autosampler,<br />

collecting samples at depths of up<br />

to 30m below ground is possible.<br />

It allows data capture and sharing<br />

for download, covering a large<br />

catchment area to improve the safety<br />

and quality of groundwater.<br />

Environmental monitoring is critical<br />

for identifying and managing pollution<br />

risks to air, water, and soil. Again,<br />

the autosampler detects and<br />

mitigates contaminants to ensure<br />

the well-being of both public health<br />

and the environment.<br />

Pandemic monitoring helps identify<br />

and prevent the outbreak and spread<br />

of infectious diseases, such as<br />

COVID-19. <strong>Wastewater</strong> samples is<br />

collected by NM3’s autosampler to<br />

identify the presence of biological<br />

contaminants from household<br />

wastewater, hospitals, sewer<br />

network and wastewater treatment<br />

plants. Regular wastewater-based<br />

epidemiology on health markers can<br />

generate insights into pharmaceutical<br />

consumption, disease prevalence,<br />

antimicrobial resistance and chemical<br />

exposure within communities in<br />

order to take preventive actions to<br />

safeguard public health.<br />

MICSENSE<br />

<strong>Water</strong> treatment plants play a<br />

role in ensuring clean water for<br />

consumption. However, these plants<br />

are vulnerable to infestations of<br />

chironomid larvae, commonly known<br />

as midges. Regular monitoring helps<br />

detect early signs of infestation, but<br />

the current monitoring method is<br />

laborious and time-consuming. It<br />

relies on plant operators to manually<br />

collect water samples and trained<br />

analysts to identify and count live<br />

and dead chironomid larvae under a<br />

microscope.<br />

The process of manually collecting<br />

and analysing samples can take<br />

up to several hours, leaving water<br />

treatment plants at risk of missing<br />

critical warning signs. Additionally,<br />

this method is prone to errors due<br />

to the subjective nature of manual<br />

analysis.<br />

To streamline the detection of<br />

chironomid larvae in water treatment<br />

plants, PUB and NM3 proposed a<br />

system that automates the sampling<br />

and analysis process. With the new<br />

system, chironomid larvae in 1,000l<br />

The multifilter concentrator subsystem,<br />

featuring a stainless-steel filter<br />

with a pore size of 40μm, is used to<br />

concentrate the larvae in the water<br />

sample. The trapped larvae are then<br />

flushed down into a small volume of<br />

concentrated sample and transferred<br />

to the optical detector for image<br />

capturing using a scanning imaging<br />

system. The computing processor<br />

analyses the morphology and<br />

movement of the trapped particles and<br />

compares the results with the derived<br />

image database.<br />

The working prototype was installed<br />

at a PUB installation for a three-month<br />

site trial, during which the system<br />

continuously operated under a<br />

24/7 mode. The system’s stability<br />

was validated with 1,744 samples<br />

analysed on-site, and the detection<br />

accuracy was verified with 151 blind<br />

test samples spiked with varying<br />

numbers of chironomid larvae. The<br />

system achieved an accuracy of over<br />

80% in detecting chironomid larvae.<br />

An upgraded version of the system,<br />

called MicSense, with better stability,<br />

has been developed and adopted<br />

by PUB for official deployment in its<br />

waterworks.<br />

BACSENSE<br />

To ensure the safety of drinking water,<br />

the bacteria Escherichia coli (E. coli)<br />

is monitored by PUB’s water quality<br />

monitoring programme in Singapore.<br />

Traditionally, water samples are<br />

collected and tested using plating<br />

or enzyme assay methods in a lab,<br />

which can take up to 24hrs. NM3 has<br />

developed a new portable system for<br />

rapid bacteria detection that utilises<br />

an enzyme assay-based detector with<br />

a microfluidic chip cartridge design.<br />

The new system has been optimised<br />

to increase sensitivity, miniaturise size,<br />

and reduce testing time to 6hr.<br />

The microfluidic chip works by<br />

concentrating bacteria from a water<br />

sample onto a 0.22µm filter in a 200µl<br />

volume reaction chamber. Selective<br />

culture media is then introduced to<br />

activate the target bacteria, such as<br />

E. coli or total coliform. A mixture<br />

reagent is used for enzyme extraction,<br />

activation, and hydrolysis reaction<br />

in sequence. The final solution is<br />

transferred from the filtration part of<br />

the chip to the detection part, where<br />

a specific fluorescent substance is<br />

tested using a sensitive confocal<br />

optical detector with suitable light<br />

source and optical filter set. The entire<br />

process is automatic and programmable,<br />

and includes temperature control to<br />

ensure repeatability of testing results for<br />

different bacteria species.<br />

The system has achieved a two-fold<br />

increase in sensitivity due to the<br />

recipe optimisation of the enzyme<br />

assay test reagent, micro-litre level<br />

reaction chamber, intracellular enzyme<br />

extraction, and confocal optical detector<br />

compatibility with the microfluidic<br />

chip. The detection results include the<br />

existence and concentration of the<br />

target bacteria, and testing accuracy of<br />

higher than 90% can be achieved. The<br />

current signal database includes E. coli<br />

and total coliform, with work in progress<br />

to develop the library for other bacteria<br />

species.<br />

This new system improved in the<br />

monitoring and management of water<br />

microbiological safety, allowing for<br />

rapid on-site testing and prompt alerts if<br />

necessary. The system has been tested<br />

on samples collected from different<br />

locations in Singapore, including<br />

non-spiked tap water samples and<br />

spiked water samples that showed higher<br />

intensity increase over time.<br />

SABO AUTOMATED<br />

INDUSTRIAL WASTEWATER<br />

TREATMENT SYSTEMS<br />

for environmental compliance<br />

For industrial facilities,<br />

complying with the US Environmental<br />

Protection Agency (EPA) and local wastewater<br />

regulation have become easier with more<br />

fully automated, wastewater treatment<br />

systems from Sabo Industrial Corporation,<br />

a New York-based manufacturer, distributor<br />

and integrator of industrial waste treatment<br />

equipment and solutions, including<br />

batch and fully automated systems,<br />

Cleartreat separating agents, bag filters,<br />

and accessories. These meet regulatory<br />

wastewater requirements, and reduce the<br />

cost of treatment, labour, and disposal when<br />

Cleartreat separating agents are also used.<br />

In contrast to labour-intensive multiple-step<br />

processes, automated wastewater treatment<br />

can help to streamline production, usually<br />

with a one-step process, while lowering costs<br />

at industrial facilities.<br />

An automated wastewater treatment<br />

system can eliminate the need to<br />

In contrast<br />

to labour-intensive<br />

multiple-step processes,<br />

automated wastewater<br />

treatment can help to<br />

streamline production,<br />

usually with a one-step<br />

process<br />

monitor equipment in person while<br />

complying with EPA and locally mandated<br />

requirements. Such automated systems<br />

separate suspended solids, emulsified<br />

oil and heavy metals, and encapsulate<br />

the contaminants, producing an easily<br />

de-waterable sludge in minutes. The<br />

water is typically then separated using a<br />

de-watering table or bag filters before it is<br />

discharged into sewer systems or further<br />

filtered for reuse as process water. Other<br />

options for de-watering include using a<br />

filter press or rotary drum vacuum. The<br />

resulting solids are non-leachable and are<br />

considered non-hazardous, so they will<br />

pass all required testing.<br />

These systems are available as manual<br />

batch processors, semi-automatic, or<br />

automatic, and can be designed as a<br />

closed loop system for water reuse or<br />

provide a legally dischargeable effluent<br />

suitable for the sewer system. A new,<br />

fully customised system is not always<br />

required. In many cases, it can be faster<br />

and more cost-effective to add to or<br />

modify an industrial facility’s current<br />

wastewater treatment system when this<br />

is feasible.<br />

Because of the importance of separating<br />

agents for wastewater treatment, Sabo<br />

uses a type of bentonite clay in a line of<br />

wastewater treatment chemicals called<br />

Cleartreat. This line of wastewater<br />

treatment chemicals is formulated to<br />

break oil and water emulsion, provide<br />

heavy metals removal, and promote<br />

flocculation, agglomeration and<br />

suspended solids removal.<br />

Today’s automated systems along with<br />

Cleartreat separating agents can provide<br />

manufacturers an easy, cost-effective<br />

alternative so they remain compliant with<br />

local ordinances and the EPA. These<br />

systems do not require much attention<br />

and can be more economical than paying<br />

fines or hauling.<br />

NEW VERDERFLEX<br />

DURA 80<br />

peristaltic pump<br />

Netherlands pump manufacturer<br />

Verder Liquids has introduced the new<br />

Verderflex Dura 80 peristaltic pump, an<br />

industrial peristaltic pump designed for<br />

applications in the process industry.<br />

The Dura 80 has a flow rate of 42m³/h<br />

and a maximum differential pressure<br />

of 16bar, making it ideal for high-flow<br />

applications. The key features are the<br />

lifting point for supporting the front<br />

cover if it needs removal; the lubricant<br />

filling point that allows easy access<br />

without requiring the removal of other<br />

bolting; and the access cover at the<br />

bottom of the front panel to allow<br />

cleaning of any debris during hose<br />

change. These new features are based<br />

on user feedback and are designed<br />

to provide easier operation and<br />

maintenance.<br />

“The Verderflex Dura 80 is the latest<br />

addition to our Dura range,” said<br />

Michael Homer, managing director at<br />

Verder UK. “This pump sets standards<br />

in performance and ease of use,<br />

providing a solution for applications<br />

where high flow and discharge<br />

pressure are required.”<br />

The VerderFlex<br />

Dura 80<br />

Verder presents a range of pumps for<br />

the pumping industry. The portfolio<br />

includes in-house produced robust<br />

peristaltic pumps, air-operated<br />

diaphragm pumps, electric double<br />

diaphragm pumps, and high-efficiency<br />

stainless steel centrifugal pumps<br />

and mixer solutions. This range of<br />

solutions ensures adaptability to<br />

the individual requirements of its<br />

customers.<br />

SURFCLEANER<br />

completes pine oil<br />

clean-up for an<br />

European port<br />

SurfCleaner deployed<br />

SCO 1000 skimmer/<br />

separator device,<br />

within 90mins of<br />

the alarm<br />

Swedish water treatment specialist<br />

SurfCleaner has completed its first<br />

pine oil clean-up project for a major<br />

European port.<br />

The work was delivered within the<br />

inner harbour of an international<br />

logistics and cargo handling hub,<br />

following a pine oil leak during the<br />

ship-to-shore transfer process. The<br />

incident happened after an operator<br />

within the port experienced a<br />

leak causing pine oil to enter the<br />

stormwater system.<br />

Its engineer Ricardo Cambra said<br />

that there was a vacuum truck<br />

attempting to siphon the surface water.<br />

Its SCO 1000 device performed an<br />

operation separating and collecting<br />

the pine oil from within the harbour’s<br />

water treatment plant basin. “Within<br />

24hrs of this first call-out, further pine<br />

oil residue was found within a well<br />

connected to the sewerage system<br />

where we again installed a SCO 1000<br />

device to tackle the issue,” he added.<br />

“Pine oil is a popular solvent, used in<br />

industrial applications for gums, resins,<br />

and other substances. However, it<br />

presents an issue when it comes to<br />

spills. In this instance, it reacted with<br />

other petroleum-based products and<br />

emulsified creating a tough sludge,<br />

which is difficult to collect. If it enters<br />

the sewerage network, it travels to<br />

the water treatment system where it<br />

can damage equipment such as sand<br />

filters, which are costly to replace.”<br />

SurfCleaner is said to be the world’s<br />

first hybrid skimmer separator that<br />

treats a variety of water surface<br />

contaminants — including oil, diesel,<br />

petrol, plastics, sludge and other<br />

pollutants. The technology has<br />

potential across the maritime industry<br />

including harbours, coastlines and<br />

nearshore markets, with the group<br />

partnering with UK operation Briggs<br />

Marine to extend its market reach.<br />

According to statistics from the<br />

International Tanker Owners Pollution<br />

Federation (ITOPF), most oil spills<br />

originate near port. The non-profit<br />

organisation — which provides<br />

technical advice for ship-sourced spills<br />

— calculates that circa 80pc of tanker<br />

spills arise from operational incidents<br />

including loading, discharging and<br />

bunkering.<br />

Ricardo said, “Our lightweight machines<br />

were easy to transport and deploy in<br />

restricted locations. They can be moved<br />

by one person and run autonomously<br />

if necessary, managing oil spills across<br />

different areas, from wells, basins, plant<br />

operations to the harbours.<br />

“SurfCleaner’s machines are also<br />

capable of removing and separating<br />

water sheen, which is relevant in<br />

oil-spill clean ups, removing the need<br />

for costly absorbents. Due to the level<br />

of performance, the client has kept<br />

the machines on site through a rental<br />

agreement, with a view of purchasing<br />

long-term.”<br />

The SCO 1000 device requires 20W<br />

of electricity on average, equivalent<br />

to a small household lightbulb. Other<br />

comparable devices require circa<br />

7.5KW, close to 13 times the energy<br />

demanded. This low-power profile<br />

means devices can be operated using<br />

mobile batteries for up to four days.<br />

Around 40 SurfCleaner units have been<br />

installed in the oil-water separation<br />

segment, serving customers including<br />

the Swedish Coast Guard, Preem<br />

Refinery, Esso Refinery, Sonatrach<br />

Refinery, Exxon Mobil and Ports of<br />

Stockholm.<br />
