Unless the wateris filtered immediately before use with anadvanced technology like ultrafiltration (UF)membranes there is no way to know for sure.Whether a home is on city or well water, harmfulor undesirable contaminants could be flowingfrom faucets every day that you cannot see ortaste. Unfortunately, throughout the world evenwith stringent national and local regulations, anddue diligence by water utilities, microbiologicalcontamination in water supplies is a reality. Oldand deteriorating water pipes and city watermain breaks can contaminate water before itreaches a home. Private wells can becomecontaminated at any time. Without constantself-monitoring of a well, there is no way toknow when this happens. Due to the increasedpublicity consumers worldwide realize the needto be more vigilant about the quality of waterthey are consuming.Rik Schuurman The private Germanbrewery Ustersbach chose PENTAIRProcess Technology’s turnkey BeerMembrane Filtration (BMF) installationto upgrade the brewery’s beer filtrationsystem.Pentair Process Technology will install a turnkey stateof-the-artbeer filtration installation that includes oneBMF-18 skid with a possible second BMF skid in thefuture. The brewery is integrating the expansioninto the existing filter room. The completion of theproject is scheduled for fall 2011.Started in 1605 as a family business, Ustersbach is nowa renowned brewery with a diverse product line. Thebrewery produces nine different beers including pilsner,pale beer, wheat beer, and strong beer, alongwith a selection of soft drinks. All beers use mainlylocal products, without pasteurization and in thetradition relating to crafts following the Bavarianpurity requirement of 1516.German breweryUstersbach to installPentair BMF system“The diatomaceous earth-free beer filtration isgaining ground in the beer industry and we areconvinced that Pentair’s BMF system is in linewith our ambition to produce beer of the highestquality according to our family recipes whileusing modern, efficient and environmentfriendlytechniques,” said Stephanie Schmid,owner of brewery Ustersbach.Dick Meijer, Pentair Process Technology’sCommercial Director - Beverage, added, “Thisillustrates our capacity to preparebreweries of all sizes forthe future. Our BMF installation’sdesign enables breweriesto do more with less while focusingon the key elements of thecentury-old beer tradition ofquality, innovation, care for theenvironment, and sustainability.”The Water Quality Association’s leadership isworking to encourage U.S. officials to understandthat the most practical solution to water relatedissues is to integrate point-of-use (POU) into thecurrent regulatory paradigm. “Our goal is toadvance the understanding of policy makersabout final barrier treatment of drinking,” saidPeter Censky, executive director of WQA. “Webegin with a premise that within 20 years thecurrent paradigm – centrally treating water anddoing essentially nothing more – will no longerwork. Central treatment will not be able to copewith the demand for higher quality water.”Certified purification you can rely onPentair’s H2OK WaterPurifiers, which use PentairX-Flow UF membrane technology, are one of thefew POU drinking water products available in theworld certified by the Water Quality Association(WQA) to retain 99.99 percent of viruses and cystsand 99.9999 percent of bacteria.

Whenchoosing an in-home water treatment system, itis important to know that all POU filtrationproducts are not the same. To ensure the safest,highest quality water possible, you should choosea filter that is certified to protect against viruses,cysts and bacteria, and removes chemicalcontaminants while delivering great-tasting,odor-free water The Pentair WaterPurifier + thatcombines UF membranes and activated carbonprovides this complete protection.“Pentair H2OK WaterPurifiers are well positionedagainst other POU technologies on the market,”van de Ven said. “Overall, UF is an excellent andsustainable way to eliminate the uncertainty ofmicrobiological outbreaks and ensure consistentdelivery of high-quality water, without electricityor wasted water that other technologiesrequire.”4 5K n o w H o w I 2 0 1 1 I 1 K n o w H o w I 2 0 1 1 I 1

B E V E R A G EDouble DutyGuinness Anchor Berhad: Retrofitting with LiquiVapincreases CO 2recovery yield and lowers costsRoy SpeeApproximately 60 percent of the costs associated with carbondioxide (CO 2) recovery are attributable to the cooling stage of the process.If less energy is required for cooling, it translates to a reduction in runningcosts. This is precisely what the LiquiVap system from PENTAIR Haffmans“This idea was very convincing, since the existingplants were also manufactured by PentairHaffmans,” Chuah Chong Sheng recalled. “Wewere already familiar with the products they arecapable of delivering and also the high level ofsystem as well as its maintenance costs are certainlynot the least of these advantages, whichalso include increased reliability.Optimal energy efficiency all of the timewith a LiquiVap unit and the installation of thelatest control system, the entire final stage ofCO 2treatment was redesigned.

The next generationXIGA will be launched in thesecond half of this year.”Jürgen von Hollen, Managing Director Pentair X-Flow,Head of Water - Pentair Clean Process TechnologiesXIGA - the membrane of choice around the globeSwedish water treatment plant to utilize XIGAXIGA to be used in Singapore drinking water projectAbu Dhabian wastewater polishing plant to be equipped with XIGAA three-phase project in Gothenburg, Sweden toincrease production capabilities of purifying surfacewater to drinking water will use PentairX-Flow’s ultrafiltration (UF) technology.Gothenburg, the second largest city in the country,is located on the west coast of Sweden. Thecity’s water treatment facility must supply approximately500,000 consumers with drinking waterusing surface water and river water from the Götaälv (Gota River).The three phases of the project will increasewater production to meet demand and high qualitystandards. Phase one will produce 1,800 m 3 /hby 2013, Phase two, 3,600 m 3 /h in 2015, and Phasethree, 7,000 m 3 /h in 2017. In the first phase of theproject, a UF plant with four Pentair X-Flow skids,each equipped with 36 pressure vessels containingXIGA UF membranes, will be installed in an existingwater production plant. By the end of Phasethree, 16 skids will be installed. Pentair X-Flow haspartnered with Purac, a prestigious Swedish contractingfirm, for this project.In the treatment process surface water is coagulatedand, after settling, sent through granularactivated carbon filters. The output of the carbonfilters is transferred through the UF membranesystem.The membranes remove all fine siltand turbidity (suspended particles)and create a hygienic barrier for bacteria, virusesand other microorganisms. The XIGA configurationconsists of multiple membranes installed inhorizontal pressure housings. These membranesproduce the highest quality water.Pentair Water Asia Pacific will supply PentairX-Flow’s XIGA ultrafiltration (UF) membranes tothe Lower Seletar Waterworks project inSingapore to be constructed by SembawangEngineers and Constructors (Sembawang), one ofthe leading engineering and construction companiesin Southeast Asia.Once constructed, with a capacity to process 300 MLDof raw water into drinking water, the Lower SeletarWaterworks will be one of the largest drinking waterplants in Singapore that utilizes UF at the front of itstreatment process. It is also the first drinking waterplant in Singapore to use a pressurized UF membranesystem.Pentair X-Flow XIGA UF membranes are widely usedthroughout the world for large-scale drinking waterproduction and effluent reuse. They are horizontallymounted membranes housed in pressure vessels.The pressure vessels are stacked on a skid to reduce thefootprint, which makes Pentair X-Flow’s XIGA UF membranesystem well suited for the Lower Seletar plant’slimited footprint. In addition, the absolute pore size ofXIGA membranes ranges from 0.025 to 0.030 micronsmaking XIGA one of the tightest in its class. This enableshigh log removal for both bacteria and viruses.“The use of XIGA membranes for drinking waterproduction could potentially reduce the cost ofdownstream disinfection and provide cost savings forthe end-user,” explained Duane Schlicht, ManagingDirector Pentair Water Asia Pacific.Singapore is a land-scarce countrywith limited water resources. As such,the nation has long recognized the importance ofdeveloping and maximizing its water resources tosustain its economic growth and modern lifestyleof its citizens. PUB, the nation’s water authority,has initiated many internationally renowned projectsincluding NEWater factories, the Tuas desalinationplant and the Marina Barrage (for urbanwater collection). With its aim of becoming one ofthe world’s hydro hubs, Singapore always welcomesand embraces the use of advanced waterpurification technology in its quest to increase thenation’s water supply and improve its water security.The selection of Pentair X-Flow’s XIGA UFmembranes for drinking water production at theLower Seletar plant bears further testament tothe high quality and reliability of Pentair X-Flowmembrane products.Pentair X-Flow supplies XIGA membranes to theengineering firm Boustead Salcon Water Solutionsfor wastewater treatment for reuse at the AbuDhabi Sewerage Services Company’s (ADSSC) AlWathba Enhanced Treated Sewage Effluent (TSE)Treatment Project. The new wastewater recyclingplant is the first of its kind in the United ArabEmirates (UAE) and has a capacity of approximately27,712 m 3 (6 million gallons) per day.The UAE depends on desalination tosupply water. By focusing on wastewaterreuse, the UAE is responding to the need toensure security for its long-term water supply. In2010, Abu Dhabi introduced new wastewaterregulations, and by doing so the Emirate establisheditself as the regional leader in the waterreuse sector.In addition to the ultrafiltration (UF) polishing ofthe TSE, the plant includes a strainer and ultravioletprotection processes. An estimated 95 percentof the TSE supplied to the plant will berecycled and recovered. This water is used foragricultural irrigation and horizontal landscaping.The Al Wathba TSE polishing plant is important insetting the trend in the UAE for wastewater treatmentusing UF membranes for tertiary filtrationof treated sewage. This technology provides acredible and proven alternative to the desalinationof seawater for non-potable applications. Bysupplying UF technology to the ADSSC’s AlWathba plant, Pentair X-Flow reinforces its positionas the UF market leader in the Middle East.8 9K n o w H o w I 2 0 1 1 I 1 K n o w H o w I 2 0 1 1 I 1

The compact andtested modular design of the pumprooms provides a very efficientsolution. Such a complete supplyconsiderably reduces the risk ofassembly errors and saves constructiontime on site. Ferrostaal,an organization with 60 officesworldwide, recognized theseimportant ad-vantages.Firefighting pump room protectsgas and oil plant“One pump room was installed for the end customerOMV Petrom S.A. at its new gas compressorstation in Bulbuceni, Romania,” said Nielsvan den Hurk, Pentair Nijhuis’ area sales manager.“Petrom is the largest corporation inRomania and the largest gas and oil producer inEastern Europe. From Bulbuceni, Petrom providescompressed gas to the national gas network.”The pump room in Bulbuceni needed to meet Petrom’ssafety requirements and strict sound reductiondemands to protect personnel and the work area.Since the equipment is tested weekly, part ofmeeting these guidelines included insulating thepump room so that the sound level from one metermeasures less than 85 dBA.In addition to the customer’s requirements, a numberof extreme conditions that are decisive factorsfor selecting the proper diesel engine were takeninto account for the pump room design. Theseconditions are: the site is located at 208 meters(682 feet) above sea level, the surroundings temperaturevaries between minus 29 and 40 degreesCelsius (minus 20 and 104 degrees Fahrenheit) andthe average relative humidity is 63 percent. Thepump room, consisting of four pumps and twojockey pumps –that serve to maintain water pressurein the sprinkler system–, provides the completewater supply for fire protection at this location.“The pump room was designed according to the latestdirectives of the National Fire ProtectionAssociation’s (NFPA) international standard NFPA-20,” van den Hurk said. “Besides that I am proud tosay that we were able to meet all extra requirements,even though the conditions were challenging.”New power plant in Venezuela protected against fireThe end customer of the second pump room, C.A.Energía Eléctrica de Venezuela (Enelven), built twocombined cycle power plants in Zulia state, Venezuela.These power plants will supply sufficient energy tomeet the energy demand of the entire region.“The EPCC of this project, Ferrostaal, initially contactedPentair Nijhuis to supply separate firefightingpumps at the location in Bachaquero,” van den Hurksaid. “But, considering the remote location, theychose the containerized pump room option, and thusprofit from the advantages of this solution.”The pump room contains two firefighting pumps, onediesel driven, one electric driven pump, and onejockey pump. All pumps comply with the latest regulationsof NFPA-20, and are Factory Mutual (FM)approved. In addition, extra devices, supplied by thecustomer, were successfully incorporated into the totalcontainerized concept.“Constructing containerized units requires expertisethat is available within Pentair Nijhuis,” van den Hurksaid. “The firefighting equipment at both Petrom andEnelven well prepares both locations in the event of afire.

The upgrading technologyrecovers 100 percent of the CH 4and causes noCH 4losses. In the process the biogas is firstcleaned by a Norit activated carbon filter andthen the cleaned biogas flows through a membraneinstallation and a CO 2recovery system.The biomethane produced by the upgradingsystem has the same specifications as naturalgas and has been accepted by Enexis for injectingit into the national gas grid. Enexis isresponsible for the development, construction,maintenance and management of thegas and energy distribution network. As suchthe company is the link between 2.6 millioncustomers and the energy suppliers.The recovered CO 2has a high purity and canbe used as CO 2gas in greenhouses or liquefiedand stored for use in the food and beverageindustries.Pentair Nijhuis is member of a pilot group of organizations that havestarted the implementation of this NEN directive. During the introductionseminar on December 9, practical experiences with the applicationof ISO 26000 in business and industry were presented. PentairNijhuis’ Managing Director Robert Schuuring was one of the speakers.“ISO 26000 is well suited to Pentair Nijhuis,” he said. “Our productsrepresent quality, high efficiency and durability. We use ISO 26000 asa guide to integrate social responsibility into our values and practices.We are taking an even more critical look at our purchase and productionprocesses and the social environment. ISO 26000 presents a verygood approach in doing so.”14 15K n o w H o w I 2 0 1 1 I 1 K n o w H o w I 2 0 1 1 I 1

w o r l d w i d eQuick service,happy dolphinsPentair X-Flow wins 2011iF Product Design AwardPentair X-Flow’s Airlift MBR Megablock, was honoredby the International Forum Design (iF) for excellence inproduct design. In total, 2,756 products from 1,121 participantscompeted for this prestigious design award.Winning the award confirms that pentair X-Flow’sexpertise in combining state-of-art technology withappealing design features.The iF Product Design Awards are prestigious awards that recognizemanufacturers and designers of industrial products exhibitingsuperior design from around the world in a variety ofcategories. Selection criteria include the quality of design, functionality,degree of innovation, simplicity of operation, andenvironmental impact. The Pentair Megablock is used in municipalwastewater treatment.Prompt action by the Pentair Nijhuisservice team prevented a major disruptionat the Dolfinarium, a dolphintheme park in Münster, Germany. Twopump rooms at the facility were floodeddue to a water pipe leak. The leakwas repaired and the pump roomswere drained, but the pumps neededto be repaired and restarted to maintainthe water in the pool where thedolphins and other sea animals live.This had to be done quickly to avoidthe need to move the animals 300 kmto the Dolfinarium in Harderwijk, theNetherlands. Thanks to Pentair Nijhuis’experienced service team the pumpswere started up in time and the movewas not necessary. A well earned“thank you” was the result.Specifically it is the sludge separating component of large-scale MembraneBioReactor (MBR) systems. The compact membrane separation system withinthe Megablock produces crystal-clear, bacteria-free water from a biologicalwastewater treatment process that can be reused for a variety of purposes.In addition, the membranes are in a dry and clean environment makingthem quickly accessible without comprising the health and safety of plantworkers.iF praised the Megablock for its “Lego-Style” modular design that allowsfor easy installation and system expansion. Its advanced component designimproves fluid flow and aeration, resulting in unprecedented performance.“The Efficient Performance Technology philosophy - our guiding principle inproduct development - led to the Megablock’s development,” said RickRosberg, Global Commercial Director of Pentair X-Flow. “A compact, modulardesign flows naturally from our ambition to do more with less.”KnowHow Published byPentair Water ProcesTechnologie Holding BVP.O.
