Editor’s Notes 

IOA members have a special opportunity this 

summer – attending the 19th World Congress and 

Exposition, Tokyo, Japan, August 31-September 9, 

2009. IOA World Congresses are held every two 

years, but in Japan only about every twelve years. 

The Nippon Islands Group of IOA and the Japan 

Ozone Association have been working hard to 

make this a memorable Congress. The technical 

program will consist of three parallel sessions with 

159 oral technical presentations and several poster 

presentations, from 17 countries. There will be four 

separate sessions with 22 presentations on medical 

applications. 

Attendees will have the option of devoting one 

afternoon to technical tours of one water treatment 

plant and one wastewater treatment plant that 

utilize ozone. A special technical tour is planned 

after the conference to visit water and wastewater 

treatment plants in the Kyoto area as well tour this 

remarkable city. 

For accompanying persons, there will be 

opportunity for sightseeing tours on each day of the 

conference. The organizers have selected the very 

nice Hotel Grand Palace, located close to Tokyo 

Imperial Palace and Gardens. There is convenient 

shuttle bus transportation from Tokyo’s Narita 

airport to the hotel. 

The conference is being held at Tower Hall 

Funabori. Funabori is very easily reached by 

subway, without any transfers, with a station 

located just outside the hotel; Tower Hall is also just 

next to the subway station. Japan IOA will have 

representatives at the hotel to help delegates 

negotiate the subway system. (We tried it last year, 

and it was very easy) 

A gala night is planned at the conclusion of the 

conference. This is sure to be a memorable 

occasion. 

Detailed information and a preliminary program for 

the Congress are enclosed in this issue of Ozone 

News. The most convenient way to register for the 

Page 5 

conference is online by assessing any IOA website 

(www.io3a.org, www.ioa-ea3g.org) I hope you can 

attend. You will find it a remarkable experience.

Emerging Contaminant Survey 

The EPA is seeking approval from the Office of 

Management and Budget to collect samples and conduct 

a survey of approximately 25 utilities to help determine 

to prevalence of about 200 emerging contaminants in 

drinking water. Improved chemical analyses will be used 

to detect many pharmaceuticals including antidepressants 

and for such substances as flame retardants showing up in 

wastewater. The water samples will also be tested for 

fluorinated compounds such as perfluorooctanoic acid 

(PFOA). PFOA is used in the manufacture of Teflon and 

has shown up in drinking water. For more information, 

refer to Federal Register, April 8, 2009, pp 15965-15967.

Mazzei Pipeline Flash Reactor 

Mazzei Injector Company announces the addition of its 

Pipeline Flash Reactor (PFR) for post-treatment 

aeration of pure-oxygen injection in wastewater treatment 

applications. The compact system utilizes a small 

sidestream passed through a patented Mazzei Injector to 

draw in ambient air or concentrated oxygen. The Aerated 

sidestream is delivered to the reactor where it 

aggressively mixes with the main flow, uniformly 

transferring the oxygen in the effluent pipeline. The PFR 

eliminates the need for post-treatment cascading systems 

or diffuser basins. It can also be utilized to dissolution of

Report from Boston Conference 

On May 3-6, 2009 some 322 delegates from 10 countries 

attended the joint International Ozone Association and 

International Ultraviolet Association Conference at the 

Hyatt Regency, Cambridge Massachusetts. This was the 

second joint conference between the IOA and IUVA, with 

the first being the Los Angeles World Congress in 2007. 

Page 10 

The hotel was an excellent venue, located on the Charles 

River. University rowers were practicing in the river each 

morning. For those exploring the city, the hotel was in a 

very central location. 

Paul Overbeck, Executive Director IOA and IUVA 

opened the conference and welcomed delegates and 

outlined the program. He thanked CDM for their 

sponsorship of the opening reception the evening before. 

Linda Gowman, IUVA president commented that IUVA is 

now 10 years old and has 525 members worldwide. She 

stressed the need for broader membership. There is a 

need to reduce carbon footprints. We do not yet know 

what delivering sustainable water means. 

Jeff Neemann, IOA President welcomed those attending 

an IOA conference for the first time. He thanked Paul 

Overbeck and Diana Schoenberg for their efforts in 

coordinating the conference. He stressed the need for 

volunteerism in our technical societies. He then had a 

hilarious cell phone “conversation” with President


Obama regarding the universal nature of ozone 

applications. 

Achim Reid, WEDECO, the Primary Sponsor of the 

conference also welcomed attendees and encouraged 

interaction between all to share experiences and 

expertise. 

Dan LaPrade of the Massachusetts Department of 

Environmental Protection summarized in a keynote 

address the use of ozone and UV in Massachusetts 

drinking water plants. Currently, 87% of MA water 

treatment plants use chlorine only, 16% use ozone. There 

currently is substantial interest in UV for disinfection. 

Wastewater plants may start using ozone or UV as they 

cannot switch to a dechlorination agent. There is a need 

for ozone and UV to be adapted to small systems. 

Frederick Laskey, Executive Director, Massachusetts 

Water Research Authority (MWRA) in a second keynote 

address summarized the history of the Boston Water 

Supply. MWRA is currently responsible for 220MGD 

drinking water (peak 350MGD) and 350 MGD 

wastewater (Peak 1200MGD). The authority currently 

Page 11 

has excess water due to reduced demand as a result of 

conservation and pricing. 

Boston was known as the dirtiest harbor in the USA. In 

2002 the $3.8 billion Boston Harbor Project, which 

reduced contamination of the harbor was completed. It is 

projected that Boston will have the cleanest urban 

beaches in the USA by 2011. 

The Carroll Water Treatment plant, utilizing ozone, was 

completed in 2005. The Authority saw immediate taste 

and odor improvements. In fact, in a nationally televised 

taste test between the Carroll water and bottled water, the 

Carroll water was preferred. Boston water is currently 

pharmaceutical free. 

The Authority is now working to comply with the LT2 

requirements for surface water. It is anticipated that UV 

will be used for a second stage disinfection. The project 

is expected to bid in 2011 and be completed in 2014.

Facility Tours 

There were two technical tour options for this conference. 

The ozone technical tour included the Walter J. Sullivan 

Water Purification Facility at the Cambridge Water 

Department and the MWRA John Carroll Water 

Treatment Plant. There was also an Ozone Operations 

Workshop at the Carroll WTP. 

The UV technical tour included the Brockton, MA 

Advanced Waste Water Treatment Plant and the 

Pawtucket, RI Water Treatment Plant.


The Sullivan facility is designed for 24MGD with 

capability to expand to 30MGD and was commissioned 

in 2001. The plant serves 100,000 people and has 

reservoirs for 8 months supply. The plant uses dissolved 

air floatation (in cold weather) intermediate ozonation 

and biological filtration. Ozone is supplied by (3) 400 

ppd oxygen fed generators (WEDECO), operated 

seasonally. Bromides are not an issue in this plant. 

The Carroll facility has a capacity of 465 MGD with 

average production of 270MGD. The plant produces 

unfiltered water into 7 new colored storage facilities. 

Ozone is used for primary disinfection. The plant was 

designed for 3 log giardia inactivation and 2 log 

cryptosporidium inactivation. Eventually UV will be 

needed for final disinfection. The plant has (4) 3380 

lb/day Fuji Ozone Generators producing 10% ozone from 

oxygen. In winter, half of the plant is shut down for 

maintenance. When UV is installed, the ozone dosage for 

giardia inactivation will be reduced. 

This plant, its design and layout was very impressive. The 

ozone generators are some of the largest manufactured.

Introduction 

The activated sludge process is the most widely utilized 

method for wastewater treatment process due to its 

relatively low cost and relative ease of operation. The 

generation of excess sludge is an inevitable result of the 

biochemical processing of organic waste by microbial 

agents in the activated sludge process. Generally the 

excess sludge produced from the conventional aerobic 

biological wastewater treatment process ranges from 0.2- 

0.4 kg excess solids/kg COD removed depending on the 

Solids Retention Time (SRT), oxic state and microbial 

species distribution in the treatment system. The 

associated power and chemicals costs for solids handling 

and eventual disposal can be significant and as much as 

40-60% of the costs of wastewater treatment are 

associated with the handling and disposal of excess solids 

(Tchobanoglous et al, 2003). 

Several factors have emerged which increase the 

likelihood that sludge costs will continue to increase. For 

instance restrictions on the availability of landfills (In 

Germany f.e. TASi 2001 (Verwaltungsvorschrift 

Technische Anleitung zur Verwendung, Behandlung und 

sonstigen Entsorgung von Siedlungsabfällen)), 

restrictions on the quality of biosolids used in land 

application and increasing citizen concerns over odor are 

causing sludge handling costs to increase. Recent 

regulatory pressures seem likely to increase the costs 

associated with sludge disposal. In the EU for instance, 

Abstract 

Although sludge ozonation in lab scale tests have tended to yield economic dosage rates in the regime of ≤ 0.1 kg O 3/kg SS 

removed, previous attempts to extend the approach to commercial scale installations have resulted in non-economical ozone 

dosage levels (Sievers et al, 2004; Yasui et al, 1996; Kobayashi et al, 2001; Sakai et al, 1997), requiring as much as 0.395 kg 

O 3 per kg SS removed (See Table 2). In this paper, we discuss a novel approach to sludge ozonation and report the results of 

full scale tests carried out at a 7 MGD (1100 m³/h) wastewater treatment facility which has been in operation since May 2006. 

A cost effective Ozone consumption value of 0.07 kg O 3/kg SS reduced was attained in the field, demonstrating the successful 

translation of bench scale type results to field applications using the Praxair approach.

while regulatory pronouncements like the Urban Waste 

Water Treatment Directive 91/271/EEC which requires 

that most of the EU populations be served by wastewater 

treatment facilities are leading to the generation of more 

excess sludge, other regulations like the Sewage Sludge 

Directive 86/278/EWG places restrictions on the 

agricultural application of sludge from the wastewater 

treatment process, while the landfill directive 

1999/31/EC effectively limits the disposal routes for 

excess sludge (Perez-Elvira et al, 2006). 

While the wastewater industry has traditionally focused 

on technologies that reduce the excess sludge generated 

at the back end of the wastewater treatment process, there 

has lately been a renewed interest in technologies focused 

on fundamentally reducing the generation of sludge in the 

aeration basin (WERF, 2004; Perez-Elvira et al, 2006). 

Overview - Sludge Ozonation 

Although several methods exist for achieving sludge 

minimization, the sludge ozonation process has been 

extensively studied and characterized, and has shown 

immense promise as a viable method for attaining 

consistent and reliable reduction of excess sludge (Yasui 

et al, 1996). The basic concept is the application of ozone 

to a side stream containing at a minimum, the equivalent 

portion of the excess sludge to be eliminated. The 

application of ozone to this stream causes the bacterial 

cells that come in contact with ozone to be lysed (Figure


1). Upon lysis, the cellular COD that is contained within 

the cells is leaked out, and the lysis products are then 

recycled back to the aeration basin where the bacteria 

feed on the released COD. The effective reduction in 

excess sludge is achieved when the COD generated from 

the lysed VSS (bacterial cells) is bio-oxidized in the 

aeration basin. The lysis COD when consumed, 

effectively generate a quantity of excess cells determined 

by the yield obtained within the wastewater treatment 

system. 

Figure 1. Principle of ozone lysis versus mineralization 

While the conceptual case for sludge ozonation and other 

lysis based approaches is straightforward, and a 

significant amount of work has been done both at the lab 

and field scales, the sludge ozonation process has been 

slow to be adopted, largely because the amounts of ozone 

required to effect the sludge reduction are uneconomical. 

Ozone consumption values required to achieve cell lysis 

have ranged from about 0.165-0.395 Kg O 3/Kg TS 

removed (Yasui et al, 1996; Ried et al, 2002). Although 

the economical range of ozone consumption will 

necessarily depend on localized costs for sludge handling 

and disposal, we estimate that the range of ozone 

consumption that will be viable will be in the regime of 

≤ 0.1 kg O 3/kg TS removed. The cost for sludge handling 

and disposal can vary between < € 80/dry t TS as a low 

cost range and > € 400dry t TS as a high cost range. The 

operational cost for generating 1 kg ozone using oxygen 

can be estimated as € 1 to 1.6. With an ozone 

consumption demand of 0.1 kg O 3/ kg TS removed, a 

total ozone demand of 100 kg ozone/ dry t TS is needed. 

This leads to operational costs of 100 to 160 €/dry ton TS. 

Previous studies have indicated the possibility that sludge 

Page 16 

ozonation can have a deleterious impact on several key 

operational parameters of the wastewater treatment 

process. Ried et al (2002) observed an increase in the 

effluent COD levels following sludge ozonation. Böhler 

& Siegrist (2004) have reported on the inhibition of 

nitrification and the improvement of denitrification 

observed during the sludge ozonation process. Raugust & 

Schwerdt (2004) reported about the possibility to 

completely eliminate filamental bacteria in the system. 

Bench Scale Tests 

Materials and Methods 

Prior to commencing pilot tests in the field, initial bench 

scales tests were carried out in a 1.5” diameter sludge 

ozone contact unit. The bench scale tests were undertaken 

in order to establish the effects of different contacting 

configurations on the ozone dosage requirements, lysis 

effect of ozone contacting, COD release associated with 

the lysis process as well as the correlation of the COD 

release with the extent of VSS degradation achieved and 

the biodegradability of the COD released as a result of the 

lysis process. 

Biodegradability was determined by comparing the 

oxygen uptake rates for the lysis products vs. a synthetic 

wastewater sample. Oxygen Uptake Rate (OUR) tests 

were carried out in a computerized N-CON Respirometer. 

Wastewater sludge samples were obtained from a 

municipal wastewater plant (Illinois, USA) with influent 

made up predominantly of sanitary wastewater. A 1L 

sample of synthetic wastewater was made up in distilled 

water by adding 16 g peptone, 11 g meat extract, 3 g 

Urea, 0.7 g NaCl, 0.4 g CaCl 2.2H 2O, 0.2 g MgSO 4.7H 2O, 

2.8 g K 2HPO 4. The resulting wastewater was then diluted 

as required. 

Full Scale Tests 

The Lariana WWTP (25,400 m 3/day; 10,000 kg/day COD 

removed – 2006 average) is located in Bulgarograsso 

(Como, Italy) and treats wastewater characterized by a 

predominant industrial (mainly textile) component: 62% 

as hydraulic flow rate and 75% as COD load during dry 

weather. The plant is a two-train aeration basin operation, 

with processes that includes an activated-sludge process 

for biological nitrogen removal (single sludge anoxic predenitrification 

- aerobic nitrification), followed by a sand 

filtration process for suspended solid removal, and final


effluent ozonation for the removal of color and 

surfactants. Prior to the commencement of the sludge 

ozonation process, all of the return activated sludge 

(RAS) was recycled to the anoxic pre-denitrification 

basin. The excess sludge is held in an aerobic holding 

tank and is then subsequently thickened and dewatered to 

about 19% dry solids content. The historical (2 year 

average) yield at the plant was 0.35 kg TS/kg COD 

removed. 

Figure 2. Generic schematic of the Praxair Sludge 

Ozonation Process 

Praxair’s sludge ozonation process Lyso TM comprises of 

an ozone supply system, a pump, and a gas liquid 

contacting system within which the sludge-ozone contact 

occurs (see Figure 2). The process requires that a portion 

of the RAS is passed through the sludge ozone contactor. 

System conditions are carefully controlled to ensure that 

an amount of ozone sufficient to implement the lysis of 

the bacterial cells is applied. An Allen Bradley SLC5/03 

PLC system was used to provide automatic control of the 

process. Ozone was generated from pure oxygen. A 3-4 

kg/h flow of a 7-8% w/w O 3 gas stream was applied to the 

portion of the RAS stream that flowed through the 

contactor. Because the primary RAS line at the 

Bulgarograsso plant is returned to an anoxic 

denitrification basin rather than to the nitrification basins, 

a separate RAS flow needed to be established for the 

sludge ozonation process as the high oxic state of the 

ozonated sludge implies that this stream cannot be 

directly returned to an anoxic basin. Ozonated sludge was 

returned to both nitrification basins. Detailed 

microbiological and respirometric analyses were 

undertaken throughout the tests.

Figure 4. Extended 30-hour OUR profile of municipal 

wastewater and lysis COD products 

An OUR baseline was determined by comparing the 

OUR of a synthetic wastewater containing an ideal 

nutrient mix with tap (blank) water (Figure 3). The 

endogenous respirometric rate for the sludge sample was 

determined from the OUR measurements obtained using 

the blank. Following the sludge ozonation process, lysis 

products were collected and the nutrient composition was 

analyzed (see Table 1). By comparing the relative 

proportions of Nitrogen and Phosphorus to the COD 

present in the lysis COD, it was determined that the 

nutrient composition of the lysis products was very 

similar to that of the idealized synthetic wastewater.

influent, lysis products and synthetic wastewater formulations. Lysis products are derived from samples. 

Figure 4 above summarizes the results of the 

biodegradability tests that were run on the lysis products. 

The OUR results confirm the high biodegradability of the 

lysis product. 

Full Scale Tests 

Prior to the commencement of the sludge ozonation 

process, a comprehensive baselining study was 

undertaken during which the process conditions at the 

plant were measured and compared to the historical plant 

data. Broad agreement was observed between the results 

of the baselining exercise and the historical plant data. A 

plant wide biosolids inventory had also been established 

prior to the commencement of the tests, and a critical 

control feature was to maintain this solids inventory at 

constant levels in order to facilitate accurate accounting 

for the fate of the solids in the process. Solids inventory 

was therefore maintained at 80,000 kg and the extent of 

sludge reduction achieved was obtained by closing the 

solids balance. It was already established from the 

analysis of the previous 2 year operating data at the plant 

that the average yield was 0.35kg TS/kg COD removed. 

The current levels of sludge generation were compared 

against this historical baseline to determine the extent of 

sludge reduction achieved. 

Discussion 

The pilot test was carried out at a scale that was designed 

to allow for the effective treatment of up to 40% of the 

excess sludge. Praxair’s approach to sludge ozonation 

differs from previous methods in its high selectivity 

(Fabiyi & Novak, 2007) derived largely from the use of a 

plug flow approach that maximizes the use of ozone for 

cell lysis rather than wasteful consumption of ozone by 

the chemical oxidation of the lysis products. Our 

approach uses multiple injection loops for bringing the 

sludge and the ozone rich gas stream in contact. The 

Page 18 

ozone consumption observed during the tests was 

approximately 0.07 kg of O 3 per kg TSS reduced. Table 2 

provides a comparative summary of the ozone 

consumption values obtained during this study and other 

results from the literature. 

Table 2. Comparative table of specific ozone 

consumption and the corresponding sludge reduction 

(derived from Sievers et al, 2004). 

We observed significant reduction of foaming in the 

aeration basin process of the wastewater treatment 

operation as a result of the ozonation process. Prior to the 

commencement of the ozonation process, there was a 

persistent 20 cm foam layer at the top of the aeration 

basin causing solids to be frequently purged from the 

surface of the aeration tank and sent directly to an aerobic 

sludge holding tank that is connected to the aeration basin 

through an overflow weir. Following the commencement 

of the ozonation process, there was a significant 

reduction in the population of all filamentous microbial 

species, with the most significant reductions being 

observed in Microthrix parvicella and Nocardia species 

(see Figure 5). The impact of the sludge ozonation 

process on filamentous organisms was rapid and there 

was an effective control of the foaming within the first 

three weeks of operations. 

Although previous studies (e.g., Ried et al, 2002) had 

indicated that there was a slight increase in the effluent 

COD during sludge ozonation, our bench scale tests

the incidence of filamentous bacterial species

removal. Solid black vertical line indicates

tests. 

suggested that the lysis products were sufficiently 

biodegradable and could be effectively removed in the 

aeration basin. Throughout the test period (May 2006 to 

March 2007) COD removal efficiency was maintained at 

the historical average of 80%. TN removal efficiency was 

also maintained at the historical pre-ozonation average 

level of 60% (See Figure 6 and Table 3). It is possible that 

the higher effluent COD levels that were observed in the 

Page 19 

effluent could have been due to the lack of supplemental 

oxygen to use in the bio-oxidation of the lysis products in 

the basin. It should be noted that the concentration of 

ozone in most generators would typically be in the range 

of 7-14% w/w Ozone, with the rest of the stream being 

made up of pure oxygen. While previous methods viewed 

this ‘excess oxygen’ stream as a waste gas, our approach 

permits the dissolution of this ‘excess oxygen’. There is 

sufficient oxygen in this stream to provide all of the 

supplemental oxygen required for the oxidation of the 

lysis COD products in the basin. During the pilot, the 

residual DO level in the basin went from a value of about 

1 mg/L to 2-3 mg/L following the commencement of the 

sludge ozonation process. It is conceivable that in 

addition to the benefits of reduced sludge handling and 

disposal costs, aeration power savings could be achieved 

in plants that have turn down capacity on their blowers 

based on the supplemental oxygen gains from the sludge 

ozonation process. 

The impact of sludge ozonation on excess sludge 

generation occurs rapidly and net changes in the trends 

for sludge generation can be observed within a few weeks 

of operations (Figure 7). 

Figure 7. Trends in cumulative excess sludge production, 

before (weeks 17-21) and after (weeks 21-30) partial 

sludge recycle ozonation. 

Conclusion 

Ozonation of sludge is an effective method for achieving 

a reduction in excess sludge generated in the activated 

sludge process. It is possible using a high selectivity 

reactor to achieve economical levels of ozone 

consumption that make sludge ozonation a commercial 

viable approach for sludge minimization.


Results from our study indicate that sludge ozonation had 

no effect on the nitrification efficiency during full scale 

applications (Vergine et al, 2007) confirming the 

observations of other groups (e.g., Lebrun et al (2006), 

Raugust & Schwerdt (2004)). Our studies indicate that 

the COD released during the lysis process is highly 

biodegradable. 

When optimally operated, the sludge ozonation process 

enables the realization of economical dosages and 

consumption levels of ozone in field tests. We did not 

observe a reduction in the COD and TN removal 

efficiencies at the plant, a result which was in agreement 

with the observations made at the bench scale regarding 

the very high biodegradability of the lysis products. Our 

experience also indicates that sludge ozonation can 

provide an effective means for biological foaming and 

bulking control in wastewater treatment operations. 

The sludge ozonation process has been successfully 

applied for sludge reduction at a municipal wastewater 

treatment plant that handles some textile wastewater as 

well. The following results have been obtained (i) Sludge 

reduction up to 60% (ii) Elimination of foaming 

problems (iii) Improvement in process stability (iv) 

Improvement of dewatering (v) Improvement of settling 

(vi) Improvement of effluent quality (vii) Effective COD 

removal.

2010. 

The aim of this Symposium is to offer an appropriate and fruitful framework for sharing experiences, 

scientific ideas and addressing current advances in the use of ozone and the environmental subjects. All 

this will contribute to strengthen even more our ties of friendship and cooperation. For this reason, we 

invite all specialists, from all over the world, to present their papers in this congress or to participate only 

as delegates. 

A broad scientific program has been organized with the topics tackled at present by our Center as well as 

those developed in collaboration with other Cuban institutions during these 30 years of scientific work. 

The main subjects in the Symposium will be: Ozone Experimental Medicine and Medical 

Treatments; Ozone Chemistry; Ozonized Vegetable Oils; Ozone in Food Industry; Treatment of 

Water, Waste Water and Solid Wastes; Environmental Management; Renewable Energy and 

Ozone Generation System Design. 

All work sessions will comprise lectures, oral presentations and posters (75 x 120 cm). 

With the aim to achieve a broad promotion of the papers, persons that are interested to participate must 

submit abstracts (with no more than 250 words) in English language, which includes the title of the 

paper, author's name(s), institution, city and country where the work was carried out. The author who 

presents the work should be marked with an asterisk (*). The deadline 

for the presentation of the abstracts will be March 31 ST , 2010.

Preliminary Congress Description 

� � � � � � � � � � 

1. Purpose 

Today, throughout the world, ozonation technologies have been widely used to establish the safe and comfortable life 

and production process in high-technology industry. This is because ozone has a strong oxidation capacity, no harmful 

residues after its decomposition, easy management and control characteristics. Accordingly, the ozonation technologies 

are greatly expected to play an important role in a wide variety of industries in future. 

Meanwhile, in Japan, ozonation technologies have been also widely used to get tasty and safe drinking water, and 

expected to be improved for more effective and new capacity in water purification plants. Gradually, they have been 

also applied to spa, pool and aquarium for clear water, agriculture, food and beverage for disinfection and high 

technology production plant for clean-up. Additionally, they are expected to be adopted more in sewage and wastewater 

treatment field for water environment preservation and reuse of the treated wastewater. 

The Ozone World Congress is held biennially, where researchers, engineers, consultants, and people concerned gather 

from all over the world for presentations and discussions of the results from their researches and experiences. Through 

the Ozone World Congress, all participants can get up-to-date information, knowledge and innovative ideas, surely 

contributing to the development of ozone science and technology. 

It will be the third time for Japan to hold the Ozone World Congress in 2009, including the 7 th congress (Tokyo, 1985) 

and the 13 th congress (Kyoto, 1997). This congress should be a good opportunity to get up-to-date information of the 

science and technology developed in Japan as well as all over the world.
