Your editor has just returned from a very exciting

trip to Arlington, Texas to attend the annual PAG

conference. You will see a summary of this

conference written up in this issue. It was an

outstanding one.

What impressed me most was the volunteer effort

of so many IOA members to make the conference a

success. Paul Overbeck assembled an outstanding

team with the result that this should be one of the

most successful regional conferences.

It is very gratifying to see good progress with the

various task forces. The Agri-Food Task Force and

the Air Treatment Task Force are now posting user

success studies on the IOA PAG website. This

website is rapidly becoming a valuable resource for

IOA members. I encourage you to visit the website

and see how it is developing.

Those who actually read Ozone News will have

noticed a typographical error in the last issue. On

page 10, in the Industry News section, the article

indicates that ozone was ineffective in inactivating

Cryptosporidiuim. The sentence should have

stated “ozone was effective in inactivating these

microorganisms whereby chlorine was not”. Thanks

to J. (Hans) van Leeuwen for pointing out this error.

Editor’s Notes

Disinfecting Mains with Ozonation

The September 2006 issue of AWWA’s Opflow magazinehas an article “Disinfecting Mains with Ozonation:Alternative Saves Time, Environment by Bruce Dammand Christopher R. Schulz.

In this process, a trailer-mounted ozone system allowsDenver Water field operators to disinfect mains and getthem on line in one trip. This system was first reported inOzone News Vol 33 No 3, p 10 (June 2005). The processwas a result of development by Denver and Camp,Dresser and McKee (CDM). A trailer mounted ozonesystem featured a 180 g/h Pacific Ozone TechnologyOzone Generator and a GDT system for gas dissolution.

The project started in 2003 with construction of thetrailer-mounted ozone system and has moved from fieldtrials to routine disinfection of water mains in thedistribution system. Due to the relatively short half life ofozone, a flow-through disinfection system is used. Excessdissolved ozone is removed by ascorbic acid. Denver hasfound that the effective limit for this process isapproximately 1000 ft of 12 in diameter pipe. Fortunately,most of the pipelines in the Denver distribution systemare 6 to 8 inches in diameter.

For more details, see AWWA Opflow, September 2006, pp18-21.

stated that the bromate incident in New York State isevidence that FDA does not adequately regulate thesafety of bottled water. The press release also claimedthat bottled water is regulated less stringently than tapwater. IBWA issued a statement that pointed out thefallacies in the press release. In 1999, the IBWA prepareda document, “Bottled Water D/DBP Resource Manual”,which educates the members on bromate and otherdisinfection byproducts.

New In Situ Oxidation Technology

Kerfoot Technologies, Inc. (KTI) announces anadvancement in in situ oxidation technology - its patentedPerozone® Modular System. Pulsed injection ofperoxide-coated ozone/air microbubbles treats solventand petroleum hydrocarbon spills in groundwater andsoil. Both saturated and unsaturated soils may be treatedin-situ, with site closure or barrier containment asrealizable goals.

According to Dr. William B. Kerfoot, President ofKerfoot Technologies, “This most cost-effective means oftreatment for heavily-contaminated sites, particularlythose with DNAPL, has experienced a cost of one-halfthat of other current processes. The combination ofozone and peroxide is the only chemox process, with itsbyproducts of water and oxygen when petroleumhydrocarbons are treated, as well as chlorides with thetreatment of chlorinated solvents, that has been approvedfor use in primary withdrawal regions of public watersupplies.”

KTI’s new Perozone® Modular System allows ozoneoutput ranging from .5 to 4.8 kilograms per day. It allowsuser choice of oxidative and air flow capacity, matched tosite needs. Control is achieved with either PLC or manualcontroller that can be linked to mass reductionmanagement programs. The Modular System may beinstalled in trailers, sheds, or negative-pressure isolatedrooms. The unique chemox Laminar Spargepoints®provide delivery of microbubbles with radii of influencefar exceeding conventional screened well points.

Bromate in Bottled Water

A New York State-based grocery retailer recently recalleda bottled water product that contained levels of bromatein excess of the FDA standard of quality of 10 μg/L (10ppb). The U.S. Food and Drug Administration districtoffice in Jamaica, New York is investigating the matter.The bottler, a member of IBWA (International BottledWater Association), has worked with the agencies andIBWA staff to ensure an appropriate response to thematter.

Also, another grocery retailer in Pennsylvania issued arecall of a bottled water product for bromate in excess of10 ppb. The Pennsylvania matter involves a differentbottling company, which is not an IBWA member.

IBWA is urging its members who use ozone as adisinfectant to be vigilant in monitoring bromide insource waters and bromate in post-ozonated sourcewaters (e.g., in tankers) and the finished product. Anactivist group issued a press release on August 28 which

Walkerton Clean Water Centre Provides

Drinking Water Professionals with

Training Needs

Following the tragedy in Walkerton in May 2000, theOntario government established a public inquiry andappointed Justice Dennis O’Connor to lead it.

Ten of the enquiry recommendations deal specificallywith training and certification of operators of drinkingwater systems.

In October 2004, the government of Ontario establishedthe Walkerton Clean Water Centre to coordinate anddeliver training programs to owners and operators ofdrinking water systems across the province. The Centrewas officially opened on May 31, 2005.

The Walkerton Clean Water Centre has identified a set ofhigh priority goals to guide its management andoperations, enabling it to move forward effectively andefficiently with its mandate.

The Walkerton Clean Water Centre’s primary focus is toensure that training, education and information isavailable and accessible to owners, operators andoperating authorities of Ontario’s drinking water systems,especially those serving small, remote communities,including First Nations. Flexibility in service, technologydemonstration, correspondence courses and onlinelearning will ensure access to operators from all overOntario. The Centre provides training courses that aremandated by the Ministry of the Environment, anddelivered by professional trainers experienced in thedrinking water industry. The Centre also delivers courseson advanced water treatment and advanced technologies


to provide operators and operating authorities with theinformation and education needed to operate broadwater treatment technologies used in the water treatmentsystems, and to provide them with information onemerging issues and challenges in the industry. A majormilestone was met when, in October 2005, the Centrebegan directly delivering training courses. As ofSeptember 1, 2006, more than 2700 individuals have beentrained.

An Interim Technology Demonstration Facility has beenestablished. The facility is to be used as a practicaltraining tool and an educational resource for watersystem owners, operators and the general public to makethem aware of the variety of treatment deliveries availableto them. Advanced water treatment technologies such asOzone, UV, and Membrane systems, with a fullyoperation laboratory are available to provide a useful tool


for training, technology demonstration, and research.The facility was opened in June 2006.

The Centre is committed to promoting research indrinking water quality. It works with leading drinkingwater experts on identifying and promoting research onwater quality issues.


The Centre awarded 3 scholarships to graduate studentsat three different universities in Ontario to contribute tothe advancement of research and technologydevelopment in the field of drinking water quality.

The Centre is sponsoring and participating in a researchproject in partnership with the Ministry of theEnvironment, and two universities in a study to“Investigate the Removal of Endocrine DisruptorsCompounds using Nanofiltration Membrane”.

The Walkerton Clean Water Centre has approvedsponsorship for the AWWARF research proposal “LowDose Risks from Bromate: The Relationship betweenDrinking Water Concentrations and the Actual Dose toSusceptible Organs in Rats and Humans”.

Case Study Summaries

Garlic Processing Plant – Spray Bar Rinse System

A garlic processor used to spray clove garlics withsolutions of sodium hypochlorite by means of a spraybar. Numerous maintenance problems were encounteredwith hypochlorite, including pitting of the stainless steelrollers, and the high total dissolved solids plugged thespray bar holes, corroding the feed pump and plumbing.Finally, sodium hypochlorite was leaving a residual in thewastewater pond, which is located directly over a sourcewater aquifer. Granular activated carbon (GAC)scrubbing of air was required, to remove and destroyodors from 100-125 ppm sodium hypochlorite solutions.Also, sodium hypochlorite reacts with organics, causing astrong ammonia odor, and has the potential for impartinga hypochlorite (or reaction product) residual on the plantproduct.

Replacement of the hypochlorite system by anozone/water system eliminated the maintenance costs ofhypochlorite, eliminated pitting and corrosion ofequipment, eliminated the need for BAC scrubbing ofodors, and lowered processing costs significantly. Otherapplications for aqueous ozone are being investigated atthis plant as a result.

Midwestern Food Processing Plant Chiller WaterTreatment for Reuse

Prior to installing ozone to treat 5,000 gallons of water ina chiller loop, the water had to be drained and the looprefilled anywhere between 1 to 7 days, due to excessivemicrobial contamination. Ozonation systems wereinstalled in several of the firm’s food processing plants,and the drain/refill time was extended to up to 6 months.Annual process water consumption prior to ozonetreatment was an estimated 1,123,000 gallons, but thathas been reduced to 72,000 gallons with ozonation. Laborcosts have been lowered, along with process downtime,since ozonation was installed.

Bulk Storage and Curing of Harvested Onions

Onions were stored in ozone-containing air (1~2.5 ppm)for many months, during which time “neck rot”(a fungus-caused disease) did not spread from the few infectedonions to other onions, thus extending the shelf life of theentire crop. A capital cost for ozone equipment of$116,000 (and negligible operation cost) resulted in anadditional income to the onion grower of $166,500 for thesingle crop stored. The equipment is being used onsubsequent crops.

Storage of Potatoes – Potato Grower (#1), Idaho Falls,Idaho, USA– 2003 Crop

Potatoes are harvested, and then a large percentage of thecrop is stored for future sales. Many harvested potatoesare infected with Phytophthora erythroseptica, or “PinkRot”, a fungus-causing disease that spreads rapidly touninfected potatoes, and these cannot be sold. Storage ofharvested potatoes under gaseous ozone does not curePink Rot on infected potatoes, but does prevent thespread of the infectious disease to other potatoes. Thisfarmer purchased a novel ozone treatment system to treathis 2003 potato crop, thereby saving much of his harvestfrom Pink Rot, and returning a financial benefit of$240,000 for that single year. The ozone equipment,which cost $116,000, is being used to increase themarketable output of subsequent potato crops by thisfarmer.

Ozone for Treatment and Storage of Grain – HarvestStates Amber Milling, Huron, OH, USA

Mold and bacteria in grain traditionally are addressed bythe use of chlorinated water. However, this techniquefrequently is inadequate for removing these harmfulmaterials allowing tempering bins, holding containers,and processing lines to become contaminated and have tobe cleaned. This requires complete shutdown of the plantand results in production and financial losses. Elevatedbacterial and mold counts sometimes cause final productsto fail to meet client microbial standards. Returnedshipments can cost up to $5,000 per rail car plusreprocessing costs. Chlorine also causes corrosion inmetal parts in the mixing and grain transfer equipmentand is a hazardous chemical to store and handle.Furthermore, chlorine chemically reacts with somematerials and organics, and the resulting chlorinatedcompounds sometimes remain in the final product ascontaminants. A project sponsored by the Electric PowerResearch Institute (EPRI) at Harvest States AmberMilling demonstrated that ozone and ultravioletradiation overcame the problems encountered withchlorine use, and resulted in significant cost savings to theplant as well.

traditional HVAC system. Almost immediately,complaints were received by management from visitorsabout tobacco odors. Installation of exhaust fans did notrectify the problem nor were complaints reduced. Ozonewas installed to treat in-duct air with great success. Notonly were tobacco odors eliminated, but total VOC levelsalso were reduced. An alternative technology, granularactivated carbon, which would have cost $25,000annually in replacement carbon, did not have to beinstalled. Ozone costs were $22,000 and resulted in lessmaintenance, less makeup air, and energy savings of$250/month.

The group also attended the IWA AOP4 conference, twoweeks after the Wasser Berlin conference. This conferencewas well attended with 182 attendees from 38 countries.EA3G will investigate the feasibility of participating inthis conference in the future.


IOA News (Cont’d)

A ozone/food conference will be held in June 2007 inValencia, Spain. Sydney, Australia wishes to host an IOAconference, and there are funds residing in Sydney tosupport this.

Currently, EA3G has 208 paid memberships.

Nippon Islands Group (JOA)

The 16th Annual Conference on Ozone Science &Technology was held on June 8-9 in Tokyo and was verysuccessful, with 230 in attendance. A second seminar isschedule in Tokyo on October 26-27.

Membership for NIG remains relatively stable at about130,

The NIG announced that the 19th Ozone WorldCongress will be held August 31- September 2, 2009 inTokyo, Japan including a technical tour to Kyoto.

Pan American Group (PAG)

The drop in membership has been stopped andmembership increased from 576 at the end of 2005 to 632.Several additional members have joined up as theyregistered for the Arlington Conference.

PAG presented a half-day session on ozone at the MarchWQY/Aquatech conference. Several similar sessions areplanned for 2007. PAG is investigating how to continuethe Ozone IV which was held in Fresno in 2005. The long-time organizer of the conference is no longer putting thison, leaving an opportunity for IOA to pick it up.

Relations with IUVA

Ongoing discussions are occurring on how IOA candevelop a long term relationship with IUVA and whatform this relationship will take. IOA is working veryclosely with IUVA on the planning for the Los AngelesWorld Congress

Bromate Research Proposal

AWWARF has authorized a research study to study thechemistry of bromate once it enters the human body. Thetotal project cost is $450,000. The IOA has agreed to

contribute $50,000 over a two-year period to this project.Prof. Gilbert Gordon will be the IOA liaison to thisproject.

Pan American Board Meeting

The Directors of the Pan American Group of theInternational Ozone Association held their semi-annualBoard meeting on September 17, 2006 in Arlington, Texasin conjunction with the PAG annual conference.Following are some highlights of the meeting.

PAG will face a $50,000 shortfall through 2007. This isdue to the sharing of the World Congress Income in 2007with three groups, and the lack of a PAG conference inthe same year. A membership dues increase is beingconsidered. PAG will need some outside support infunding the bromate project approved by theInternational Board.

All task forces (Municipal, Air Treatment, Agri-Food,Web) are active. Case studies are being developed forposting on the IOA webside. (See related article in thisissue). New officers were nominated by the Board and thenelected at a General Assembly of the PAG. These officerswill serve a three-year term, to be in line with the timingof the World Congresses.

On September 17-20, 2006, 252 attendees gathered at theWyndham Resort Hotel in Arlington, Texas for an IOAPan American Meeting, entitled “Ozone: DeliveringMultiple Benefits”. This was near a record number ofattendees for a Pan American Group meeting.

PAG Chairman Bob Jarnis opened the conference andwelcomed the attendees. He then introduced ArlingtonMayor, Dr. Robert Cluck.

Dr. Cluck also welcomed the attendees to Arlington. Asa medical doctor, he was familiar with ozone and its usein medical applications. He summarized the experience ofArlington and its water treatment with ozone andcommented on the noticeable improvement in their waterquality in the eyes of the consumer.

Bob Jarnis then reviewed the mission of the IOA and howozone is effective in response to a changing environment.The role of regulations on the fate of ozone, UV light andchlorine dioxide were summarized.

IOA International President Mike Dimitriou thensummarized the regulations affecting allowable bromatelimits in drinking water. The EPA is leaving the currentbromate level of 10μg/L while other research is beingconducted. He outlined the AWWARF research projecton bromate reactions in the human stomach. The IOA isproviding financial support for this research.

Blake Atkins, EPA Region 6 Chief

Blake Atkins, EPA Region 6 Chief then addressed thegroup. He summarized the EPA role in drinking waterquality and the Safe Drinking Water Act. Multiple threatsrequire a multiple barrier solution. It is necessary tobalance the threat of pathogens vs. disinfectionbyproducts. Mr. Atkins gave a very good summary of theadvantages of ozone along with concerns. Much workstill needs to be done to address problems with thedistribution systems, some of which are very old.

The opening session concluded with a utility panelconsisting of Frank Crumb, Fort Worth waterdepartment; Julie Hunt, Director of Utilities- Arlington;Bill Smith, Tarrent Water Authority; Charles Springer,Assistant Director of Operations, Dallas Water Utilities.They were asked to address the question “Why did youuse ozone?” and then “Is ozone expensive?”. Arlingtonreceived a big benefit in the reduction of consumercomplaints regarding taste and odor. They also saw areduction in treatment cost of $8/Mgal. Fort Worth sawlonger filter run times and less wash water required. TheDallas East Side plant had increased power consumption,but lowered costs of treatment chemicals. Overall, theyhad slightly increased costs but better water quality.

Technical Program

The technical program, held in cocurrent sessions, wasover two days and covered a wide range of technical andpractical topics.


Report from Arlington Conference

Joseph Huang, CDM, summarized the design,construction and startup of the ozone facilities at theDallas Water Utilities East Side Water Treatment Plant,the largest ozone generating facility in the world dedicatedto the treatment of drinking water.

Fumitake Nishimura, Ehime University, Japan, reportedon the applicability of ozone treated activated sludge forwastewater treatment which contains biorefractorymaterials.

Shane Snyder, Southern Nevada Water Authority,reported on preliminary work on the oxidation ofEndocrine Disrupting Chemicals and Pharmaceuticals inReuse water. Ozone treatment generally removes > 70%of the contaminants. Ozone plus hydrogen peroxide hasan increased initial reaction rate, but the final removalresult is the same as with ozone along. UV is insufficientfor most EDCs. Chlorine removes about 50%.

Past IOA President Joop Kruithof summarized the use ofUV/H2O2 for organic contaminant control and primarydisinfection for a Netherlands water supply. The situationwith bromates led them to the UV approach.

Jonathan Park, Gas Tran Systems, reported on ozonationof water using the Gas Tran unit as the contactor. Thiscontacting system uses a rotor to shear gas, and canhandle up to 250 gpm liquid. Mass transfer efficiencies of>90% were reported.

Akira Murai, The Kansai Electric Power Company,Japan, reported on the effects of nitrogen aiding theefficiency of ozone generator from pure oxygen feed gas.Argon gas as a “boost” provides a better generator

efficiency than nitrogen addition. This phenomena is nowwell known in the industry, but the reasons for the effectare still not completely understood.

Rip Rice and Chuck Sopher summarized successfulstudies using ozone to treat produce and in catfishprocessing. Henrik Steffens, Pacific Ozone Technology,gave a fascinating review of the uses of ozone in the wineindustry in the Americas. This session was an Ag-FoodForum and part of the activities of the Agri-Food TaskForce.

This is just a sampling of the papers presented. For moredetails, refer to the conference proceedings.

Technical Tours

Those remaining in Arlington on Wednesday visited twoarea water treatment plants, featuring ozone systems.

John F. Kubala WTP Ozone Generators

Dallas East Side WTP


The John F. Kubala Water Treatment Plant is designedfor 65 MGD, with room for expansion to 97 MGD.Ozone is added in two stages. A small amount of ozone isadded in the preozonation contactor for aid incoagulation /flocculation and for taste and odor control.1.5-3 mg/L ozone is added in the Intermediate Ozonecontactor for disinfection. The plant has (3) 980 lb/dayozone generators, produced by Ozonia, capable ofproducing 8-10% ozone. Feed gas is liquid oxygen, withsupplemental nitrogen injection.

The Dallas East Side Water Treatment plant is designedfor 550 MGD and has (9) 4000 lb/day ozone generatorssupplied by Wedeco, producing 8-10% ozone. Feed gas isoxygen produced by a BOC Gases vacuum swingadsorption plant. Ozone is introduced via fine bubbledome diffusers in the first three cells of the ozonecontactor.
