Our state-of-the-art technology helps to quench this fundamental humanneed, even when the source water is less than optimal.

Hampton Advanced WaterTreatment Works LONDON, UNITED KINGDOM

Hampton AdvancedWater Treatment Works(AWTW) is one of themost technologicallyadvanced of its kind.It is London’s largestwater treatment plantwith a design capacityof 790,000 m³/day.

Owned by Thames Water, it has a key role as thecontrol centre for the Thames Water Ring Main, thebiggest single trunk water distribution system in theUnited Kingdom. The works was originally built in the1850s and the site includes old Victorian buildings,filter beds and some larger water storage beds. ThamesWater has made several large investments in the works,particularly with the introduction of Granular ActivatedCarbon within the Slow Sand Filters. The completion ofa capital investment program in 1998 led to significantimprovements. Hampton AWTW provides some of thehighest quality drinking water in the world.

On arrival at Hampton, the stored water is fed intoan on-site reservoir called the Grand Junction. This smallreservoir is predominantly used to blend differentsource water and balance the flow into the works.There are 32 dual cell filters on site acting as roughingrapid gravity filters before the slow sand filtrationprocess on site. ITT supplied Leopold filter underdrains,together with the main air scour delivery piping andsupervision of installation and training services to thecontractor Black & Veatch. The filters were redesignedin conjunction with ITT to maximize the availableunderdrain area.

The water is filtered through Primary Rapid GravityFilters. These filters function in biological mode withno coagulant dose applied. The filters are designedpurely to reduce the load from large reservoir algae andthus to lengthen Slow Sand Filter bed run duration. Thewater from the primaries gravitates under the GrandJunction Reservoir into the K-Shaft, where six pumpslift the water into the Ozone Plant. Most of the SlowSand Filters contain a layer of granular activated carbon(GAC, for pesticide reduction) within the sand bed. TheSlow Sand Filters are skimmed according to time orhead-loss data. Filtrate water is then directed by lowlift pumps from the Slow Sand Filters to the disinfectionstage. The water is dosed with chlorine prior to the finemicro screens and then flows into the contact tank fordisinfection. After disinfection, the water is sulphonatedand then ammoniated, prior to being passed intosupply with a combined monochloramine residual.

Next door to the works are two officially designatedwildlife preserves, the Sunnyside Reservoir and the StainHill Reservoirs, which contain flower-rich grassland andhabitats for water birds. The Hamptons AWTW welldemonstrates the successful accommodation of natureconservation with operational considerations.

HENDERSON,NEVADA, USAHenderson, Nevada, asuburb of Las Vegas, islocated between LakeMead and Las Vegas inSouthwestern Nevada,USA. Henderson is thesite of two of the largest

water treatment facilities operated by the SouthwesternNevada Water Authority (SNWA). Both facilities, theAlfred Merritt Smith and the River Mountains WaterTreatment Plants are direct filtration plants. The directfiltration process consists of adding a coagulant to thesource water before deep bed dual media filtration anddisinfection. The source water for both facilities isderived from Lake Mead, which is the impoundmentbehind Hoover Dam. Originally the Alfred Merritt SmithWater Treatment Plant was constructed in the 1970son the shore of Lake Mead at a capacity of 650 MGD(2.46 million m³/day). As the region continued togrow, the River Mountains Water Treatment Plant wasconstructed away from Lake Mead in the late 1990s.The final total capacity for both plants is 1.25 billiongallons per day (4.73 million m³/day). ITT providedboth plants with the Leopold filter underdrains, filtermedia and air header piping.

BOGOTA, COLOMBIAThe Francisco WeisnerWater Treatment Plantin Bogota, Colombiaconsists of 16 dual bayswith 32 filters, a total of45,066 square feet. Formany years, the planthad been operating

utilizing clay underdrains as its filter bottoms. ITT wasselected to rehabilitate the plant with its Leopold filterunderdrains and IMS cap. ITT also added air headerpiping to support the new air/water backwash system,which has increased the plant’s efficiency. The air/waterbackwash employs an upflow water wash includingair scour with full bed fluidization. Combined witha low rate backwash, air scour is the most effectiveway to remove solids from a filter by providing veryeffective cleaning action as the result of higher shearforces in the media bed and abrasion between grains.As a result of the new system, the Weisner plant isnow experiencing a savings of 40 percent of itsbackwash water, as well as more than 25 percentincrease in filtration without sacrificing water quality.

LAKE PLEASANT,PHOENIX, ARIZONA, USAPhase one of the LakePleasant Water TreatmentPlant uses water from theCentral Arizona Projects’Waddell Canal and hasa capacity of 302,800m³/day (80 MGD). At the

time of its launch, the award-winning project was thelargest potable water design-build-operate project inNorth America. The treatment plant has to deal witha wide variation in the feedwater quality and uses anarray of advanced technologies to treat the water tomeet or surpass regulatory requirements. The processconsists of ballasted-floc clarification, ozone oxidation,deep-bed anthracite filtration, deep-bed granularactivated carbon adsorption, and UV disinfection. ITTsupplied the 16 Leopold deep-bed anthracite filtersand the 16 Leopold deep-bed granular activated carboncontactors. Long-term climate change is threateningthe viability of life in the dessert, making the LakePleasant Water Treatment Plant an additional resourcefor providing water to the people of Phoenix, AZ.

SONGJEON WATERTREATMENT PLANT,WONJU, KOREAThe Songjeon WaterTreatment Plant, operatedby the Korean WaterResources Corp, obtainsraw water from theHoeng-Seong Lake.

The water contains seasonal algae blooms. And afterrainfall the water’s turbidity* and organic contentincrease significantly. Earlier, the algae were removedby using copper based products, which made thewater taste and smell bad. Furthermore, the plant’sdisinfection practices led to carcinogenic chlorinatedorganic by-products. The new system is designed tohandle 100,000 m³ of water per day in a variety ofconditions. It includes a pre-sedimentation basin,a Leopold DAF system, as well as gravity filters withunderdrain, IMS (Integral Media Support) cap, sandand anthracite media, and backwash troughs. Thepre-sedimentation basin allows the turbidity tosettle prior to treatment. The DAF removes the algaewithout the use of copper, which significantly improvessmell and taste. It also eliminates more organiccompounds than conventional clarification, andreduces the amount of chlorinated organic by-products to 65 percent below the criteria mandatedin Korea and the United States.

*turbidity: the cloudiness or haziness of a fluid causedby particles that are invisible to the naked eye.

GOLD COAST,QUEENSLAND, AUSTRALIAITT was contractedto supply a LeopoldDesalination PretreatmentSystem to QueenslandAustralia. As part of theGold Coast DesalinationProject, the first large

scale desalination plant on Australia’s easternseaboard, ITT supplied 18 Leopold filters, totaling2,147 m², to pretreat the seawater prior to membranefiltration. The FilterWorx System, which is a gravitymedia filtration system, protects the membranesystem by removing contaminants that can foul themembrane system. The pretreatment system wascustom designed to fit the needs of the Queenslandproject utilizing Leopold filter underdrains with IMScap. At completion the Gold Coast DesalinationProject will provide 125 million litres of drinking waterper day to the residents of Southeast Queensland.

DISSOLVED AIR FLOTATION (DAF)

Operating Principle

Air under pressure is dissolved into water according to Henry’sLaw of Dissolution. Releasing the pressure back to STP via aspecial device creates millions of microbubbles approximately30–100 microns in diameter. The microbubbles attach to flocin the water and float it to the surface for removal.

TABLE ROCK & NORTHSALUDA WATERTREATMENT PLANT, CITYOF GREENVILLE, SOUTHCAROLINA, USAFor over 70 years, theTable Rock and Poinsettsource waters from theBlue Ridge Mountains

in North Carolina were so clear that the water wasunfiltered and only treated with chlorine. When newregulations required all surface water systems to befiltered, the new Table Rock/North Saluda filter plantopened in July 2000. It is designed to handle 284,000m³/day and uses the Clari-DAF system for clarificationand Leopold dual media filters for final filtration. Theavailable land for constructing a treatment plant waslimited, so a small footprint for the clarification stepof the process was desirable. When evaluating theclarification settling system vs. the clarification flotationtechnology, the DAF process proved to reduce theland footprint by 82.7 percent. The DAF system alsoreduces the chemical usage as well as prolongs filterruns and decrease in-plant water usage by 59 percent.All of these savings make production costs 55 percentlower compared to a conventional clarificationprocess plant.

EVITTS CREEK, BEDFORD,PENNSYLVANIA, USAThe Evitts Creek WaterTreatment Plant, locatedon the border ofPennsylvania andMaryland, providesdrinking water to theCity of Cumberland,

Maryland and the surrounding area. Environmentalfactors were causing increased seasonal algae blooms,which created a severe taste and odor conditionand shortened filter run times. To solve the problem,the City of Cumberland contacted ITT. The LeopoldClari-DAF system not only met the main treatmentobjectives, but also enabled a 36 percent increasein plant capacity. New filter and sludge removalsystems further increased operational efficiency.Improvements include:

•80% improvement in clarified water turbidity•400% improvement in filter runs•75% decrease in recycle water needed

The final design and installation was completed inJune 2002, ahead of schedule and under budget.Commenting on the new systems, PlantSuperintendent Rodney Marvin said, “I think I canspeak for everyone when I say we are 100% satisfied.”

CAMBRIDGE,MASSACHUSETTS, USAThe Hobbs BrookReservoir and StoneyBrook Reservoir flow intothe Fresh Pond Reservoirvia the Stoney Brookconduit and provide theraw water source for 24

MGD (91,000 m³/day) water treatment plant for thecity of Cambridge, Massachusetts. In 2001, the plantinstalled a Leopold Clari-DAF dissolved air flotationsystem with two 12 MGD trains with a total of 12concrete flocculators. It includes six concrete DAF basins,two full recycle systems followed by intermediate ozonefor primary disinfection, granular activated carbon gravityfilters that are operated as biological filters, followedby disinfection with sodium hypochlorite (chlorine) andthe conversion to chloramine as a secondary disinfectant.After installation, the plant’s total organic carbon removalconsistently exceeds regulatory guideline requirements.Trihalomethanes and haloacetic acids have also beenreduced to well below the required limits.

FLORENCE,COLORADO, USAColorado South WaterTreatment Plant locatedsouth of Denver handleswater loads of around6 MGD. The plant usesvarious surface watersources that blend into

the resevoir, making the water difficult to treat.Algae growth is an additional problem, especiallyin summertime. To update the plant and improveperformance, the City opted for a dissolved airflotation system. ITT was selected as the provider ofthe equipment for the Leopold Clari-DAF dissolvedair flotation system, the gravity filters, and theplant controls. By December 2005, the project wascompleted – on budget and ahead of schedule. Asa result of the new system, the use of chemicals hasbeen dratically reduced, water quality has significanltyimproved (99% of algea is removed), filter run timeshave increased ninefold and in-plant water use hasbeen reduced by 150,000 gallons per day.

Lovö WaterworksSTOCKHOLM, SWEDEN

Stockholm Vatten,a municipal utilitycompany owned bythe City of Stockholm,produces and suppliesdrinking water of thehighest quality to morethan one million peoplein Stockholm and

neighboring municipalities. To reduce the use ofchloramines, Stockholm Vatten chose ITT’s WedecoUV disinfection system for the Lovö Waterworks.The water source is surface water from lake Mälarennorth-west of Stockholm.

ITT was chosen after an international tender evaluationof full life cycle costs for 20 years. This included costs forequipment, installation and running costs. In addition,technical criteria also weighed in, like experience withsimilar installations, service organization and design ofthe UV control system.

The Lovö waterworks has two production lines. Phase1 is operating with two Wedeco systems, treating aflow of 144,000 m³/day. These systems are certifiedaccording to the German Drinking Water Standardand were the first large scale installations of its kindin Europe in 2001.

Phase 2, six years later, saw two Wedeco reactorsinstalled for treating 168,000 m³/day. Both productionlines have a total installed base of 360 UV lamps fortreating 312,000m³/day.

ITT’s Wedeco disinfection system shows excellentresults, with a 99.9 percent reduction of heterotrophicbacteria and zero coliform and E. Coli per 100 ml. Thelevels of chloramines have been reduced by 50 percent.Formation of trihalomethane is negligible and thelevels of assimilable organic carbon have also beenreduced significantly.

Wedeco UV systems have very high performance UV lampsas the core elements. Electronic control devices amplify theirimpact. Calibrated sensors monitor and log all material factorsfor the disinfection process. For optimum efficiency, specificcomputer based radiation geometries have been developed.

Wedeco ozone systems are usually delivered as completeplants. They can be combined with other processes such asUV disinfection (e.g. multi-barrier disinfection plants), hydrogenperoxide, biological treatment, filtration and chemicalflocculation to achieve optimum results.

STYRUM-OSTWATERWORKS, MÜLHEIM,GERMANYThe Styrum-Ostwaterworks wasconstructed in 1912 inthe city of Mülheim,close to the industrialcentre of the Ruhr. To

handle water shortages, the local groundwater wasrecharged by sand filtered Ruhr River water. In the1960s and 70s, growing demand, drought andperiodic contamination of the river made it necessaryto find a better solution. In 1982, additional treatmentstages were introduced, using the Mülheim Method,which produces high quality drinking water evenwhen the raw water conditions are unfavorable.2003 saw the introduction of ITT’s Wedeco UVdisinfection system, which replaced the use of healthendangering chlorine in the final disinfection. Thismeant significant improvements in the taste and smellof the drinking water. The system is designed for amaximum water throughput of 192,000 m³/day andwas installed while the waterworks was in operation.The performance of the system can be automaticallyadjusted to the disinfection requirements when theflow rate is low. This saves energy as well as money.

WEBER BASIN WATERCONSERVANCY DISTRICT,UTAH, USAWeber Basin WaterConservancy District hasprovided drinking waterto four counties in Utahfor over 50 years. Itswater quality goals are

much more stringent than those of the US State andFederal government. ITT Water & Wastewater builtNorth America’s first large-scale disinfection systemfor “multi-barrier” disinfection of potable water at theWeber Basin Water District in Utah. The contract, usingWedeco UV products, was awarded as part of anupgrade to Weber Basin 3, a 46 MGD (174 000 m³/day)drinking water treatment plant. The process upgradeincludes an ozone oxidation treatment stage followedby disinfection with ultraviolet light. Weber Basin 3is the first large-scale potable water system in NorthAmerica to employ ITT’s advanced low pressure-highintensity ultraviolet lamp technology, used extensivelythroughout Europe for the disinfection of drinking water.

VANCOUVER, CANADAThe Greater VancouverWater District deliverswater to approximatelytwo million people. Newregulations meant thatthe Seymour filtrationplant had to be expandedand upgraded. After

careful evalutation, ITT’s Wedeco UV disinfectionsystem was chosen for the new plant. UV is moreeffective, takes less time to inactivate harmfulorganisms and requires less space compared toother methods. ITT’s UV disinfection system providesthe lowest cost of ownership during the projected20 years equipment lifetime. In addition, Wedecodisinfection units require 3–4 times less energy todeliver the same disinfection capacity into the samewater flow as competing systems. The plant startedoperations in 2008 and is the largest UV disinfectionplant in North America with a total capacity of2.2 million m³/day.

LEPE DRINKING WATERTREATMENT PLANT,HUELVA, SPAINGestión Integral Aguas deHuelva S.A. is one of themost important watersuppliers in Andalucía. Inorder to comply with theEuropean standards for

water quality regarding trihalometanes and pesticides,the company decided to install pre-ozonization andintermediate ozonization, coupled with hydrogenperoxide and granular activated carbon filters in thedrinking water treatment plants of Aljaraque, Tintoand Lepe. ITT Water & Wastewater designed a fullyequipped and automated Wedeco ozone generationstation to supply the ozone gas to the pre-ozonizationand intermediate ozonization steps. The station containstwo units with a maximum capacity of 9,300 g/h ata concentration of 10wt%, from LOX and a watercooling temperature of 20º C. The project was financedby The Public Administration of Andalucía and theunits were commissioned and installed during 2007.

Dubai UAE, MIDDLE EAST

This is one of the world’sten largest seawaterreverse osmosisdesalination plants.Each day it transformssalt water from theArabian Sea into 30million gallons (113,000m³/day) of drinking

water. ITT was issued the contract in 2004 from PALTechnologies, the local engineer, procurer andcontractor that supplied the turnkey package.

ITT designed, manufactured, supplied and installedall products for the plant, taking responsibility for theentire desalination process: from intake pump station,pre-filtration, through to the RO membranes and thedistribution pump station, including instrumentationand controls. Other responsibilities included thefacilities layout plan, civil contractor supervison,commissioning, training and performance guarantees.

“We are responsible for the entire desalinationprocess, from seawater intake to fresh water

distribution” explains Jorg Menningmann, directorof business development for global projects at ITT.“The size of this project and our ability to providea reliable and economical seawater reverse osmosissolution gives us a solid reference in this field. Incombination with our pumping, pre-treatment anddisinfection products and expertise, this capabilityenhances our technical and service offering to ourcustomers regardless of the scope of the project.”

Reverse osmosis technology has existed for decades,but the drawback has always been high energyrequirements. The more salty the water, the moreenergy or pressure it takes to push the water throughthe membranes. To address this challenge, ITT’sinnovative solution includes energy recovery turbinesthat generate their own energy. This has cut externalenergy requirements by 45 percent compared toolder desalination plants.

The project offered several unique challenges, allof which ITT successfully resolved, making reliableand affordable drinking water avalible to the rapidlyexpanding population of this region.

ISLA DE TOAS,VENEZUELAThe residents of ToasIsland, situated inthe middle of LakeMaracaibo, Venezuela,needed a flexible watertreatment system withoperating parameters

that could automatically adjust to drastic changes insalinity (8,000 to 32,000 mg/l) caused by seasonalvariations. Lake Maracaibo had been opened up tothe sea for oil tanker traffic, which meant that oceantidal effects as well as influent rivers had an effecton the water conditions. ITT designed, supplied andinstalled a 400,000 GPD (1,515 m³/day) reverse osmosissystem, specially designed with online monitoringand controls which made process adjustmentssimple while maintaining a steady output.

GIBRALTAR, EUThis 4400 cubic meterper day municipal reverseosmosis system suppliesdrinking water for thecountry of Gibraltar.The system includes allnecessary pre-treatmentand post-treatment to

process Mediterranean seawater to EU drinking waterstandards. The first phase included two 1,000 m³/daytrains. This initial installation performed so well thatITT was given the contract for the expansion to4,400 m³/day that the system was designed for. Theexpansion is accomplished by the simple addition oftwo more packaged 1,200 m³/day trains. The systemhas met product quality and production capacityspecifications since operations commenced. ITT,together with our representative, designed, supplied,installed and commissioned the system. ITT continuesto provide technical support for operations to ensure99+% plant availability.

NEWPORT NEWS WATERTREATMENT PLANT,VIRGINIA, USAThis brackishgroundwater ReverseOsmosis system wasthe first major municipalRO water treatment plantin the commonwealth of

Virginia. Evaluating various ways to meet increasingdemand, brackish water desalting proved to bethe most economic solution compared to otheralternatives. The 5.7 MGD (21,500 m³/day) NewportNews Waterworks RO Plant was primarily designed toprovide safe drinking water, but it was soon realizedthat it provided enhanced water quality as well. Byblending RO permeate with water from a conventionalwater treatment plant, organics were greatly reduced,thereby enhancing compliance with regulationsregarding disinfecting by-products in drinking waterdistribution systems. ITT supplied the RO skids andtechnical support from installation through tostart-up and operator training.

FIVE FORKS, VIRGINIA, USAFacing water supplyshortages due topopulation growth,a coastal Virginiacommunity turned toITT for a turnkey reverseosmosis membranefiltration system to treat

a brackish well water source. Commissioned in 2007,the Five Forks Water Treatment Facility provides 5.0 MGD(18,900 m³/day) of potable water by blending a portionof the well water with RO permeate. Four 1.0 MGDmembrane trains provide the level of treatmentnecessary to meet the high drinking water qualitystandard. The output from the plant is furtherblended with water from other sources to ensure thatthe facility will be able to satisfy the area’s waterneeds until at least 2013. In addition to the RO units,ITT provided the variable frequency drives for the wellpumps, as well as a pilot unit that is used for thetesting of different membranes and of the pre-treatmentand post-treatment chemicals. ITT also supplied theinstrumentation, controls and computer-programmingservices for the plant-wide SCADA system.

TIGHNABRUAICH &TAYNUILT, SCOTLAND, UKTwo nanofiltration (NF)plants, producing158,500 GPD (600 m³/day) and 200,000 GPD(758 m³/day) respectively,were commissionedand built by ITT at the

Tighnabruaich and Taynuilt water treatment sites.These plants are based on a new Package MembranePlant (PMP) concept, which is specially designed tominimize cost and program duration. Constructed ina transportable building at ITT’s production facility,PMP systems are commissioned prior to shipment.The first PMP contract returned a savings of 30 percentin cost and program duration.

COOPER CITY,FLORIDA, USAIn response to thedemand for more andbetter quality water,Cooper City, Floridaupgraded its existing limesoftening water treatmentplant and installed an

advanced water treatment process called Nanofiltration.The principal purpose of the plant was to make use ofhighly colored and hard ground water. ITT performeda pilot study to demonstrate the capability of an NFsystem on Cooper City’s wells.The higly successful resultsof the study tipped the scales in favour of ITT’s solution.A nanofiltration system operates at lower pressures thanreverse osmosis providing lower operating cost. It onlyremoves about 85% of TDS and hardness which is moredesirable in many cases than, say, 98% reduction you getwith RO technology. Yet nanofiltration achieves almost100% color reduction, which is always an advantage.The system has been proven to be the lowest costalternative to meet the City’s requirements for drinkingwater from a previously unusable water well. This plantproduces 3 MGD (11,400 m³/day) of exceptionallyhigh quality drinking water. When blended with theirlime softened water, Cooper City enhances their overallplant output quality by reducing final color contents.

LOWER KUSKOKWINSCHOOL DISTRICT,ALASKA, USACovering a geographicarea equal to the stateof Ohio, the LowerKuskokwin SchoolDistrict is home to alarge number of remote

schools. The district uses eleven ITT water treatmentplants to remove high levels of strongly coloredorganic content from the source water. Ranging insize from 0.6 gpm to 7.5 gpm (3.3 to 41 m³/day), thewater treatment plants are designed for reliability andfor the harsh conditions of the arctic winter. The firstthree systems were installed in containers and fullytested prior to delivery, saving both time and work.Using tubular nanofiltration membranes, the watertreatment plants operate without the need forchemicals other than post-treatment chlorinationand membrane washing. In 2005, one of these systemswon a competition for the best tasting rural waterin the United States. Eight more systems were laterinstalled on groundwaters containing very high levelsof iron, manganese and organics. After pre-treatmentoxidation, the nanofilters remove the organic contentand clarify the water. All systems are connected toeach other by a remote monitoring network.

different processes with high energy input and hasmany ancillary support functions, it is an industry thathas high water usage with varied quality specifications.Baosteel required an industrial grade system thatwould provide flexibility and yet be economical to meetits multiple water requirements. ITT designed, supplied,installed and commissioned a system which produces9.5 million gallons (36,000 m³) of water per day by aprocess of pre-filtration, followed by two pass RO andpartial electro-deionization. The system takes pre-treated surface water through a coagulation filtrationprocess. The water is then processed by a two-pass ROsystem. Water from the first pass is used as generalpurpose plant water, including cooling, as well as feedwater to the second pass RO system. The second passRO permeate water is fed to an electro-deionizationsystem for production of ultra-pure water for boilers.ITT was selected to supply the system because of ourinnovative approach and the resulting economicefficiency of the system. The plant has met all thewater quantity and quality specifications and hasbeen operating successfully for several years.

About 2.6 billion people, or 42 percent ofthe world’s population, lack access to basicsanitation. 18 percent or 1.1 billion peoplelack access to safe drinking water.

Wastewater TreatmentChanging our environment for the better is a step-by-stepjourney. One of the fastest ways forward is to turn wastewaterinto safe water that can be then handed back to nature. Whenwater has served its purpose, it is brought to a treatmentfacility for the breaking down and removal of contaminants.ITT’s advanced aeration systems, sequence batch reactorsand treatment systems form the backbone of such biologicaltreatment systems. Ozone and UV disinfection systems makesure that the water is free from harmful content before itis released and tertiary treatment by media filtration andmembrane systems provide for safe re-use of the treatedwater. The cycle of water contains many steps and ITTprovides equipment for almost all of them.

Cardiff Waste WaterTreatment Works WALES, UK

The plant is designed totreat the waste from avast network of sewersserving the Eastern sideof Cardiff and some ofthe South Wales valleys.This plant is located onreclaimed land close toCardiff docks. To meet

the requirements of the European Urban Waste WaterTreatment Directive and coastal wastewater waterquality legislation, the challenge was to start treatingpreviously untreated sewage from four trunk sewersdischarging directly into the Bristol Channel. TheCardiff project was part of a larger project to installbiological treatment at several coastal locations tomeet the requirements of the Urban Waste WaterTreatment Directive.

This project is also one of the largest SequencingBatch Reactors (SBR) in Europe. SBR technology hasover the past few years become rapidly recognized asone of the most cost effective methods of designinglarge new sewage treatment works that are requiredto meet tight effluent consent standards.

The principle stages of the Cardiff works includeoffsite collection trunk mains with storm storage andpumping facilities, along with a large diameter eight

kilometer collection tunnel transferring the flowsto the main works. This comprises an inlet pumpingstation, inlet works, inter-stage pumping station,16 SBR basins, outfall pumping station, and sludgetreatment plant. The dried sludge from the works issold locally as an agricultural fertilizer.

The Sanitaire ICEAS SBR system offered by ITT wasparticularly competitive as it is a flexible robust systemrequiring minimal land footprint. All flow to the worksis biologically treated in the SBR basins and the finaleffluent is discharged through a four kilometer longsea outfall.

ITT were awarded the contract to design, supply,install and commission the core equipment within theSBR basins, including the fine bubble diffused aerationsystem, 64 stainless steel decanters and the processcontrol software. Opposite basins are hydraulicallylinked to minimize influent pipe costs. There are fourdecanters per SBR basin, linked to a single drive viacarbon fiber line shafts that act as a single decanter.The plant is designed to operate with a maximum oftwo basins out of service.

The plant has fully met the requirements of the waste-water treatment directive since being commissioned.ITT continue to work closely with the client to optimizethe plant operation and minimize energy costs.

WHITEHAVEN WWTW, UKIn collaboration withGalliford Northern, ITTconstructed a SanitaireIntermittent CycleExtended AerationSystem (ICEAS) for NorthWest Water’s first fourbasins ICEAS Sequencing

Batch Reactor (SBR) plant at Whitehaven. The ICEAStechnology is one of the most cost effectivewastewater treatment processes, designed to meettight effluent consent standards. The plant was installedto meet the European Urban Wastewater Directiverequirements and has consistently achieved higherlevels of performance than required to meet thestandards of the directive. Selecting the ICEAS processenabled the new works to fit within the existing site.The construction of the new works did not interruptdischarge flows from the existing works. The detaileddesign, construction and process commissioning wascompleted within 12 months. The reduced civil worksrequired for an ICEAS SBR process and the effectivemanagement by ITT of the installation significantlycontributed to this rapid delivery.

JINSHAN XINJIANGWWTP, CHINAITT provides thewastewater treatmentsolution to the Xinjiangplant in Jinshan, asuburb of Shanghai,using an advanced SBRsystem with effluent UV

disinfection. Funded by The World Bank, the plant hasa capacity of 50,000 m³/day (13.2 MGD), serving apopulation of 250,000. The plant opened in 2006 andis designed to double its capacity in the near future.ITT’s Sanitaire SBR process is the heart of this plant,treating biological wastewater by enhancing thenutrient removal. This is the first facility in Chinaemploying the Sludge Inventory Management System(SIMS) that gives plant operators a completelyautomated sludge wasting routine that enables theplant to optimize nutrient removal as well asoperational costs. This is also the first Chinese facilitywith a Wedeco UV disinfection system that destroysthe pathogens in the water using ultraviolet light,making the final effluent harmless to theenvironment. Other ITT products included in thisfacility are Flygt Pumps and Mixers and RoyceInstrumentation – a classic ITT product portfolioin the municipal wastewater treatment segment.

TULLAHOMA CITY,TENNESSEE, USAOne of ITT’s first SanitaireICEAS plants wasprovided for Tullahoma’smunicipal wastewatertreatment facility, whichcontinues to producehigh quality effluent and

has never been out of compliance in over 20 yearsof service. In 1994, the City upgraded the plant toaccommodate flows up to 30 MGD (113,600 m³/day)and installed ITT‘s fine bubble membrane disc diffusersto reduce energy costs and maintenance expenses.The City selected the ICEAS process, over an OxidationDitch and In-Channel Clarifiers, as the most economicoption. The original estimate of the project wasten million dollars but the final cost only amountedto 5.1 million. The ICEAS facility has proven to beextremely cost-effective and consistently produceshigh quality effluent in spite of a highly variableorganic load due to discharges from two localtanneries and an electroplating plant.

MARAGHEH, IRANITT was selected todesign and supply acomplete SanitaireSequencing BatchReactor (SBR) ICEASplant at the MaraghehSewage TreatmentWorks in East Azerbaijan,

Iran. This system is the second stage of a three-phasedevelopment. The original plant used a conventionalActivated Sludge Process whereas the new extensionuses the ICEAS SBR process installed into only 2 basins.The incoming flow is directed to the SBR’s flow via acommon distribution chamber. The flow is routedfrom the distribution chamber to the pre-react chamberof each SBR. At the opposite end of each basin, theeffluent is removed through decanters dischargingvia an internal collector pipe. Aeration is provided viafine bubble membrane diffusers on the floor of theSBR basins. Reliability and simplicity of operation arekey attributes of this process. The plant is designedto operate both as a true SBR and in ICEAS mode.

Sulaibiya ProjectTHE WORLD’S LARGEST WATER REUSE INSTALLATION, KUWAIT

The Arabian Gulf countryof Kuwait is at the heartof the Middle East, aregion that representsalmost 5 percent of theworld’s population butless than 1 percent of itswater resources. About75% of Kuwait’s potable

water must be distilled or imported. Looking toconserve its limited water supply, the small countryhas built the world’s largest water reclamation andreuse center.

Two major problems led to this decision. First, theexisting wastewater treatment plant at nearby Ardiyahad reached capacity. Secondly, the country’s brackishwater resources are now no longer sufficient to meetthe growing demand for non-potable use. The Sulaibiyawastewater project is designed to resolve both of theseissues. Prior to treatment at Sulaibiya, more than tenpipelines feed wastewater for pre-treatment to theArdiya plant from Kuwait City and the surroundingarea. A 25 kilometers long main pipeline conveys thepre-treated flow to the new Sulaibiya plant, where itis treated to potable water standards.

The plant comprises three elements – biologicalnutrient removal, RO / UF membranes and sludgetreatment. A new 1 kilometer pipeline transportsthe finished effluent to the nearby brackish watergathering center prior to use, while the membranesystem brine overflow is returned to the sea viaanother pipeline to the existing Ardiya outflowchannel.

ITT was chosen to design, build and commissionthe aeration, mixing and pumping system at theSulaibiya plant. ITT was also contracted for the designand supply of aeration equipment for oxidationditches and digesters for the Sulaibiya project, leadingto an ultimate capacity for the works of 158.4 MGD(600,000 m³/day). All product installation has beendesigned with consideration to the intense demandsfrom Kuwait’s climate.

The water produced from this plant is used to irrigatelandscape areas along highways, main roads andpublic gardens in large parts of Kuwait City. Verticalmultistage pumps from ITT are driving the first phaseof this irrigation scheme, and will also be used forthe second phase.

Sanitaire fine-bubble diffused aeration is the most efficient inwastewater applications, i.e. the amount of oxygen transferredto water per input energy is among the highest in the market.The Sanitaire membranes maintain a high efficiency for a largenumber of years.

Flygt low speed mixers effectively move and mix large volumeswhile incurring extremely low energy costs. They are the obviouschoice in oxidation ditches and large tanks in biological treatment.Direct-drive stainless steel compact mixers are easy to install inboth new and existing tanks.

Flygt pumps work efficiently in wastewater and sludge with upto 10% dry solid content. Progressive cavity pumps are availablefor use in dewatered sludge. Propeller pumps deliver high flowrates at low or ultra-low head with N-technology to ensureuninterrupted operation at sustained efficiency.

BECKTON STW, UKLocated in Newnam onthe north bank of theriver Thames, the BecktonSTW was first connectedto the London Sewernetwork in 1850. Today,it serves a population of3.5 million people and

is one of the largest treatment works in the UK. Theframework contract awarded to ITT has provided forthe supply and installation of more than 195,000Sanitaire fine bubble membrane disc diffusers and1,000 km of associated PVC pipe-work over a five-year period and represents an investment in aerationequipment by Thames Water of more than £ five million.ITT acted as the Principle Contractor under CDMregulations during the installation of much of the work.The replacement of the aeration system has enabledthe works to better meet the biological treatmentrequirements and reduce the energy costs for the plant.

VIENNA, AUSTRIAIncreasing environmentalregulations and sewagevolumes required themodernization of themain sewage plant inVienna. The plant startedoperations in 1980 andpurifies wastewater from

a population of four million people. Along with watersafety, energy efficiency was a high priority for the localauthorities. After test evaluation, the ITT solutionproved to be the most efficient. ITT delivered a total of120 Flygt slow-rotating agitators and 48,435 Sanitairedisc fine bubble aerators for the new aeration tanks. Inthe 1980s, a degree of purification of 85 percent wassufficient. After completing the modernization in 2005,the plant has achieved a constant 95 percent thanks tothe aeration system supplied by ITT that is used in thebiological treatment process. The plant has proved tobe stable, reliable and extremely energy efficient. So farthere have been no malfunctions, failures or repairs thatmight have disturbed the internal biology of the plantor caused shutdowns. No wonder that the operatorsare completely satisfied with their choice of ITT.

WARREN CITY,MICHIGAN, USAITT installed over 8,000ceramic Sanitaire discdiffusers with an in-situgas cleaning system forthe City of Warren’swater treatment facility.ITT also provided a

three-year diffuser cleaning contract through theirlocal representative. The City’s decision was based onthe anticipated energy savings expected from ITT’sSanitaire high efficiency diffusers over their old system,which was both inefficient and trouble-prone.

ManukauNEW ZEALAND

The upgrade of a30-year old sewagetreatment plant,involving the integrationof the latest UVdisinfection technology,was carried out as partof a 244 millionmodernization project,

coordinated by Manukau Wastewater Services.When completed in 2001, it was the world’s largestwastewater disinfection system.

The screening system was revamped, nine newcombined reactor-clarifier tanks have been installedand a new tertiary wastewater treatment system isnow in place, consisting of sand filtration reinforcedby UV disinfection.

The Wedeco UV disinfection system consists of 12 open,17m-long wastewater channels, which are integratedinto a purpose-built structure. Each channel contains3 banks of UV lamps with a total of nearly 8,000

high-performance UV lamps disinfecting 1.3 million m³of wastewater (or 365 million gallons) per day.

The purpose of this ambitious large-scale project isto protect the environment in the coastal waters ofManukau/Auckland and safeguard the health ofbathers. According to the New Zealand authorities,the upgraded system is bringing about a considerableimprovement in water quality. The local populationwill soon be able to swim and gather shellfish again inan area that has been closed to the public for 40 yearsdue to the extreme pollution caused by the dischargeof wastewater from the city of Auckland.

The decision to entrust this major order to ITT cameafter extensive testing of a number of competingsystems by WaterCare Services Ltd. Chemical-freedisinfection is gaining in importance not only inNew Zealand but also in many other parts of theworld, where this environmentally-friendly methodis now regarded as state-of-the-art technology, andis increasingly referred to in legislation governingwastewater treatment.

Wedeco UV systems Type TAK provides a proven andenvironmentally friendly method of disinfecting wastewater.When exposed to UV-C light, microorganisms are inactivatedwithin seconds through a physical reaction with the organism’sDNA. In contrast to chemical disinfection, UV produces noharmful by-products. It also eliminates the risk to operatorsassociated with handling dangerous chemicals. UV disinfectionversus chemical methods gives increased disinfectioneffectiveness (especially against viruses) and is space-savingdue to shorter reaction times.

UMM AL-HYMAN SEWAGETREATMENT PLANT,KUWAITThis Wedeco UV systemfrom ITT consists of 288low-pressure high outputlamps arranged in fourbanks in two concretechannels to purify

62,000 m³ of water per day. The water level in each ofthe two channels is maintained constantly with the helpof a downward opening penstock. A purely mechanicalwiping system prevents organic and inorganic depositsfrom accumulating on the lamp protective quartz tubesto ensure that the UV light actually reaches the water.The lamps are powered by electronic smart ballastsand monitored by a PLC, which enable adjustmentsto the UV lamp output for the water quality and flowrate. This reliable disinfection control uses UV intensitysensors that feature excellent UV selectivity, operationalstability and a long operating life.

MUNICH, GERMANYThe bacteriologicalcontamination of theriver Isar had longprevented its use for safebathing. To improvewater quality, all sewagetreatment plantsdischarging into the Isar

Karl XII pump stationSTOCKHOLM, SWEDEN

Stockholm is sometimesdescribed as the Veniceof the North – a fittingtitle for Sweden’sbeautiful capital city.But unlike Venice,Stockholm’s reputationfor clean water is world-renowned. Water that is

both clean enough to swim in and to fish in. By 1994the Karl XII station’s pipes and three De Laval cast ironpumps were nearly 60 years old. A breakdown at thestation would constitute a very serious environmentalhazard. The prospect of untreated sewage flowingout into the waters of central Stockholm would bedisastrous for a city that had staked its reputation onthe purity of its water.

Having considered a number of alternatives for therenovation of the station the Stockholm Water

Company decided to replace the old pumps with fournew Flygt CZ 3501 pumps, thus creating two stationsin one. Originally fitted with one pressure pipe, a newpipe was connected at the station to increase safetyand the old pipe was relined.

The four Flygt pumps, designed for optimumfunctionality, were grouped in such a way that eachpair had its own pressure pipe connection. This, ineffect, created two separate systems capable ofoperating independently or in several combinations.The most unusual aspect about this solution alsohappens to be the feature the client found mostattractive. This is that, unlike most dry installedsubmersible pumps of this size, the Flygt pumpscould be installed horizontally instead of vertically– a crucial point in view of the fact that the stationhas a very low ceiling. The pumps are assembled ina “gun cradle” and can simply be dismantled and“rolled out” for service and inspection.

NEW ORLEANS,LOUISIANA, USAITT’s Flygt pumps andsystems helped keep theNew Orleans area free offloodwater during theonslaught of HurricaneGustav in the fall of2008. Positioned at 25

different pumping stations in Jefferson, St. Charles,St. Bernard and New Orleans parishes, Flygt pumpshave a total pumping capacity of 20 million gallons ofwater per minute. The pumps serve as additionalcapacity to the city’s existing flood water infrastructureto manage water levels in the event of natural disasterssuch as Gustav. “We expected our pumps to keep NewOrleans dry as powerful Gustav bore down,” said JimPeterson, managing director of ITT’s large pumpsdivision in its Water & Wastewater business. “ITTmarshaled its resources in the region to ensure we hadthe right people in place to provide emergency serviceas the storm approached. In the end, the pumps andpeople performed exactly as expected.” ITT’s Flygtpumps are part of a sophisticated system that servesthe east bank of New Orleans by draining stormrun-out to prevent flooding. When the city lostelectricity during the storm, diesel fuel and standbygenerators powered the pumps to keep pace asthe storm surge moved through the canals.

CALUMET TARP,CHICAGO, USAThis project includedreplacing some split casepumps that were old andfalling apart. ITT providedfour new Flygt pumpsand connected them tothe existing 6,000 hp

electric motors. Each of the pumps is rated at 50,000GPM at 375 ft (3.15 m³/s at 114 m). Efficiency wasvery important and ITT guaranteed 89percent rates.The pumps are located approximately 250–300 feet(75–90 m) below ground level and had to be loweredin three pieces through a hole in the roof of the tunnelbefore installation. They are used to pump sewagefrom the deep tunnel and up into the plant forprocessing. Greater Chicago has installed several ITTpumps. Most of them are split case pumps and areused in connection with sewage treatment. It is a fairlyunusual service for a split case pump in US.

BRUSSELS, BELGIUMThe sewers of the Belgiancapital, Brussels are stillcleaned by hand-movedcarts from 1870.However, to solve thecity’s severe floodingproblems, new solutionswere necessary. In order

to stop wastewater from flowing back from thecollectors and flooding cellars, ITT installed a pumpstation with Flygt pumps that automatically pumpexcess water back into the river till water levels startto fall. A new monitoring and control system was alsoinstalled by ITT, linking the new pump station to otherexisting pump stations and retention basins. Thecomputerized network keeps track of the volume ofwater pumped and checks the need for maintenancearound the clock. The system generates daily reportsbased on data collected, and alerts the operators viatheir mobile phones when there seems to be aproblem. Recent high tides and heavy rainfalls havenot caused any of the problems Brussels used to suffer.

YULANGYZ CANAL,TURKMENISTANIn 1996, due to a lack ofmaintenance after thefall of the Soviet Union,the system of irrigationchannels in EasternTurkmenistan had beendeteriorating. Over a

four-year long period, ITT reconstructed the mechanicalas well as the electrical supply systems in order torestore and improve irrigation in the area. The projectincluded 61 large low lift submersible Flygt pumpsin six pumping stations with all electronic controlequipment plus a system for automating theoperation of the pumps. The project was successfullycompleted in spite of the scarcity of local suppliesand inadequate infrastructure.

Water demand is doubling every 20 years,more than twice the rate of population growth.

About 70 percent of all available freshwateris used for irrigation in agriculture.
