MEMBRANE TECHNOLOGY - Black & Veatch

MEMBRANETECHNOLOGYINNOVATIVE, GLOBAL TREATMENT SOLUTIONSFOR WATER AND WASTEWATER

COVERING THE WATERFRONTWith a track record of more than 50 membrane facilitydesigns worldwide, Black & Veatch is a global leader inmembrane filtration for drinking water, reclamation/reuse andwastewater treatment. The company has designed a combinedmembrane capacity exceeding 600 million gallons per day(mgd), 2270 million liters per day (Ml/d), on five continents.MEMBRANE FILTRATIONBlack & Veatch has extensive experience in evaluating,designing and constructing membrane facilities.

RO provides a side benefit of softening the water.A pilot program verified the design.With an agricultural theme, the building blends wellwith the surrounding 40-acre park-like setting and biketrail. A 55-foot silo disguises a forced draft decarbonator,which adjusts the pH of the water for corrosion controlwhile cost-effectively allowing gravity flow to the finishedwater storage. The facility has earned several awards,including Project of the Year from American Public WorksAssociation’s Chicago Chapter.CHAPARRAL WATER TREATMENT PLANTScottsdale, ArizonanAward-winning facilityincorporates technologywith unique architecturalthemenBlends into adjacentneighborhood and parknSix-month pilot studycompared treatmentalternatives and costsnFerric coagulation andsubmerged UF for filtration and arsenic removalA key challenge—in addition to water treatment—wasblending the facility into the neighboring park andconstrained footprint. The project team achieved this witha cost evaluation, pilot and design that included selectingequipment with the lowest life cycle cost. The pilotcompared four types of membranes and two grades ofGAC operated with and without preozonation.The resulting 30-mgd Chaparral WTP treats surfacewater with ferric coagulation, submerged UF membranes,granular activated carbon and hypochlorite generatedon-site for arsenic removal, filtration, taste and odor, anddisinfection byproduct control.The plant has received many awards, including the GrandAward (Arizona’s American Consulting Engineers), Art inPublic Places Award (Valley Forward Association), WaterProject of the Year (Arizona Water Pollution Control Association), and Judges Special Award of Excellence (PCBC,formerly known as the Pacific Coast Builders Conference).BL ACK & VEATCH 3
