The City of Scottsdale's Chaparral Water Treatment Plant recently began operationtreating Salt River Project water using an innovative integrated process consisting ofcoagulation for arsenic removal, direct filtration through submerged ultrafiltrationmembranes, and granular activated carbon (GAC) contactors for total organic carbon (TOC) and taste and odor causing compoundremoval. Ancillary processes include plate settlers for wash water recovery andcentrifuges for solids removal. The unique process for this new 30 mgd facility wasdeveloped through six months of pilot-scale operations which competitively comparedfour membrane systems as well as ozone and two different types of GAC. Membraneprocesses were preferred due to the very small site and the highly variable water qualitydelivered to the plant. The entire facility, including the 5.5 mg buried reservoir, sits ononly 11 acres and is constructed to minimize neighborhood impact.
