The City of Scottsdale's Chaparral Water Treatment Plant recently began operation
treating Salt River Project water using an innovative integrated process consisting of
coagulation for arsenic removal, direct filtration through submerged ultrafiltration
membranes, and granular activated carbon (GAC) contactors for total organic carbon (TOC) and taste and odor causing compound
removal. Ancillary processes include plate settlers for wash water recovery and
centrifuges for solids removal. The unique process for this new 30 mgd facility was
developed through six months of pilot-scale operations which competitively compared
four membrane systems as well as ozone and two different types of GAC. Membrane
processes were preferred due to the very small site and the highly variable water quality
delivered to the plant. The entire facility, including the 5.5 mg buried reservoir, sits on
only 11 acres and is constructed to minimize neighborhood impact.
