Scottsdale adsorbs total organic carbon problem
This report discusses a case study where the City of Scottsdale, Arizona, will be impacted by the proposed Stage 2 Disinfectants/Disinfection Byproducts Rule (D/DBPR) in its treatment of Salt River Project (SRP) water. The SRP water is a combination of moderate total organic carbon (TOC) concentrations, high water temperature, and free chlorine which creates high levels of chlorinated disinfection byproducts, especially trihalomethanes. Because chilling the water would be very costly and replacing free chlorine as the distribution system residual disinfectant would present other problems, Scottsdale decided that removal of TOC was the best way to meet the requirements of the Stage 2 D/DBPR. This report discusses the selection of microfiltration/ultrafiltration (MF/UF) followed by granular activated carbon (GAC) as the process configuration at its new Chaparral Water Treatment Plant. To maximize the effectiveness of GAC, the project team also evaluated such factors as type of GAC, contact time, configuration, and replacement frequency.
