Bench-Scale Evaluation of Nanofiltration Concentrate Disposal for an Inland Treatment Facility

摘要

To meet the requirements of the Stage 2 Disinfectant and Disinfection By-Products Rule (D&DBPR), removal of disinfection by-product (DBP) precursor materials must be improved at the water treatment facilities owned and operated by the Cobb County-Marietta Water Authority (CCMWA). CDM has been working with the Authority since 2002, investigating alternative treatment technologies to reduce DBP precursors at the Hugh A. Wyckoff Water Treatment Plant (WTP) (Comstock, 2003; Isabel, 2004; Isabel, 2006). The study was conducted at this plant since it is the facility that provides water to CCMWA’s most remote customers and will be most influenced by the new DBP regulations.
