Full Description

The objective of this slide presentation was to evaluate whether existing models for estimating Total Trihalomethane (TTHM) formation potential could be successfully applied to California State Project Water (SPW) pre-treated with a magnetic ion exchange (MIEX) resin, followed by conventional coagulation, flocculation, sedimentation, filtration and free chlorine disinfection. The methodology included: evaluation of five literature published models;data sets from MIEX jar tests and pilot trials;MIEX and MIEX plus coagulation treatment;three SPW sites; and,formation potentials under site specific Simulated Distribution System (SDS)conditions. Models included:US Environmental Protection Agency (USEPA) Water Treatment Plant WTP Model(CDWO (2001); verified Solarik et al (2000));USEPA-MPI (original)(Harrington et al (1992));(DWR (original and recalibrated)(Hutton and Chung (1992,1993)); and,Palmdale Water District (PWD)(developed by Carollo Engineers for AWWARF Study). Sites included:Metropolitan Water District (MWD);Covina Irrigating Company (CIC); and,Palmdale Water District (PWD). Includes 3 references, figures.
