AWWA ACE68673

This powerpoint presentation begins by presenting background information on the Lytle Creek Water Filtration FacilityPilot Study, and the sources of water for Southern California. Pilot test objectives wereto determine:what combination of the pre- and post-treatmentwill meet TOC removal goals most cost effectively;simulated distribution system (SDS) disinfectionbyproduct (DBP) levels for each treatment train;appropriate ACH dosage for inline coagulation;effect of MIEX pretreatment, floc sed, and inlinedosing of ACH on MF performance; and,collect MF, GAC and MIEX operating datafor final design. Methodology included:run each train at least 3 weeks;filtrate flow at 22.5 gpm (37 gfd flux);CIP performed between test runs; and,SDS DBP samples. Pilot test conclusions indicate that:condition #4 (MIEX + MF + GAC) haslowest O&M cost;MF with only post-GAC adsorption hasthe highest O&M cost;MF design is similar for all four treatmentoptions; and,0.1% HCl maintenance washes arerequired for inline coagulation. Includes figures.
