This powerpoint presentation presents a project to: conduct piloting and related investigations in support of a regional desalination facility; up to 71 mgd finished water capacity for Bay Area water agencies; and, piloting will be conducted from July 2008 to January 2009. Pilot test objectives were to: determine preferred membrane treatment; test technologies to maximize the plant efficiency; test pretreatment residuals; identify and test brine toxicities and potential impacts of brine discharge; test product water quality; and, address potential for adverse environmental effects to aquatic organisms due to source water intake. The experimental plan included the following: coagulation assessment, including jar testing and dose confirmation runs during startup; pretreatment flux and recovery testing, including 1000 hours each trial and test 3 fluxes, but target recovery > 94%; RO flux and recovery testing, including 1000 hours each trial and test baseline and challenge flux at 2 seasonal conditions; cleaning efficiencies, including determining flux restoration at each CIP. Includes tables, figures.
