AWWA ACE68649

This powerpoint presentation presents a project to:conduct piloting and related investigations in supportof a regional desalination facility; up to 71 mgd finished water capacity for Bay Areawater agencies; and,piloting will be conducted from July 2008 to January2009. 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 impactsof brine discharge;test product water quality; and,address potential for adverse environmental effects toaquatic organisms due to source water intake. The experimental plan included the following: coagulation assessment, including jar testing anddose confirmation runs during startup;pretreatment flux and recovery testing, including1000 hours each trial and test 3 fluxes, but target recovery > 94%;RO flux and recovery testing, including1000 hours each trial andtest baseline and challenge flux at 2 seasonal conditions; cleaning efficiencies, includingdetermining flux restoration at each CIP. Includes tables, figures.
