This powerpoint presentation begins by providing a brief overview of the Long Beach Water Department's (LBWD's) Seawater Desalination Program. Concerns with seawater quality are presented, along with bench-scale disinfection byproduct (DBP) testing and corrosion testing, LBWD pipe materials, corrosion indices, marble test, pipe section test, and water conditioning. Corrosion testing results include the following: for Indices, the aggressiveness index, RSI, and CCPP correlated well with LSI, and indicated that up to 50% DS blend should be acceptable; for bench-scale tests, marble tests correlated well with LSI, and pipe section tests provides better indication of behavior of water with specific pipes; and, for pipe material, seal-coating provides better protection against corrosion than no seal coat. Includes tables, figures.
