This slide presentation outlines a study with the objectives of conducting long term (18 months) testing withceramic membranes for performance and the effect of pretreatment.Topics outlined include: advantages of ceramic membranes; concerns of ceramic membranes; structure of ceramic membranes; filtration and backwashing mechanisms; Japanese installations; important research steps; testing objectives; chemical cleaning; pilot testing; Effect of pH Between Chemical Cleans; and, cost comparison. Concluding remarks include:large amount of Acid Hydrophilic NOM, nextphase to use MIEX as pretreatment;increasing pH from 5.5 to 7 improved formation of cakeand allowed better recovery;lower pH increased fouling reduced economicoperation; and,flux can be increased to 150 lmh by carefullyoptimizing coagulation. Includes tables, figures.
