    Turbidity reduction by coagulation-flocculation in drinking water reduces microbes and organic matter, increasing effectiveness of downstream treatment. Chitosan is a promising household water coagulant, but needs parameters for use. This study tested the effects of chitosan dose, molecular weight (MW), degree of deacetylation (DD), and functional ...

    The amount of sludge produced during clarification can be reduced by 50-90%. The approximate dry weight of solids removed per pound of dry alum and ferric sulfate are approximately 0.25 and 0.5 lb, respectively. The resulting sludge contains less chemically bound water and can be more easily dewatered. Polymeric coagulants do not affect pH.
