Abstract

Polyferric silicate sulphate (PFSiS), a hybrid coagulant was amalgamated by co-polymerization technique using Ferric salt and Polysilicic acid at different OH/Fe ratio and Fe/Si molar ratios. The main intention of this paper was to optimize the factors for the turbidity removal in coagulation-flocculation process in water treatment using Box Behnken method. Effectiveness of important process parameters Fe/Si molar ratio, OH/Fe molar ratio, pH and dosage were enumerated, optimized and designed effectively. Valid quadratic polynomial models were obtained. Hence, PFSiS has proven the capability for the turbidity removal in low turbid water.
