Abstract :
In this study, a new composite coagulant, which was prepared by ployferric chloride (PFQ and polydimethyldiallylammonium chloride (PDMDAAC), was adopted to treat surface water. The effect of coagulant dosage and pH of dye water on the removal efficiency was examined. The results showed that PFC-PDMDAAC is shown to be more effective in removal efficiency than that of PFC and PDMDAAC. And the removal efficiency of PFC-PDMDAAC was found to be related to the weight percentage of PDMDAAC (Wp) and intrinsic viscosity (η) of PDMDAAC. When Wp is 7% and η is 1.21 dl/g, the removal efficiency is the highest in our study.
