In this study, a new composite flocculent was prepared from polyferric chloride (PFC) and polydimethyldiallylammonium chloride (PDMDAAC). The Fe( ) species and zeta potential of the composite flocculent (PFC-PDMDAAC) and PFC were measured by a timed complexation spectroscopy method and the malvern Zetasizer 3000, respectively. The flocculation efficiency of PFC-PDMDAAC for treating actual surface water or wastewater samples was compared with that of PFC. The results showed that when PDMDAAC fraction (Wp) is 7.0%, PFC-PDMDAAC contains the smallest content of Fec and has the highest zeta potential. PFC-PDMDAAC is more effective than PFC and PDMDAAC in water and wastewater treatment. Therefore, the use of PFC-PDMDAAC is both technically and economically feasible in water and wastewater treatment.
