Abstract
The flocculation of turbid water using polyferric chloride-polydimethyldiallylammonium chloride (PFC-PDMDAAC) has been studied. Effect of preparation parameters basicity ratio (B ratio) of PFC and PDMDAAC/PFC ratio and operating parameters pH and dosage were investigated. PFC-PDMDAAC displayed maximum turbidity removal of 94.8% at 4.0mg/L when B=0.5 and PDMDAAC/PFC ratio = 7%. The best turbidity removal efficiencies by PFC-PDMDAAC were 84.7% at pH 7.5. These results reveal that PFC-PDMDAAC is efficient for flocculation of turbid water.
