Abstract

Coagulation efficiencies of some organic compounds by aluminum based coagulants including alum, PAC, PACS were studied. The coagulation efficiency was highest at the neutral pH. It was decreased with an order of PACS, PAC, and alum at the neutral pH. The organic compounds of high molecular weights showed good coagulation efficiencies with all coagulants, while the small molecules were not coagulated. Organic compounds having more than two adjacent functional groups of OH and COOH showed coagulation efficiencies of 10~80%.
