Coagulation performance and mechanism of polyaluminum ferric

Polyaluminum ferric chloride (PAFC) is an efficient inorganic polymeric coagulant , . Many studies [3] , [4] , [5] have demonstrated that inorganic polymeric coagulants were more effective than conventional inorganic coagulating salts in coagulation due to their resistances to the influence of wastewater initial pH.

Abstract. Abstract. This study investigated three common coagulants (alum sulfate (alum), polyaluminum chloride (PAC), and ferric chloride (FeCl 3 )) to determine the best coagulant and optimal dosages in terms of TOC, DOC, turbidity, and conductivity in multiple types of blended water. In the blended surface water and ground water experiment, PAC displayed the best performance in terms of coagulation at a dosage of 20 mg/L.
