Abstract
According to the coagulation tests for PACs with various basicities, the PACB with lower basicity showed higher coagulation efficiencies of organics and phosphorus than the PAC with higher basicity. The PACB contained higher amount of monomeric Al (III) hydrolytic species comparing with PAC. In case of the coagulation for the sewage treated water, the coagulation efficiency by the charge neutralization and sweep floc formation was higher with PACB than with PAC. Accordingly, when $Al_2O_3$ concentration was similar in the coagulant, PACB showed higher removal efficiencies of turbidity, $COD_{Mn}$, TP, and $PO_4$-P comparing with PAC, especially in the lower range of coagulant dose.
