- Abstract
The study investigated the effect of coagulant dosage, flocculation time, and precipitation time on the turbidity removal rate of Oxidized Poly-silicic-ferric (OPSF) coagulant compared with the polyferric aluminum (PFA) coagulant. The effect of OPSF on coagulation and filtration under short-time coagulation conditions was also studied. Experiments showed that when the optimum dosage was 6 mg/L, the flocculation time had a significant influence on the turbidity removal rate of OPSF. With the increase of precipitation time, the turbidity removal effect of OPSF was relatively stable, which was about 94%. The OPSF short-term coagulation and ordinary coagulation have the same effect on the turbidity removal effect, but PFA was different. And OPSF “short-time coagulation and filtration” was better than PFA “ordinary coagulation and filtration”.
