Abstract

In order to enhance the coagulation pretreatment of a reclaimed water plant, an experiment was employed by means of the Polymerization Aluminum Chloride (PAC), the Polyferric Sulfate (PFS) and the Ferric Trichloride (FeCl₃). The performances of Powder Active Carbon (PAC) and Pre-coagulation Chlorine Addition using as coagulant aids were also discussed. The results showed, turbidity removal could reach 87.5% by using PACl as coagulant, optimum dosage should be 12~ 16mg/L; Compound of PSF and PACl had better performance than Compound of FeCl₃ and PACl; PAC and Pre-coagulation Chlorine Addition could enhance the effect of coagulation process.
