Floc’s Formation and Settlement of Organic Poly-Silicic-Ferric Coagulant

Abstract:

Article Preview

A new coagulant, organic poly-silicic-ferric (OPSF) was prepared by adding dimethyldiallylammonium chloride (DMDAAC) in poly-silicic-ferric (PSF) coagulant. The process of floc’s formation and settlement during the coagulation process was investigated, in comparison with that of PSF. The results show that OPSF gave higher speed of floc formation and precipitate than PSF, and large flocs of OPSF were formed faster than PSF. The floc density of OPSF was greater than that of PSF, thus leading to much less amount of OPSF flocs in the supernatant than that of PSF after basically full settlement.
