Abstract:With FeCl3 used as coagulating agent, and CTS as coagulant aid, the influence of chitosan coagulation aid on floc form and strength was studied. Under the FeCl3 dosage was 29mg/L, CTS dosage was 0.1mg/L, the effect of chitosan coagulation aid on floc form and strength was obvious. The fratal dimension and SF increased from 1.1855 and 50~60 when FeCl3 was dosed only, to 1.3028 and 60~70 when chitosan was used as coagulation aid. Chitosan coagulation aid had marked influences on floc form and floc strength, chitosan coagulation aid helped to make the floc dense and easy settlement, to make the floc strength and not easily broken. In addition, the removal efficiency of TOC, chroma, UV254 and turbidity were improved obviously.
