Title: Characteristics and flocculation effect of composite flocculant polyaluminium chloride-polyacrylamide
Abstract:Inorganic and organic composite polymer flocculant polyaluminium chloride-polyacrylamide(PAC-PAM) was prepared in this research.Optimum turbidity removal,below 4.0NTU,was achieved with 8mg·L-1 dosage(...Inorganic and organic composite polymer flocculant polyaluminium chloride-polyacrylamide(PAC-PAM) was prepared in this research.Optimum turbidity removal,below 4.0NTU,was achieved with 8mg·L-1 dosage(calculated as Al3+) under raw pH.In this paper studies on flocculating mechanism of composite flocculant were also conducted through comparisons of zeta potential,morphology before and after treatment,the particle size distribution of different flocculants.The results show that hydrolysate of composite flocculant has more positive charges and a structure of branch long chain which enhanced the effect of electrical neutralization and adsorption bridging.Read More
