Abstract: In this present study, strongly cationic coagulants were prepared by modifying chitosan with 3-chloro-2-hydroxypropyl trimethyl ammonium (CTA). The coagulation properties of this cationic chitosan (chitosan-CTA) were systematically examined in laboratory and pilot scale studies. At the laboratory scale, the effects of coagulant dosage, temperature, initial turbidity of untreated water, pH, and salinity were investigated by a jar test using kaolin suspension as synthetic water. Compared with several conventional coagulants, chitosan-CTA showed a lower dosage requirement of approximately
