The Characteristics of Chitosan Applied in Drinking Water Treatment
Chitosan is a kind of natural, non-toxic and harmless substance. After its amino-group protonizing, it can form a cationic polymer which has excellent coagulation/flocculation properties. The application of chitosan in potable water treatment for the removal of particulates and dissolved organics has been studied extensively in the last decade. In order to further understand the specific property of chitosan applied in drinking water treatment, this paper introduces the effect of molecule weight and deacetylation of chitosan on coagulation/flocculation and coagulation/flocculation mechanism in drinking water treatment, gives an overview of chitosan characteristics of removal of suspend solids, organics and bacteria in water, particularly, describes the relationship between the removal efficiency of above impurities by chitosan and pH, dosage of chitosan.
