Abstract: Chitosan is a useful product from shrimp shell wastes. It has significant role in many areas such as medicine, agriculture, industry, biotechnology. . . To develop application of Chitosan in wastewater treatment, research has been conducted on the biological flocculation ability of Chitosan to treat white effluent from paper industry to recover pulp lost. First, Chitosan was extracted from shrimp shell and then Jar test model was built to find optimal conditions for flocculation in the treatment process. The experimental results showed that Chitosan optimal dosage is 100 mg for treatment of each litre of the paper white effluent at normal temperature, resulting in total suspended solid (TSS) reduced by 95.43%and true colour units reduces by 91.60%. Thus, application of Chitosan derived from seafood processing industry waste will contribute to improving the economic resources, reducing solid waste generation and wastewater pollution, helping protect the environment.
