| Abstract: | After the preparing chitosan in laboratory scale, the production of chitosan used for flocculant in medium scale was carried out . The optimum processes for producing chitosan in the three steps of reaction including removal calcium,removal protein and deacetylation were obtained. Comparing with the other methods for producing chitosan, the cost of this method cut down 22%, the production period shortened 66%, and the main properties were closed to or exceeded the commercial chitosan products. |
