Abstract: This study involves on valorization of Algerian marine waste, shrimp shells, in treatment of urban sludge (organic) by coagulation-flocculation / filtration. So, transformation of chitin into chitosan has been realized in laboratory in order to make a bioflocculant. Therefore, chitosan prepared had been tested for conditioning of urban sludge from Tizi-Ouzou wastewater treatment plant. The results indicate that chitosan shows a biocoagulation-bioflocculation behavior which is similar to standard chitosan.
