Chitosan was coated into polyamide membranes by in situ reaction of amine and hydroxyl groups ofchitosan and un-reacted of acylchloride of polyamide active layer. Effect of chitosan concentration andcoagulation time on the membrane chemical structure, morphology, separation performances and antifoulingproperties were characterized by FT-IR, SEM, AFM, cross-flow membrane module device andcetyltrimethylammonium bromide experiment. Water flux of the polyamide membranes enhanced from32.9 to 59.6 L/m2 h and anti-fouling results proved that excellent fouling resistance. Thus, chitosan as asecondary modifier has special potential to improve the performance of polyamide membranes.
