| Abstract: | In view of the membrane fouling issue commonly occurred during water treatment by nanofiltration and reverse osmosis membranes, the effects of membrane surface hydrophilicity, charge properties, functional groups and roughness on fouling behaviors were discussed for different fouling types including organic fouling, inorganic fouling, scaling and biofouling. The inconsistent results of the previous studies due to the coupling feature of membrane surface properties and the distinct characteristics of foulants were analyzed. Finally, the mechanisms and uncertainty of the influence of membrane surface properties on fouling were summarized. Suggestions were also provided for future related researches and the development of antifouling membranes. |
