| Abstract: | The definition and categorization of nanofiltration membranes are reviewed simply in this paper. Influence factors of nanofiltration fouling, such as temperature, concentration polarization, concentration,pH value,flow velocity and regime, are surveyed in detail. Four methods to control fouling are classified as:cleaning procedures, changing properties of solution,improving operating methods and modifying the properties of nanofiltration membrane surface, respectively. Moreover,the influencing factors of permeation and rejection of nanofiltration membrane such as the operating pressure,operating time and feeding velocity and so on,were summarized. |
