| Abstract: | The composition and properties of natural organic matter,as well as the mechanism of NOM fouling of nanofiltration(NF) membrane, are introduced. And some influential factors, such as the characterization of NOM and NF membrane, pH value, ionic concentration and operating conditions etc., are expounded. As a result, a method of fouling control is put forward, which indicates that the selection of proper parameters and pretreatment of feed water can reduce fouling to full extent and increase the life and improve product water flux at low operating cost. |
