Abstract：

As a promising separation technology, nanofiltration (NF) plays a more and more important role in various water purification and treatment as well as product separation processes. NF membranes have two typical features that is, sieving effect and electrostatic effect, and are called dense reserve osimosis membranes and ultrafiltration membranes. This paper summarized the progresses on the researches on the evaluation of pore structure and electrical property, the separation mechanism and modeling, as well as the electrokinetic phenomena of the NF membranes over the past two decades. Lastly brief words are mentioned the direction or tendency of the research and development on NF technology in future.
