Utilixation of Nanofiltration Membrane in Water Treatment

Compared to the traditional methods, the nanofiltration membrane applied to water treatment has unique separating performance. It can achieve better treating efficiency, consume less energy, and recycle the useful substances in water. It is widely studied and applied in the drinking water treatment, waste water drainage and reuse treatment. The technical characteristics of nanofiltration membrane were introduced briefly in this paper. The application present situation of treatment by nanofiltration membrane was reviewed in drinking water, sewage and leachates, industrial wastewater and agricultural wastewater. In addition, future prospects on the development of nanofiltration were presented.
