Reverse osmosis membrane is a liquid phase membrane separation method driven by pressure difference, which can be seen as a reverse effect of permeation. Under the pressure, water molecules in the solution penetrate the membrane, while other molecules, ions, bacteria, viruses, etc. are intercepted to achieve desalination and purification.

RO membrane is mainly used for Desalination of seawater, Desalination to produce deionized water, and Desalination of sewage treatment

What performance indicators should we consider when selecting RO membranes? Usually divided into three factors: desalination rate, Permeater flow rate, and recovery rate.

We take BW30PRO-400 RO membrane exported to the Philippines as an example.

Stable desalination rate is 99.5%

Water production capacity is 10500GPD

Recovery rate is15%
