How do reverse osmosis membranes work and what are their characteristics?

Reverse osmosis is mainly known for its application in water purification, mainly for eliminating salt and other sewage components from water molecules. The method was commonly adopted in 1950 for desalination of seawater, when the whole course of action was rather slow and limited to certain laboratories.

A semi-permeable membrane that can only pass water is used to separate pure water from a solution containing solutes, at which point the water on the pure water side spontaneously passes through the semi-permeable membrane and into the solution side. The water level on the solution side rises, which essentially sums up the process of reverse osmosis.

Reverse osmosis membrane characteristics

High desalination rate with desalination effect up to 99.8%; high water yield with stable water quality; high chemical durability and pollution resistance; wide PH range (PH 1~13); can withstand minor residual chlorine leakage accidents.

Our RO membrane is a reverse osmosis membrane produced with new materials. It is suitable for various applications such as desalination of brackish water with a salt content of less than 10,000 ppm, desalination of slightly polluted surface water, and reuse of cooling circulating sewage water, etc. It is widely used and can be selected with confidence.
