BMSW-4040 High Desalting Rate Desalination

Seawater desalination reverse osmosis membrane

Applications:

It is suitable for desalination treatment of high concentration seawater and desalination of brackish water with high recovery rate system, which is widely used in seawater desalination projects, and can also be applied in water recovery and zero-discharge projects.

Features:

With very high sodium chloride desalination rate and boron removal rate, which can reduce the cost of water quality to meet customer requirements, as well as a very high degree of chemical cross-linking, the product can withstand more times of chemical cleaning, adapt to the use of high-pressure and high salt concentration of the environment.
