BW Series Membrane Elements for Bitter Salt Water Reverse Osmosis


Industrial reverse osmosis membrane components

Reverse osmosis membrane


Ultra low pressure reverse osmosis ULP series membrane components

Product Details

Product positioning

The BW series membrane components are suitable for desalination treatment of brackish water, surface water, groundwater, and municipal tap water with a salt content below 10000 mg/L. They are widely used in various scale industrial pure water production, brackish water desalination, and deep treatment of reclaimed water reuse.


Product Features

The BW series membrane components have the characteristics of low pressure operation, high water production, high desalination rate, and durability. At the same time, they have good removal effects on TOC and SiO2 in water.
