Brackish RO Membrane BW8040
Brackish RO Membrane BW-8040 is a low pressure reverse osmosis membrane element , and is an aromatic polyamide composite membrane element used for brackish water desalination. It has the characteristics of low pressure operation, high water production and good desalination performance. It has a good removal effect on TOC, SiO2, etc. It is especially suitable for the preparation of high-purity water in the electronics and power industries.

Brackish RO Membrane BW-8040
1. Description :
The BW-8040 / BW-4040 elements can separate salts from water and increase permeability while greatly improving salt rejection. This product is ideal for large industrial and municipal water treatment systems.
BW-8040 / BW-4040 elements reduce desalination costs by increasing energy, efficiency and productivity
2. Suitable for
*new-built or existing RO systems.
*high quality permeate while minimizing unit cost.
*various operating conditions with 4″and 8″elements.
