BW series is an aromatic polyamide composite membrane element. It has the characteristics of low operating pressure, high water production and high desalination rate. It has a high removal rate for dissolved salts, TOC, SI02 and other substances, and is especially suitable for the preparation of high-purity water in the electronics and power industries.
It is suitable for desalination treatment of surface water, municipal water and other water sources, mainly used in industrial pure water, boiler feed water or brackish water applications such as high-concentration brine.

1. Permeate flow rates for individual elements may vary±15%.
2. Membrane active areas may vary ±4%.
3. Stabilized salt rejection is generally achieved after continuous using for 24-48 hours, which depending on feed water qualities and operating conditions.
