BW series is an aromatic polyamide composite membrane element for desalination of brackish water. It has the characteristics of high water production and good desalination performance. In addition, it has high performance of removing soluble salts, TOC and SiO2, and is especially suitable for the making of high puriffed water in the electronics and power industries.
It is suitable for desalination treatment of surface water, groundwater, tap water and municipal water with salt content less than 10,000 ppm. It is mainly used for industrial pure water of various scales, boiler feed water of power plants and other industrial water. It can also be used for the treatment of brackish water applications such as high concentration saline waste water and beverage water manufacturing.
Features:
1.High desalination rate;2.Good water flux and water production efficiency
3.Excellent flow channel design reduces fouling and blockage problems;
4.Advanced patented permanent hydrophilic technology makes the membrane super anti-pollution.
5.Excellent chemical cleaning resistance
6.Suitable for the treatment of various complex water sources.
