BW Series FR Series Membrane Elements
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 purified 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 5,000 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.
FR series, the surface of this membrane was treated by special technology, which changed the electric charge and smoothness of the membrane surface, increased the hydrophilicity of the membrane surface, thus reducing the contamination of pollutants and microorganisms on the membrane surface, and achieving the purpose of reducing the contamination of membrane components and prolonging the service life.
