Product Features
CM’s anti-pollution (FR) series membrane elements use a special process to treat the membrane surface, changing the charge and smoothness of the membrane surface, increasing the hydrophilicity of the membrane surface, effectively reducing the fouling of colloids, organic matter and other dirt, and greatly improving the cleaning and recovery performance of the membrane. At the same time, the 34mil wide water inlet flow channel design is adopted to further enhance the anti-pollution ability of the membrane element and better cleanability.

CM’s anti-pollution (FR) series membrane elements have the characteristics of high desalination rate and large flux. They are suitable for desalination treatment of surface water, groundwater, tap water and municipal water with a salt content of less than about 10,000 ppm. They can be widely used in industrial water reuse of various scales, municipal water supply, surface water reuse, coal chemical industry, thermal power boiler feed water and other industrial water treatment. They are particularly suitable for the treatment of industrial wastewater containing a small amount of organic pollutants and micro-polluted water sources.
