FR series of anti-pollution Vontron membrane elements is developed by the company for brackish water desalination aromatic polyamide composite membrane components, with low-voltage operation, high water production, desalination good performance characteristics, and because using a special process to film surface treated to alter its charge and smoothness of the film surface, increasing the hydrophilicity of the film surface, thereby reducing the pollutants and microbial contamination of the membrane surface, the membrane elements to reduce contamination, prolong service life. FR series desalination membrane elements for salt content of about 10000ppm below surface water, groundwater, water and municipal water, water, mainly for all sizes of industrial water reuse, power plants and other industrial boiler feed water water treatment, especially for industrial waste water containing a small amount of organic pollutants, urban sewage and micro-polluted water treatment.
