summary:
BW series of brackish water industrial film products have the latest independent research, development, design and production of Nissin Hengli. It is applicable to desalting treatment of surface water, groundwater, tap water and municipal water with salt content less than 10000 ppm; This product can be applied to situations with low working pressure and high requirements for desalination. It is mainly applied to industrial pure water of various scales, boiler make-up water of power plants, large industrial wastewater, heavy sewage treatment and other fields. In order to better adapt to the poor water quality conditions, this series of anti-pollution membrane elements specially adopt the design of wide inlet water channel network, which is easier to clean. At the same time, the membrane surface is specially treated with special technology, which changes the charge and smoothness of the membrane surface, increases the hydrophilicity of the membrane surface, reduces the adhesion of pollutants and microorganisms on the membrane surface, and has stronger anti-scaling and anti-organic and microbial pollution performance, So as to reduce the pollution rate of membrane elements and prolong the service life.
