Product Description

The FR series of contamination-resistant reverse osmosis (RO) membrane elements are aromatic polyamide composite membrane elements developed by Walton Technology for use in complex feedwater conditions. This series of membranes utilizes a special membrane manufacturing process to improve the hydrophilicity, charge and roughness of the membrane surface, thereby reducing the growth and adsorption of contaminants and microorganisms on the membrane surface. The membrane element adopts 34 mil wide inlet flow channel design, which reduces the fouling, lowers the differential pressure of the membrane system, and is easy to clean, which can effectively slow down the membrane contamination and prolong the service life of the membrane element.

Scope of application

Anti-pollution reverse osmosis membrane elements are generally applicable to the desalination of complex feed water with a salt content of 10,000 ppm or less, and are mainly used for the desalination of various lakes and rivers, mine water, municipal reclaimed water, industrial wastewater, RO concentrated water, etc. and the production of pure water.
