Low Pressure Industrial Reverse Osmosis Membrane Elements for Brackish Water
Low pressure industrial Reverse Osmosis membrane elements for brackish water
The aromatic polyamide composite membrane element used for the desalination of medium and low concentrations of brackish water. It has the characteristics of high desalination rate and large flux, and can achieve the same high water flux and high rejection rate under lower operating pressure conditions, and it can reduce the investment costs of related pumps, pipelines, vessels, etc., and operating costs of reverse osmosis systems.
