ro membranes

BDX4040B-1 ro membranes are used for the desalination of brackish water and other similar water and it has high desalination rate and long time stable performance under high flow and low operating pressure. BDX4040B-1 ro membranes are applicable to the water which contains less than 5000ppm salt. It is used to produce pure water or ultra pure water in Electronics, Power, Petrochemical, Food, Beverage and Pharmacy.
