reverse osmosis membrane 8040 LE

BDX8040B-ULP LE reverse osmosis membrane is used for the desalination of low salinity water and other similar water and it has high desalination rate and long time stable performance under high flow and low operating pressure (fall 20-40% compared with common low pressure membrane). BDX8040B-ULP ro membrane is applicable to the water which contains less than 2000ppm salt. It is used to produce pure water or ultra pure water in electronics, power, petrochemical, food, beverage and pharmacy.
