BDX8040B-400 membrane element 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 flowand low operating pressure (fall 20-40% compared with common low pressure membrane). It is used to produce pure water or ultra pure water in electronics, power, petrochemical, food, beverage and pharmacy.
