Product Line Description
BW-4040 membrane elements are spiral wound, composite polyamide membrane elements for Brackish Water treatment. These membranes are characterized by a high operating feed pressure, normally is 225 psi (1.55 MPa) and result in higher salt rejection rate (especially good for removing TOC, SiO2, etc.), above 99.5%. These membranes are designed for industrial water treatment applications (NaCl ≤10,000 ppm, Salt content ≤6000 µs/cm), such as the treatment of brackish and high salinity waters for Electronic factories, Electric Power plants, Petrochemical industry, Coal chemical industry.
