BW-8040 membrane element is a helically wound composite polyamide membrane element for brackish water treatment. These membranes are characterized by high operating feed pressure, typically 225psi (1.55MPa), and high salt removal (especially suitable for removal of TOC, SiO2, etc.), above 96.5%. These membranes are specially designed for industrial water treatment applications (NaCl ≤ 10,000ppm, salt content ≤ 6000us/cm), such as electronics factories, power plants, petrochemical, coal chemical, etc. that deal with brackish water and high salinity.
