Minipore BW-4021 RO Membrane, Active Area 36(3.4) ft2(m2), Minipore (CAT#: STEM-GMAE-4986-LGZ)

BW series reverse osmosis membrane elements have the characteristics of low pressure operation, high permeate flow rate and good desalination effect, and are suitable for desalination of brackish water. In addition, due to its excellent performance in removing soluble salts, TOC, Sio2, etc., it is especially suitable for the preparation of high-purity water in the electronics industry and power industry. It is suitable for the desalination of surface water and groundwater and water treatment with a salt concentration of 2000-8000ppm.
