Minipore SW-4021 RO Membrane, Active Area 36(3.4) ft2(m2), Minipore (CAT#: STEM-GMAE-4997-LGZ)

SW series reverse osmosis membrane elements are suitable for seawater desalination. The SW series increases the permeate flow by optimizing the structure of the membrane elements, and requires fewer membrane elements for the same permeate flow. It is characterized by low operating pressure, low equipment investment, good removal rate, reliable performance, high salt removal rate, and only one RO design can ensure the production of drinking water from seawater. It is suitable for the desalination of raw water with a salt concentration of 15000ppm ~ 40000ppm, and the removal rate of boron is over 90%.
