Minipore ULP-4021 RO Membrane, Active Area 36(3.4) ft2(m2), Minipore (CAT#: STEM-GMAE-4991-LGZ)

ULP series reverse osmosis membrane elements can work under ultra-low pressure to achieve high permeation flow rate and high salt discharge that can be achieved by conventional low-pressure membrane elements, and are suitable for desalination of surface water and groundwater. Its operating pressure is about two-thirds of the operating pressure of conventional low-pressure composite membranes, and the salt removal rate is as high as 99.5%, which reduces the investment cost of pumps, pipelines, containers and other related facilities. And reduce the operating cost of the RO system, thereby improving economic benefits. It is suitable for the desalination of municipal water and groundwater with a salt content below 2000ppm.
