Energy Saving & high Permeability and Strong High Permeability 8040/4040 RO Membrane
ULP aromatic poly-amide composite elements is specially developped for groundwater and surface water treatment. The operating pressure is about 2/3 of the conventional low-pressure brackish water membranes and the rejection rate can reach 99.5%. With higher salt rejection rate, it can also meet the required permeate flow at very low operating pressure.
