The ultra-low pressure NF membrane module “LES90” has a high productivity under an operating pressure of 0.5 MPa. The NaCl rejection of “LES90” is 95% and permeate flow is 28m3/day at 0.5MPa. “LES90” is a crosslinked fully aromatic polyamide composite membrane, so it has a high resistance to chemical washing materials. “LES90” can be economically used in the desalination of brackish water and in the concentration of relevant materials from contaminated liquids at food processing plants.
