RO membrane LP22-8040
The LP series of aromatic polyamide compound membrane elements provides low-pressure operation, high permeate flow, and excellent desalination of brackish water. LP series can be effectively used for desalination of surface water (NaCl ≤10000ppm), underground water, tap water, and municipal water.

Due to their excellent performance in removing soluble salts, TOC, SiO2, e.t.c. these membranes are suitable for the production of high-purity water for food and beverages industries, electronic industry and the electric power industry.
