Description

The LP22-8040 Reverse Osmosis Membrane is an ultra-low pressure aromatic polyamide composite membrane element designed to deliver high permeate flow, excellent salt rejection, and outstanding performance in brackish water desalination. Operating efficiently at lower pressures, it helps reduce energy consumption while maintaining high-quality purified water production.

The membrane is suitable for a wide range of commercial and industrial Reverse Osmosis (RO) systems. Its excellent rejection of dissolved salts, Total Organic Carbon (TOC), silica (SiO₂), and other dissolved contaminants makes it ideal for producing high-purity water used in the electronics, pharmaceutical, food and beverage, and power generation industries.

Designed for treating surface water, groundwater, municipal water, and other low to medium salinity water sources, the LP22-8040 membrane offers reliable performance, long service life, and consistent water quality.
