The XLP series of extremely low-pressure aromatic polyamide composite membrane elements are designed to deliver exceptional performance under ultra-low pressure conditions. These membranes achieve the same high permeate flow and salt rejection rates as regular low-pressure membranes, making them ideal for desalination of surface water and groundwater. Operating at approximately half the pressure of standard low-pressure membranes, the XLP series achieves a salt rejection rate of up to 99.0%. This efficiency reduces the investment costs for associated equipment like pumps, piping, and containers, as well as the operating costs of the reverse osmosis (RO) system, significantly enhancing economic efficiency.
The XLP series is particularly well-suited for desalinating low-salinity water sources, including surface water, groundwater, tap water, and municipal water, with a salt concentration below 1000 ppm. These membranes are ideal for second-pass desalination in two-pass RO systems and are widely used in applications such as pure water production, boiler water replenishment, food processing, and pharmaceutical production.
