BW (Brackish Water) membrane is an aromatic polyamide composite membrane element for desalting brackish Water developed by Hangzhou E-MEM Environmental Technology co., LTD. BW has the characteristics of low operating pressure, high flux, and high rejection rate. It has a high removal rate for dissolved salts, TOC, SiO2, and other substances, especially for the preparation of high purity water in the electronic and power industries.

XLP (Extra Low Pressure) series is an extremely low-pressure aromatic polyamide composite membrane element developed by Hangzhou E-MEM Environmental Technology Co., Ltd for surface water and groundwater desalination, which can achieve the same high-water flux and high desalination rate as the conventional low-pressure film under the condition of very low operating Pressure. Its operating pressure is about 1/2 of the operating pressure of conventional low-pressure composite membrane, so as to reduce the investment cost of related pumps, pipelines, containers, and other equipment and the operating cost of reverse osmosis system, and improve economic benefits. XLP series membrane elements are suitable for the treatment of low-salt water sources with not high requirements for desalination rate, such as surface water, groundwater, tap water, and municipal water with salt content less than 1000ppm. Mainly used in various scales of pure water, boiler feed water, food processing, and other fields.
