Product Description

The XLP series is a very low pressure aromatic polyamide composite membrane element for surface water and groundwater desalination developed by Walton Technology. It can achieve the same high water flux and high desalination rate as conventional low pressure membranes under very low operating pressure conditions. Its operating pressure is about 1/2 of the operating pressure of conventional low-pressure composite membrane, and the desalination rate can reach 98.0%. Thus reducing the related pumps, pipelines, vessels and other equipment investment. Piping, containers and other equipment investment costs and reverse osmosis system operating costs, improve economic efficiency.

Scope of application

XLP series membrane elements are generally applicable to the treatment of low salinity water sources that do not require high desalination rate, such as surface water, groundwater, tap water and municipal water with salinity less than 1000ppm, etc. They are especially suitable for the second stage desalination of two-stage reverse osmosis. It is mainly used in various fields such as purified water of various scales, boiler make-up water, food processing and pharmaceutical manufacturing industries.
