Product Description:
ULP series ultra-low pressure reverse osmosis membrane element is an aromatic polyamide composite membrane element developed by Walton Technology for desalination of surface water and groundwater.The operating pressure of ULP series membrane element is about 2/3 of the operating pressure of conventional low-pressure composite membrane, and the desalination rate can reach 99.5%. This reduces the investment cost of related pumps, pipelines, containers and other equipment and the operating cost of the reverse osmosis system, and improves the economic efficiency.
Scope of application
ULP series membrane elements are generally suitable for desalination of water sources such as surface water, groundwater, tap water and municipal water with a salt content of about 2000 ppm or less, and are mainly used in a variety of fields such as packaged drinking water, boiler make-up water, food processing and pharmaceutical manufacturing industries.
