ULP 4040 Membrane


Product introduction

 ULP series: Ultra-low pressure aromatic polyamide composite membrane elements for tap water and groundwater desalination, which can achieve the same high water flux and high salt rejection as conventional low-pressure membranes under ultra-low operating pressure conditions. Its operating pressure is about 2/3 of the operating pressure of common low-pressure composite membranes, thereby reducing the investment costs of related pumps, pipelines, containers and other equipment and the operating costs of reverse osmosis systems, and improving economic benefits.


ULP series membrane elements are suitable for desalination treatment of RO water, groundwater, tap water and municipal water with salt content below 2000ppm. Mainly used in various scales of purified water, boiler feed water, food processing and pharmaceutical manufacturing industries and many other fields
