Ultra low pressure reverse osmosis ULP series membrane components

Product Details

Product positioning

The ELP series membrane components are suitable for desalination treatment of surface water, groundwater, and municipal tap water with a salt content below 2000 mg/L. They are mainly used in various fields such as packaging water, boiler makeup water, and high purity water preparation in the semiconductor industry.


Product Features

The operating pressure of ELP series membrane components is about 2/3 of that of conventional brackish water membranes, with a desalination rate of 99.5%. It can achieve the same high yield of water and high desalination rate as conventional brackish water membranes under ultra-low operating pressure conditions.
