Ultra low pressure reverse osmosis ULP series membrane components

Product Details

Product Description

The ULP series membrane components are suitable for desalination treatment under low salinity (TDS<1000 mg/L) using municipal tap water and groundwater as water sources. They are mainly used in various fields such as standard residential water supply, pure water preparation, and industrial pure water preparation for food, beverage, etc.


Product Features

It can achieve high water flux under extremely low operating pressure conditions while maintaining a high desalination rate. Its operating pressure is about 30-50% lower than that of conventional brackish water membranes, and the operating energy consumption is reduced by more than 20%.
