RO Membrane

Ultra Low Pressure Series

Description

MS Ultra Low Pressure (ULP) series elements are suitable for the desalination of raw water with a salt concentration below 2000mg/L. With high desalination rate, Ultra low operating pressure and large membrane flux, this series of products can be widely used for the desalination of municipal tap water, groundwater and other raw water projects, such ascommunity drinking water, food and beverage enterprises' production water.

Features

High permeate flow and salt rejection under Ultra low pressure
Salt rejection rate up to 99.3%
Removing soluble salts, TOC, SiO2, etc
Decreasing the cost for relevant facilities and operating cost for the RO system

Applications

Pure water production
Boiler feed water
Foodstuff processing
Pharmaceutcal production
