RO Membrane

Low Pressure Series

Description

MS Low Pressure (LP) series elements employs independently developed and manufactured Low-pressure-specific polyamide composite membrane sheets. These elements are suitable for desalination of feed water with salt concentration below 3000mg/L. Featuring hgh desalination rates, low operating pressures, and high membrane flux, this porduct is widely appliable to desalination projeccts using municipal tap water, groundwater, and similar sources. Applications include residential direct drinking water and water for production in food and beverage enterprises.

Features

High permeate flow and salt rejection under 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

Typical Applications

Pure water production
Boiler feed water
Foodstuff processing
Pharmaceutcal production
