High Rejection Nanofiltration Membrane Element

Product Introduction

It has the selective desalination mechanism for removal of high polyvalent ions and partial maintaining of monovalent ions with health benefits. Moreover, the equipment operating cost can be reduced effectively with the advantage of low working pressure.

Product details

Usage

It is applicable to the desalination of direct drinking water, spring water, boiler water, also desalination and decolorization of wastewater with high salt concentration.
