Commercial Series NF Membrane Element

Product Introduction

It hass the selective desalination mechanism for removal of high polyvalent ions(heavy metal ion) and partial maintaining of monovalent ions with health benefits.Moreover,it only needs low operating pressure.

Product details

Usage

It is applicable to the desalination of raw water with salt concentration 500ppm,and it was widely used for small household water purifier,mineral water machine and energy machine etc..
