Residential Series NF 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, home drinking NF1 membrane elements can achieve as the high rejection, ultra-low operating pressure for desalination of raw water with low salt concentration.

Product details

Usage

It is applicable to the desalination of raw water with salt concentration less than 500ppm. It can be widely applied to various small size household water purification, mineral water machine and energy machine etc..
