Brief Introduction

K series of special separation nanofiltration membrane is made of special macromolecule materials with molecular weight cut off 200-500 Dalton. It has the characteristics of selective separation for monovalent, divalent and multivalent ions.

PUNF Series is an upgraded version of HK Series and K Series. PUNF series optimized and enhanced the separation layer, supporting layer and water inlet channel, improved water distribution, reduced pressure drop, it has better fouling resistant characteristics and easier for cleaning.

Scope of Application

The special separation nanofiltration membrane is mainly used for the separation, removal and denitrification of monovalent and divalent ions, and the separation and concentration of liquid materials. Nanofiltration membrane separation process has no chemical reaction, require no heating, no phase transformation, no destruction of biological activity, no change in flavor and fragrance, so it is more and more widely been used for separation, concentration and purification process of food, pharmaceutical, bioengineering and other industries.
