Introduction

Nanofiltration membrane is used to remove organic substance, microorganisms, virues and most of the divalent and multivalent metal ions in water, at the same time to keep part of sodium, potassium, calcium and magnesium ions, it has been widely used in municipal drinking water, bottle water, food and beverage, medicine, bioengineering , pollutiong control and other industries.

Nanofiltration membranes' removal of monovalent ions varies between 50% to 90% depending on the material and manufacture of the membrane.

Application

VNF series membrane element has good rejection rates for pesticides, herbicides, TOC and heavy metal ions. The rejection rate of VNF1 for monovalent ions is relatively low, VNF2 for monovalent ions is relatively high.

Benefits of Nanofiltration Elements

· Good Organic (NOM) Removal

· Partial Softening Preserves Water Character

· Reduced Power Consumption and Costs

· Long Element Life

· Delivers high productivity due to high active area
