Nanofiltration Membranes for Industrial Application
The VNF series nanofiltration membrane element is used to remove organic substances, microorganisms, viruses, and most of the divalent and multivalent metal ions in water, while simultaneously retaining a portion of the sodium, potassium, calcium and magnesium ions. It is a popular choice for use in municipal drinking water, bottle water, food and beverage, medicine, bioengineering, pollution control and other industries.
Applications
The VNF series membrane element features an excellent rejection rate for pesticides, herbicides, TOC and heavy metal ions. The rejection rate of the VNF1 for monovalent ions is relatively low, and the rejection rate of the VNF2 for monovalent ions is relatively high.
