Product Description

This Spiral NF Membrane can be bought from us in bulk by our global clients. This membrane is manufactured by our highly experienced technocrats using top notch quality raw materials. The provided membrane has wide use in the dairy operations, water treatment, reclaiming spent caustic solutions, etc. The offered membrane allows to pass the monovalent ions like sodium, chloride and excels in larger or divalent ions. We are an ISO 9001:2008 established firm that can provide our valuable customers top grade Spiral NF Membrane in committed delivery time.

Key points:

  • Power saving techniques
  • Reliable performance
  • Standard dimension
  • Compact built


Usually, NF membrane has a cut-off of molecular weight between 200 to 800 Dalton. It is commonly targeted to eliminate only larger and divalent ions. Monovalent ions such as chloride and sodium will go through a nanofiltration membrane, thus its numerous uses involve groundwater softening, process stream de-salting, and others. 

Also, the NF membrane is becoming widely used in food processing applications like dairy, for immediate concentration as well as partial (monovalent ion) demineralization. NF membrane process press is about 3.5 to 30 bar. Membrane chemistry is: Polyamide, Sulfonate PS, and Sulfonate PES.
