Product Description
A nanofiltration (NF) membrane is a type of semi-permeable membrane that filters water and other solutions based on size and charge. It falls between ultrafiltration (UF) and reverse osmosis (RO) in terms of pore size, typically ranging from 1 to 10 nanometers. NF membranes are used to remove divalent ions, some larger organic molecules, and other contaminants while allowing smaller molecules like water and some salts to pass through.
Puri-guard has NF30, NF40, NF60 and NF90 based on different salt rejection and using application. All have its single page to guide you how to choose your right models.
NF60 Membrane Feature
- High selective separation
- Low operating cost
- Long-term stable operation
NF60 Application
- Material concentration and separation
- Separation salt
- Reuse of reclaimed water
- Almost (zero) discharge filed
