Nanofiltration (NF) Systems

Nanofiltration (NF) Systems are used to remove hardness, bacteria and viruses, as well as in processes such as demineralization, desalination, COD removal and wastewater recovery. In order to accomplish this, water is passed through a semipermeable membrane with 0.001 micron average porosity, using high pressure.

As membrane porosity is larger compared to Reverse Osmosis (R/O) technology, conductivity can be eliminated to a limited extent; therefore, they are used for hardness removal in applications where it is not necessary to eliminate the conductivity.
