Nanofiltration

Nanofiltration (NF) is a membrane-based process to effectively remove multivalent ions, pathogens, suspended particles, larger colloids etc. in wastewater and effluent treatment systems.


NF membranes have a nominal pore size of approximately 0.001 microns and an MWCO of 1,000 to 100,000 daltons. In order to obtain clear product water through such membranes, it is necessary to push water at higher operational pressure than Microfiltration (MF) or Ultrafiltration (UF).

Typically operating pressure for NF is near 6-15 barg (600-1500 kPa). Nanofiltration (NF) is an efficient membrane-process for water softning and helps remove hardness from water which makes NF process suitable for a pretreatment to reverse osmosis. 

GreenPebble Technologies provides proprietary NF membrane and membrane systems as part of effluent treatment plant.  

Typical application areas of NF process are as follows:

- Separation and purification of biochemical or biotech components

- Resource recovery for the separation of macromolecular components

- Dyes and intermediate recovery and separation

- Water softning

- Low pressure product separation

- Purification or extraction of flavours, extracts for food and beverage industry

- Zero Liquid Discharge
