Nanofiltration (NF) is a membrane treatment process primarily used to separate dissolved solutes from water.

 
The process of movement of solvent through a semipermeable membrane from the solution to the pure solvent by applying excess pressure on the solution side is called nanofiltration.

 
Nanofiltration (NF) is most commonly known for its use in drinking water purification, particularly with regard to removing salt and other effluent materials from water molecules.
