Nanofiltration (NF)

You are here: Technologies > Membrane Filtration > Nanofiltration

The Nanofiltration process is a Reverse Osmosis process using a relatively open RO membrane, allowing water and small univalent ions (Na+, K+, Cl-) to pass.

Typical APV NF applications are:

Dairy

• Whey partial demineralisation and concentration
  • For WPC production dedicated to special applications like baby foods
  • As a pre-treatment for Ion Exchange and Electrodialysis
  • For reducing the salt content of cheddar whey
• Milk partial demineralisation
  • Special market milks
  • Special milk powders
• UF permeate partial demineralisation
  • Fermentation
  • Special applications like baby foods
  • Special lactose powders
