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
