Nanofiltration (NF)

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