Nanofiltration (NF)

Nanofiltration is a medium to high pressure-driven membrane filtration process. Generally speaking, nanofiltration is another type of reverse osmosis where the membrane has a slightly more open structure allowing predominantly monovalent ions to pass through the membrane. Divalent ions are - to a large extent - rejected by the membrane. In the dairy industry, nanofiltration is mainly used for special applications such as partial demineralisation of whey, lactose-free milk or volume reduction of whey.
