Nanofiltration (NF)
The nanofiltration (NF) technology removes mainly divalent ions and larger particles resulting in an extremelyaccurate water filtration process at the ion level.
Nanofiltration systems are used in applications with lower qualitative requirements than those relating to reverse osmosis, e.g. cooling water circuits, swimming pool water treatment, flow reversing and circuit closing.
The plants are used for process water treatment, i.e. partial water desalination for decarbonising, , softening or water recovery from waste water. Other nanofiltration applications include the removal of specific components, i.e. colourants from industrial water, pesticides from groundwater and nitrates.
