Nanofiltration plant

Nanofiltration is often used for treatment of drinking water and industrial process water.

Reduction of sulphate, chloride, and fluoride Partial softening without use of regeneration chemicals Partial softening and reduction of colour and humus from surface water in e.g. the iron and metal industry and paper mills.

Nanofiltration is a membrane technology, which in its mode of operation and construction is very similar to reverse osmosis. A nanofiltration membrane primarily restrains divalent ions and larger molecules. When it comes to the filtration process, a nanofiltration unit is placed between reverse osmosis and ultrafiltration
