Removal of sulphate, chloride, and fluoride

The content of sulphate, chloride, and fluoride in drinking water can be reduced by nanofiltration. 

Nanofiltration is applied to purposively reduce unwanted components in full or in part. Nanofiltration applies a pressure typically under seven bar, resulting in lower energy consumption.

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.

Nanofiltration plant NF L3-24 for removal of sulphate in waterworks.
