Demi stations

Water demineralization is based on positive (cation) or negative (anion) ion removal or reduction during the flow of water, firstly through a cation-exchange resin column and then through an anion-exchange resin column. As a result, we obtain water devoid of most of the dissolved minerals.

The quality of water obtained in this process depends on various factors. The notions „high quality of water” and „pure water”, frequently used when discussing deionization of water, refer only to the level of dissolved minerals. The ion exchange process does not reduce the bacteria content in the water. In order to remove bacteria, an additional UV lamp needs to be installed in the system or another solution should be used.

The device consists of columns (cation or anion exchanger), equipped with automatic multi-way heads or a valve system and controllers that ensure maintenance-free regeneration cycles.
