Teaser Partial desalination
For the regeneration of the ion exchangers, CO2-heavy water is prepared and conveyed through the filter beds.

Regeneration of ion exchangers
Providing carbonate for the anion exchanger
A combination of high water hardness and considerable nitrate, chloride or sulphate content can be successfully treated with the Carix process*. The process is based on the combination of a hardness-absorbing weak acid cation exchanger and an anion exchanger which absorbs nitrate, chloride and sulphate. If the two ion exchangers are fully loaded, they are regenerated together and simultaneously by introducing carbonic acid. This saves operating costs and protects the environment.
