Removal of all ions contained in the water through cation-exchange elements and anion-exchange elements in a demineralisation water plant or a mixed bed filter.

In the unit for total salt-removal the water is first conveyed over the cation exchange elements and afterwards over the anion exchange mechanism. In this phase different methodes can be applied, which are dependent on the water quality. Quality attainable after passing the demineralisation plant: Remainder conductivity < 2 µS/cm.                                             

In the mixed bed filter the cation-exchange elements as well as the anion-exchange elements can be found as a mixture in a filter bed. The mixed bed exchanger is used for the purification or the final cleansing of the prepared water. Quality attainable after passing the mixed bed filter: Remainder conductivity < 0.08 µS/cm.
