Abstract
The invention relates to a process and a device for enriching water, in particular drinking water, with magnesium ions. In order to enable enrichment of water with magnesium ions in exchange for calcium ions and/or heavy metal ions during treatment of water, and in particular of drinking water, it is proposed according to the invention to pass the water through an ion exchanger which contains a weakly acidic ion exchange material, wherein at least a part of its ion exchange capacity is loaded with magnesium ions.

1-10. (canceled)
A device for enriching drinking water with magnesium ions, comprising an ion exchanger which contains a weakly acidic ion exchanger material, the ion exchanger material being loaded at least to a part of its ion exchanger capacity with magnesium ions and loaded in the range of 70 to 30% of its ion exchanger capacity with hydrogen ions.
A cartridge for use in a water treatment system, comprising:
- a cartridge housing which is insertable into a water treatment system;
- an ion exchanger material disposed in the cartridge housing, the ion exchanger material being loaded at least to a part of its ion exchanger capacity with magnesium ions and loaded in the range of 70 to 30% of its ion exchanger capacity with hydrogen ions.
