Water Deionization
Deionization requires the flow of water through two ion exchange materials in order to effect the removal of all salt content. The passage of water through the first exchange material removes the calcium and magnesium ions just as in the normal softening process. Unlike home equipment, deionization units also remove all other positive metallic ions in the process and replace them with hydrogen ions instead of sodium ions. This ion exchange process results in water that is mineral-free.
