  • Water softening is understood to mean the removal of the alkaline earth cations Ca 2+ and Mg 2+ dissolved in the water, which can reduce the washing action of detergents by forming lime soils and can lead to troublesome scale deposits in pipelines and apparatus. From colloquial hard water soft water is generated. The removal of only calcium and magnesium ions from the water, as is done in dishwashing, would not significantly improve the washing efficiency in a laundry washing process. Detergents are therefore often added so-called water softening chemicals, which enter into strong interactions with the alkaline earth cations, which are then no longer available for disturbing reactions. The alkaline earth cations are not removed from the water. The water then shows within certain limits the behavior of soft water. This process is therefore not actually softening and the disadvantages of hard water remain essentially exist. In addition, the water softener must be removed during the rinse, which rather increases the amount of rinse water needed.
