Softening by ion exchange – it is better not or the hardness should be set to low (°dH8 to °dH10).
By softening The pH value of the water can be reduced to one to 2 pH valuesAnd the water is also “artificial” with sodium (Na2+), replaced by calcium (Ca2+).
Lecture section | Ion exchanger or softening
Ion exchangers that are regenerated with salt (NaCl) are able to exchange calcium (Ca2+) and magnesium ions (Mg2+) for sodium ions (Na2+). This principle is e.g. B. used in dishwashers to protect the heating elements and avoid “limescale stains” on the dishes.
Water softening systems for non-professional use to soften drinking water use this principle. Occasionally it is also used to prepare small amounts of water, for example for watering flowers or making tea. Every Brita water filter, but also our Aquaphor jug filters, softens the water. We have at the Aquaphor® jug filters the lowest possible softening cartridge Aquaphor® B100-7 filter cartridge selected.
If you already use a softener for your entire house or apartment, I recommend that you set it to a hardness of °dH8 to °dH10. Fortunately, this is adjustable in most softening systems. The best thing to do is to ask your plumber or plumbing specialist.
A similar but good question came here on December 14th. 2016:
If you have a decalcification system in your house that uses salt to decalcify the water, and the filter doesn't filter out the salt, does this have an impact on the water when it goes to electrolysis? Does this then result in a very basic lye and very acidic water, i.e. anolyte and catholyte? And the salt tablets are certainly not the healthiest salt. Can I prevent this somehow?
Answer by Yasin Akgün about softening before the water ionizer
Don't worry about the descaling/ion exchanger. If possible, set the hardness to °dH8-10.
If the flow is low, the highly alkaline water will otherwise taste moody. But if nothing is an issue, there is too little salt.
In the ECA systems, pay concentrations between 4,5 and 7% are used, i.e. much more.
