Making demineralized water - how does it work?


Demineralized water is a cheap alternative to distilled water when buying. How to make it in the household and what is necessary for it is explained here. On whether it makes sense to produce demineralized water itself.

Properties of demineralized water

Demineralization means the removal of all natural minerals contained in the water. This may be necessary because the contained minerals interfere technically, or because the water hardness should be reduced to zero.

Due to the removal of all Ca and Mg ions from the water, the water hardness also drops to zero, since the loss of minerals also removes the hardness formers from the water. The pH of demineralized water is clearly in the acidic range (about 5).

Demineralized water is not necessarily free of pollutants and impurities - it is only free of minerals.

Natural demineralized water

Rainwater is natural demineralized water. It rises to the sky as distilled water through evaporation, and on its way back to Earth it does not absorb minerals, as minerals only occur in the soil.

It is not pure, can contain many pollutants, but never contains minerals. This makes rainwater the most cost-effective variant of demineralized water.

Production by osmosis

Reverse osmosis systems also produce demineralised water. When cleaning water, all substances dissolved in the water are filtered out. So that all minerals and hardeners.

Osmosis water is thus demineralized water, as well as distilled water. Both types of water are almost identical in terms of purity.

alternatives

Distilled water can also be produced easily and at no cost. You can also catch it from the in-house Kondenswäschetrockner. This eliminates the need to buy demineralised water or buy an osmosis system.

The purchased deionate may also be contaminated with heavy traces of the ion exchange resins used for demineralization. Distilled water is always clean.

Tips & Tricks

Already with the help of a pot and a glass bowl you can distill water easily.

FAQ - 💬

👉 Demineralization is a purification process that leaves you with clean and pure water. Demineralized water is free from mineral ions and is essential in all industries and laboratories for various purposes.

👉 Demineralized water is also known as deionized or demi water. Ion exchange (anion and cation exchange) - Here, hydrogen ions and hydroxide ions replace the positive ions and negative ions. Electrodeionization - This process works by passing an electric current through the resins to keep them regenerated.

👉 You can demineralise water by passing it through ion exchange resins several times until it is empty. Demineralised water is water completely (or at least to a ridiculously high degree) free of dissolved minerals as a result of one or more of the following processes:

👉 For fresh water applications, demineralization can be a good alternative to distillation, as it is capable of producing water similar in quality to distilled water, but through a more cost-effective ion exchange process. Below we have outlined the most common contaminants treated by demineralizers:
