VE water

VE water can have different qualities. The usefulness of VE water in practice, how it can be produced and whether it can have positive or negative health effects, is comprehensively highlighted in this article.

Definition of VE water

VE water is demineralised water. The abbreviation VE stands for "fully desalted".

The occurring in normal tap water ions and salts (including calcium and magnesium, which form the so-called lime in the water) are not present in demineralized water.

Unlike distilled water, however, VE water is not pure. It may also occasionally have additional impurities from the manufacturing process.

It is more aggressive than ordinary water, as it has a much higher solubility due to the lack of salts. Therefore, it is used in many areas - as well as distilled water - as a solvent.

The production of demineralized water is significantly cheaper than the distillation process. It is therefore often used as an alternative to distilled water.

Since calcium and magnesium are also removed by the desalination process using ion exchange systems and mixed-bed filters, it is completely soft water with a hardness of zero.

The absence of charged ions in the water also causes the pH to drop to about the same level as with distilled water. It has a pH of around 5 and is therefore a weak acid.

But, unlike other acids, water is always a weakly buffered acid. That is, as the pH of the environment changes, the pH of the demineralized water changes very easily and very rapidly.

Other names for VE water

VE water is also available as so-called "distillate-like water" in the trade, besides it is also offered as iron or battery water. Distillate-like water is additionally sterilized to completely kill any bacteria that may be present.

Another name for DI water is "demineralized water".


The purity of VE water may vary. The electrical conductivity is used to determine the degree of purity of VE water.

The less salts and ions are present in water, the worse is its electrical conductivity. The electrical conduction in liquids takes place mainly through the so-called electrolytes - that is, dissolved charged ions and salts.

When all the ions and salts are removed, the electrical line works only by way of the so-called autoprotolysis. The conductivity is therefore very low. Since this conductivity value is known, it is possible to deduce the residual content of the ions and salts still present via the measured conductivity.

The unit of conductivity is μS / cm in technical usage. The official SI unit is mS / m - Milli-Siemens per meter.

Application of VE water

VE water is needed above all in the technical area. Its high solvency and high cleanability make it a commonly used solvent in engineering, but also in chemistry and biology. It is often used as an alternative to distilled water.

Also in the operation of cooling circuits, it is used as a heat transfer medium. If the car batteries are not maintenance-free, distilled water must also be added regularly or, as a replacement, also demineralized water.

Most irons require the filling of demineralised water (hence "ironing water"). The completely free of calcium and magnesium VE water thus also leads to no lime deposits in the steam jets and on the soleplate of the iron.

Only some irons have built-in descalers and can also be operated with tap water. This is always to be found in the instructions for use. Such irons should not be operated with demineralized water or distilled water, as this may in some cases suffer from the built-in descaling agent.

Drink of VE water

Due to the absence of minerals and salts, VE water is more aggressive than ordinary water. The minerals in the water normally provide for the buffering of acids in the body and for the maintenance of the acid-base balance in the organism. That's why drinking enough water is so important.

VE water, on the other hand, washes away much-needed minerals from the body. It is only toxic when drinking high amounts (in a healthy normal-weight person from about 17 liters).

Then it flushes out so many sodium ions that it can lead to life-threatening conditions with the sinking of the sodium level in the plasma.

As a "cleanser" for the body, it is not suitable because it mainly flooded minerals and does not remove pollutants and slags.

However, some people swear by the high cleaning power for the organism and drink mainly deionized water, distilled water or osmosis water. However, in the long term, the serious shortage of minerals present in most people in the Western world can be a source of concern and is generally not very recommendable.

Also, because of possible contamination or contamination, a consumption just of deionized water is not advisable, even if it is cheaper than distilled water.

Tips & Tricks

Our organism consists of 70 percent water and therefore relies on the regular supply of natural, mineral-containing water to maintain its function.
