IS IT POSSIBLE TO DRINK DISTILLED WATER?

Distilled water is special. We tell you how it differs from drinking water, why it is needed, and whether you can drink it instead of regular water.

What is distillation?

Distillation is the purification of a liquid solution by separating it into its components. They form the word from the Latin distillation, which means “dripping, flowing”. The name accurately reflects the essence of this natural process, which we observe all the time. When soup is boiling, distilled water accumulates on the lid. They also distil melted or rain water.

During evaporation and freezing, water and impurities separate from each other. During boiling, the water evaporates and the impurities remain in the pot. During freezing water, crystallizes first. The impurities are built into the lattice last or remain in the unfrozen water capsule. Therefore salty seawater makes fresh ice, and why clear, clear ice forms on the surface of a muddy puddle.

Of course, naturally distilled water is not perfectly pure. Only unstable magnesium and calcium hydrogen carbonates precipitate out when frozen or boiled. The more persistent magnesium and calcium sulfates can only be gotten rid of with filters or chemicals.

Meltwater from urban snow or rainfall over a modern metropolis can contain harmful microorganisms and chemicals. Absolutely pure distilled water is only got in a laboratory.

what it distils water?

Distilled water is not just very pure water. Ordinary drinking water, even very pure, is essentially a solution: it contains organic substances, mineral salts, alkalis and salts of weak acids. Distilled water does not contain all these impurities.

Roughly , distilled water is pure H2O plus ions and dissolved atmospheric gases (oxygen, argon, carbon dioxide). If you boil it for 30 minutes, the gases will volatilize and we get bi-distilled water. If we purify such liquid from ions, we get deionized water.

Bi distilled and deionized water that has been purified of volatile compounds is called chemically pure and is only made in laboratories.

Properties and application of distilled water

In terms of its properties, distilled water differs significantly from ordinary water. It is completely tasteless and odorless, because the taste and smell of water are given by the salts and organics dissolved in it. It does not conduct electricity as it contains no minerals and therefore no positively or negatively charged particles. For the same reason, distilled water is very soft (PH is 5,4-6,6) and is an excellent solvent.

It directly relates the use of distilled water to its properties. Because of its high purity, it is indispensable for preparing medicinal solutions, conducting analyses and rinsing chemical dishes after washing. I use it in the production of antifreeze, glass cleaners and car cosmetics.

Because distilled water does not form scale when heated, it is used in heating systems and for filling steam irons.

Can I drink distilled water?

Doctors unanimously advise to drink pure water, and what, it would seem, can be cleaner than distilled water? But such excessive purity is more harmful than useful to the human body.

WHO has conducted several studies on the health of people who drink demineralized water or water with low salt content for a long time? They found the following:

  • Demineralized water is less thirst quenching. The person drinks more fluids than usual.
  • Long-term use of demineralized water can lead to a disorder of the water-salt metabolism. This occurs due to a lack of calcium, sodium, potassium and magnesium salts. As a result, an imbalance develops between the amount of fluid entering and leaving the body. Dehydration or hyperhydration appears (text references).
  • Mineral deficiency leads to cardiovascular system malfunction, brittle bones and tooth decay.

If you drink a glass of distilled water, nothing bad will happen to you. Such pure liquid is neutral for the body - there is nothing harmful and nothing useful in it. But we need physiologically wholesome water enriched with mineral salts and fluorine.

And their content depends on the needs of a particular person and is individual. The crews of space stations drink water with different mineral content. It varies from 100 ml/l to 1000 ml/l and is calculated based on the medical parameters of each crew member.
