Water purification by freezing: truth and myths in the AQUAPHOR blog
The chemical and physical properties of water are so unique that they still give rise to all a guide to digital marketing for architectural firms of myths. You may have heard that if you freeze water and then defrost it again! it will become healthier and cleaner – let’s try to figure out if this is true.
Earth and water
Every day we take a shower! start our morning with a glass of water or coffee brewed with it: water has become such a familiar part of our everyday life that we often take it for granted. But the Earth is the only planet in the solar system where there is water. Scientists are still trying! and still in vain! to find signs of this “elixir of life” on other planets! but it seems that we are the only ones who have hit the jackpot.
By the way! what we drink is not pure hydrogen hydroxide! but! so to speak! a “compote” of various adobe illustrator from scratc elements. For example! tap water cannot but contain chlorine – it is what kills bacteria and makes it safe. It also contains hardness salts in varying concentrations! their excess provokes the formation of annoying scale.
We’ve all frozen water – think of the ice cubes in the freezer – but few have observed the process. The aggregate hindi directory of water changes gradually and unevenly: when it cools! a crust of ice forms on the surface first! and only then do the layers below freeze.
Why does this happen?
In a liquid state! water molecules have energy that is converted into heat. It leaves the surface faster! which is why an ice crust appears.
The impurities contained in tap water have a different structure! they are reluctant to integrate into the crystal lattice of H2O – therefore! the ice crust is formed mainly by water molecules. The impurities “escape” into the liquid layers below! grouping closer to the center. But later the temperature will take its toll! and they will still form a single whole with the ice crystals.
