There has always been a question about purified water and distilled water, whether it is the same or what they are for. We already assume that it is not the same purified water as a distilled one. Next, we are going to explain each water, to see in an easier way its differences:
This type of water refers to when it has received a purification process, making it suitable for human consumption. This water may contain some type of minerals and salts, but that at no time is harmful to our health. In the next section, we will go into more detail about the different ways to purify water.
Unlike purified water, distilled water removes almost all its external elements. This means that it will not have the salts and minerals that it does contain to some extent in purified water. This type of water is obtained by collecting the steam after boiling purified water. Through condensation, we collect this cleaner steam, although its long-term consumption is not recommended as it can cause anemia that is harmful to our health.
Different Ways to Obtain Purified Water
Knowing the difference between distilled and purified water, we are going to see the different methods to achieve the latter. There are up to 8 types of techniques or methods for obtaining it, which we develop in this section and which are compatible with each other to obtain a higher degree of purification:
Chlorine eliminates molds, algae, or some bacteria and maintaining control over pathogenic microorganisms that water may contain. In short, it is a primary type method for water disinfection.
Filtration through an internal bed
As its name indicates, it is a type of filtering system by which the largest particles suspended in the water are eliminated, thanks to different layers of sand with different thicknesses.
Filtration through activated carbon
It is done with a carbon filter, collecting the water that drains as it passes through it. This method absorbs various elements such as sediments or organic compounds, in addition to reducing the smell and taste of chlorine.
Thanks to a paper filter included in the device, this method is able to retain the residues found in the water, down to a size less than a micron. This method will lose effectiveness with use, having to clean it for reuse or change it for a new one.
Through another type of filter called a softener, we can remove a large content of salts from the water, which is colloquially called the hardness of the water. It works through resins that are able to stay with the magnesium, sodium, or calcium particles. They can be both natural and artificial.
Through high pressures, thanks to a semi-permeable membrane, it is capable of separating the water into two types: the one that contains more salts and the one that contains fewer salts. Its function is to eliminate the solids dissolved in it, eliminating up to 99% of bacteria, which is why it is known as ultra purification. If necessary, the water is physically re-polished with a filter that contains a cartridge capable of holding down to one micron or less.
By the action of this type of light on the water, bacteria are eliminated, sterilizing the water.
Ozonation of water
By injecting ozone into the water, it is possible to eliminate the formation of algae in the water and its putrefaction through oxidation combined with the air. Depending on the amount of ozone used and the time they are in contact, a different efficiency will be achieved, being in greater quantity and with a longer contact time, the maximum possible results.
Thanks to current technology, we can get purified water easily, through machines or dispensers and water purifiers.
