Many people know that a person is 2/3 water. And he will not be able to live long without it, because clean drinking water has a huge impact on the health of mankind. Its quality depends on many factors: the state of the environment, ecology, soil, etc. Pure drinking water is water that does not contain any harmful and mutagenic substances and is safe for human consumption.
Methods for water purification.
For many millennia, people have learned to purify water and developed their skills in this. In the modern world, a number of special filters have already been invented with the help of which you can protect water. Here is a list of both legacy and modern methods:
1. Reverse osmosis https://rolfis.com.ua/shop/filtry-dlya-vody/filtry-dlya-pitevoy-vody/sistemy-obratnogo-osmosa.html. The method is based on the improved ability of the liquid, from which it follows that the water moves to an increased salt concentration. Scientists have created the opposite effect with pressure. The liquid seeps through a very thin membrane, through which all harmful bacteria and substances cannot penetrate. This method is recognized as the most effective.
2. UV filters act on water using rays. The method is based on a photochemical reaction, which cause irreparable harm to the clients of microorganisms, as a result of which they die.
3. Ozonation. The chemical elements of ozone penetrate the membranes of bacteria and other microorganisms and oxidize them. As a result, they cannot continue life and die. This helps to improve the taste, and the water begins to smell much more pleasant.
4. Use of silver ions. A fairly well-known method, since it was used in ancient times, when water was disinfected by holding it in a silver vessel. Nowadays, this method is more advanced, therefore, that silver ions are combined with the shell of harmful microorganisms. But there are those who believe this method is not safe due to the fact that silver is a heavy metal and can harm the human body.
5. Activated carbon as a cleaning agent. It possesses reagents that can effectively purify water from harmful substances. Also helps to eliminate odors and gases.
6. Use of iodine. A small concentration of this liquid does not harm the human body, but is detrimental to bacteria. This helps to quickly disinfect not only on the body, but also in water. And special tablets containing iodine will help to clean it in any conditions.
7. Freezing. This method is based on an interesting chemical law. From which it follows that pure water freezes much slower than liquids that contain impurities. Therefore, when defrosting, water containing impurities will melt faster than pure water, and it can be drained.
8. Boiling. Quite an effective method against bacteria and some gases. Most microorganisms and gases cannot tolerate high temperatures and die or escape. But this method also has some downsides. When boiling, not only gases evaporate, but also the water itself. Due to this, the concentration of harmful salts increases, which can lead to some diseases. There are viruses that can withstand high temperature loads and do not die at high temperatures. Boiling will not get rid of very small particles that are almost invisible to the human eye, so sand and other impurities may remain in the water.
