How water is purified

Currently, scientists have come to the conclusion that the body begins to age due to the activation of dehydration mechanisms: our cells lose their ability to absorb a sufficient amount of water. This is why the body of older people is only 60-65% water, while the body of a newborn is 90%.

When the amount of water in the cells decreases, they can no longer function effectively. Many chemical processes are impossible outside the aquatic environment. In a healthy body, the amount of water in each cell is fixed. While you can consume a lot of water, you cannot stop the gradual age-related dehydration.

Our body prefers clean drinking water, because this is the kind of water our cells need. Dirty water adversely affects our health. Various pollutants have the most negative impact on our body. So, it can be ions of compounds, solid particles, organic substances, gases dissolved in water, bacteria and their metabolic products. All of these impurities can have a negative effect on human health, for example, reduce immunity or slow down metabolism.

Household water purification

You can purify water at home up to a certain level. If the water does not contain harmful chemical compounds, then it can be purified. To do this, people have come up with a number of simple tricks. True, modern city dwellers hardly know how to purify water at home.

Cleaning methods are usually divided into two groups:

  • cleaning without using filters,
  • cleaning using filters.

Option for water purification without using filters

This method of water purification is the most popular. This is the easiest way to purify water. This does not require any expensive equipment. Normal kitchen utensils are enough.

The simplest cleaning options are:

  • boiling water,
  • settling water,
  • freezing water.

Boiling water

It is quite understandable that when boiling in water, many microorganisms die. Thus, the water can be purified from harmful bacteria, viruses, etc. Also, when boiling, you can get rid of chlorine and some gases, such as radon or ammonia. Of course, this method is hardly too effective. Boiling itself in some cases only adds harmful impurities to the water.

Firstly, boiling leads to the destruction of many nutrients and minerals in the water. Therefore, the water becomes “dead”. Oxygen is also removed from the water during boiling. The longer the boiling takes place, the more intensifies this process of “necrosis”.

Secondly, during boiling, water evaporates, so the content of salts and other harmful substances in it increases. Moreover, salts can settle on the walls of the kettle and enter the human body during the next boil. Salts, as we know, accumulate and have harmful effects on health. As a result, people begin to feel pain in the joints, stones form in the kidneys, the liver suffers, arteriosclerosis appears, etc.

Thirdly, many viruses do not die when boiling, since the boiling point of 100 degrees Celsius is not enough to destroy them. Therefore, water with pathogenic bacteria will remain so even after boiling.

Fourthly, only chlorine, which is in a gaseous state, can be removed from water during boiling. Most of the chlorine doesn’t go anywhere. Moreover, chlorine itself enters into various reactions during boiling, in which various harmful compounds are formed in the water, such as chloroform, which causes cancer.

Thus, while boiling helps to remove some bacteria and harmful impurities from the water, it is still not very effective. Dangerous bacteria and chemical compounds remain in the water. Moreover, in the process of boiling in water, new harmful compounds are formed.

Water sedimentation

This type of water purification is usually used to remove chlorine. To do this, pour water into a large container and leave for a while, 2-3 hours. If the water is not stirred, chlorine will gradually come out of the water.

After settling, the water can be boiled. A combination of these two cleaning options works more efficiently.

Freezing water

This method works better than the two above. Thanks to him, you can rid water of the following substances:

  • phenol,
  • chlorophenols,
  • light organochlorine.

Freezing means the following: you need to pour water into a container and leave it in the refrigerator for a while, until ice forms. Then the water can be thawed and drunk in this form.

Of course, purifying water in this way is quite difficult. This requires a lot of time. This method is based on the fact that when frozen, water itself crystallizes in one place, and impurities, harmful substances, etc., remain in the least cold place. This is why the water should be frozen for as long as possible for this effect to work.

Water filtration

Filtration methods are often used to remove contaminants from water. You can filter water even at home using various nozzles that are at hand.

A great variety of filtration methods have been developed. Usually those that are designed for a specific contamination are effective. If you know exactly what the water is contaminated with, then it can be filtered with great effect.

Ordinary tap water can be as close to clean drinking water as it can be far from ideal. It is the dirty water that needs to be filtered. Modern filters made from innovative materials are able to remove most of the known impurities from the water.

Currently, the following methods of water purification by filtration are popular:

  • deposition of pollutants,
  • clarification,
  • membrane filtration,
  • use of chemical reagents,
  • adsorption of impurities,
  • removal of iron,
  • mitigation,
  • getting rid of salts,
  • conditioning process,
  • disinfection,
  • removal of organic matter,
  • chlorine removal,
  • cleansing from nitrates.

Ozonation as a classic method of water purification

One of the most effective methods of water purification is ozonation. It is used for the massive supply of water to small and large settlements. In Russia, clean drinking water is still not available in all places, but the state is gradually covering the most remote corners of the country with water supply.

A big problem is the appearance of plankton in reservoirs and rivers feeding them. Because of this, water can have an unpleasant odor and specific taste. Other chemical and organic impurities appear in reservoirs due to the release of industrial waste into rivers. Emissions of large industrial giants of heavy metallurgy especially affect the purity of water. So, water near such enterprises may contain the following elements:

  • phenols,
  • pesticides,
  • nitrogen compounds,
  • oil and oil products.

There are frequent cases when, due to accidents at Russian enterprises, poisonous substances leak into the rivers. This has an even worse effect on the quality of water used to supply water to settlements. Manganese and other pollutants are often found in groundwater.

That is why the introduction of treatment into the water supply system is a very important task. However, water purification by standard methods does not work as efficiently as we would like. As a result, ordinary tap water can even contain toxic substances.

The most optimal way to get rid of such problems is considered to be ozonation. It purifies polluted water very well and improves the health of a person who constantly uses such water.

Ozonation is the most widespread purification technology in the production of drinking water today. It is quite simple to use and relatively cheap. Ozonation itself is more effective than other methods for the following reasons:

  • As a result of ozonation, harmful chlorine derivatives are not formed in water.
  • Russia has enough capacity to produce ozone; it can be produced locally.
  • Chlorine must be delivered to the water treatment site.
  • Ozone cleans water better from bacteria and viruses.

It should be noted that ozonation can also be used as an additional purification option after using conventional chlorination. With the simultaneous use of chlorine, hydrogen peroxide and ozonation, it is possible to purify water as efficiently as possible. The subsequent use of ultraviolet light helps rid the water of any harmful microorganisms. Then you can apply ultrasound, pass water through a layer of sand and coal – and the purest drinking water is ready!

The most important advantage of ozonation is its effect on water color. After ozonation, the water returns to its natural transparency. Ozonation also destroys odors and tastes. Thus, it is possible to return the water to its usual taste. At the same time, ozone does not form additional chemical compounds in the input – it simply turns into oxygen.

The ozone treatment also helps remove the earthy flavor from the water. This is due to the fact that ozone reduces the content of geosmin in water tenfold! This improves the taste of the water.

Ozone also disinfects water well. It began to be used for water purification before chlorine, but it was chlorine that became widespread. This is due to the fact that ozonation requires a fairly large amount of energy. In addition, the properties of ozone in water are still not well understood, and filters where ionization and water purification take place are very quickly covered with biomass. The latter slows down filtration, although it does not impair the properties of purified water.

Currently, various technologies are used to prevent biomass from appearing on ionizing filters. For example, oxidizing agents such as chlorine, sodium, acid and chloramine are used.

In general, ozonation is a promising and affordable technology. Its use is advisable for additional water purification along with the use of other methods, including chlorination and ultraviolet irradiation.
