There is no life without water on the earth. Everyone needs it: plants, animals, people. For people, it is especially important to eat harmless and clean water, without smell and foreign impurities, without any precipitation. It is pleasant to drink invigorating and clear water.
Where does the water come from?
Water for man is extracted from various natural sources, such as lakes, underground springs, rivers. Water in lakes and rivers represents a great danger to human health, because these sources are contaminated, the content of harmful, pathogenic microbes, bacteria in them is very high. Often in such water there are various chemical compounds.
Before the water comes to be used by people, it passes cleaning at the treatment plant. At first, it is cleared of a large-sized, large-sized debris, then it is the turn of water purification from foam and debris of smaller sizes. Then comes the process of clarification and disinfection of water. In order for it to become colorless, small particles of dirt must be turned into flakes, this is done by adding special substances to the water. Further, the water is filtered out, the filters retard some of the microbes and flakes. The remaining harmful bacteria of microorganisms are killed with chlorine.
Further on, this water is to reach the consumer of the conduits, which for the most part have long served their allotted term, often fail. For this reason, water often flows from the crane, muddy, with various impurities, yellowish, with an unpleasant odor. Takuyvodu must be cleaned before use.
Filters for water purification
Now the most effective and correct way of water purification for drinking is the installation of household filters, which perfectly cope with the job. There are flow filters and storage filters.
In flowing filters, filtration is carried out under the pressure of water, they are connected directly to the tap. They are produced in the form of attachments, which can be inserted both into the water pipe itself and to the tap. There are filters with automatic cleaning of the cartridge, there is also a removable cartridge. All of them polish clean drinking water from impurities, from unnecessary substances, pathogenic bacteria, from various heavy metals.
The filter drive is also good enough, unpretentious, convenient, its price is low. It is a jug, into which a vessel is inserted with a filter. Water enters this tank, passes through the filter, where it is purified. Once the cartridge (cassette) has served the time, it must be replaced with a new one. The purpose of the cassettes is great, because they eliminate water from germs and pollution, they can saturate with water, make it much softer, remove chlorine, iron, manganese. It is necessary to keep the jar clean, regularly flush it and the vessel with a filter. Filtered water should not be stored for long, otherwise it will become infected with microbes. And, of course, they will appear, if the filter is always wet, it must be dried regularly.
Traditional water purification means
The most common is boiling. Boiling kills the invaders of serious diseases, eliminates the salts that are present in the water, make it softer. After boiling, the water, which is located at the bottom of the tank, must be poured, since it is where unnecessary substances settle. Use can be after a little settling. Keep this water in a closed container, avoiding the ingress of dust on its surface. The shelf life of boiled water is not great, since microbes appear very quickly in it. The disadvantages of boiling water is that during the interaction of chlorine and boiling increases the amount of organic salts and impurities that are harmful for health.
Clear drinking water can be settled. To do this, it is necessary to take a clean container of small dimensions, turn it under the tap, so that the water runs for a while. Skip this water, accumulated in the pipes, then dial, do not close at once, in order that the smell of chlorine disappears. Then close, after 6-7 hours of settling, it is ready for use. Long-term storage of this water is not recommended so that bacteria do not appear. Also Do not use all the water, the one that is on the bottom, you need to pour.
Bottled water
Now the choice of water in bottles made of plastic is huge. It can be used for drinking, although there are no guarantees of its harmlessness, since we do not know what plastic was used to make bottles, what water was poured in there, how and where it was stored. After all, it is known that when storing these bottles of narcotics, plastic is destroyed when heated and releases harmful carcinogenic substances. This in turn negatively affects human health.
When purchasing bottled water, carefully study the address of the producer, where the source is located, its name, expiration date, TU or GOST. There are cases of filling bottles with water from a simple water pipe, so when buying, see that it was free of rain and clean, so that the bottle itself did not have any damage, the cork was tightened tightly.
Drink only pure water, it will preserve your health!
