What is the use of water?
Sufficient water content is necessary for the performance of its functions by absolutely every cell of the body. Therefore, we experience a feeling of discomfort, fatigue, when dehydration is only 2% of body weight. And when the water content in the body drops by 9%, this will necessarily lead to serious health problems. You will be surprised, but we can not even breathe without water! Inhaled air, before penetrating into the lungs of a person, must be saturated with atmospheric moisture.
Supervisory authorities revealed that more than 800 impurities may be present in the tap water. And most of them do not benefit the body. Moreover, in connection with the further deterioration of the environment, the amount of harmful impurities present in the water continues to increase. The treatment facilities and a layer of land above the groundwater can no longer cope with their purification. To purify drinking water, you have to use scientific knowledge and special techniques.
What are the dangers of impurities in the water?
One of the most common types of water pollution from the tap can be called chlorine. The presence of chlorine can be determined by an unpleasant, but "painfully" familiar smell. Ironically, chlorination in its time helped to purify water from dangerous pathogens of various infectious diseases. However, after a time, chlorination causes other dangerous diseases. As a result of the reaction between chlorine and organic substances dissolved in water, toxic trigalomethanes are formed. They are the cause of the development of cancer and heart diseases, lead to liver and kidney damage, as well as premature aging. Unfortunately, today trihalomethanes become quite ordinary ingredients of drinking water. Therefore, purification of drinking water from chlorine is mandatory! The simplest way is to keep water for several hours. Flying chlorine gradually evaporates out of the water. However, for a complete purification, including from trihalomethanes, various filters should be used.
Many dangerous substances dissolved in water accumulate in our body and lead to the development of chronic diseases with long-term consequences. Here are two of more than 800 harmful chemicals found in drinking water. It's mercury and lead. Mercury is extremely dangerous for any living organism. If mercury from the water of the city water supply must necessarily be removed, then the village wells from it are absolutely not protected. Especially a lot of mercury in groundwater in areas of intensive farming. Infected with water, they feed the cattle and irrigate agricultural land. As a result, mercury accumulates in meat, dairy products and plants. Concentration of mercury can be negligible and pass sanitary control. However, mercury through food enters our body and accumulates in cells. Mercury poisoning often causes skin problems, leads to liver and kidney damage, to tooth loss, is responsible for internal bleeding.
Another heavy metal present in the water is lead. This chemical element is extremely dangerous! Lead has adverse effects on the central nervous and reproductive system, impairs hearing and raises blood pressure. With a high level of concentration, lead causes growth retardation in children, a decrease in learning ability. And also kidney damage and anemia. Children are especially sensitive to lead.
Water from the tap is the source of infections
Water is a universal medium for the transmission of very many infections. Cholera - the most terrible of them in the recent past - unfortunately, has not yet become the property of history. This recently confirmed epidemics in Mykolayiv and Dagestan. With cholera in the severity of the consequences and scope of epidemics in the past, another classic aquatic infection - typhoid fever - was competing. And although major epidemics are no longer in our time, small outbreaks of cholera and typhus do occur. The list of pathogenic microorganisms transmitted with water is continued by bacteria, pathogens of brucellosis, salmonellosis, dysentery and many other infectious diseases. Complete this series of viruses, of which the most famous is the hepatitis A virus.
In the emergence of outbreaks of infectious diseases, poor water purification of the public water supply system is not always to blame. Even well-purified water can be contaminated already in the pipes, on the way to the cranes in our apartments. Particularly great is the probability there, where old, leaking water pipes run near the sewer. And also where the water is fed into the apartments with breaks. In this case, when the water in the pipes is disconnected, a vacuum is created and they suck the liquid from the surrounding soils - with everything that is contained in it.
What kind of drinking water purification should I choose?
If we can not trust the water flowing from the tap, what kind of cleaning is preferable? In most cases, consumers choose bottled water. People somehow believe that we have no other way out. However, buying bottled water is an expensive and not the most convenient way out. It is inconvenient to constantly drag from the store heavy bottles, from which you then have to get rid of. In addition, the quality of bottled water depends on the conscience of the producers. Unfortunately, there are many cases when the declared water quality does not correspond to the actual water quality. In addition, there are cases of fakes of well-known brands. If you still prefer to buy bottled water in stores, purchase products of well-established manufacturers. Do not take the first water, especially for baby food.
When choosing bottled water, be sure to consider its chemical composition. Bottled water is divided into mineral, natural and table water. If you drink mineral water from day to day, mineral substances can accumulate in excessive amounts. And, of course, adversely affect your health. For example, sodium - raises blood pressure. Calcium, if it is received in excess with mineral water, can contribute to the formation of kidney stones. To a large extent, the quality of natural drinking water depends on the quality of the water distribution system and equipment, disinfection and filling technology. And, of course, on the quality of the source itself. Quite often the table water of many producers is a simple tap water, only purified from chlorine.
There is an opinion among the people that water cleanses silver well. Not in vain cutlery covered with silver and gold. Scientists on the one hand confirm the useful properties of silver. On the other, do not recommend to abuse this method of cleaning drinking water from the tap. First, silver does not purify water, it only disinfects. Getting rid of bacteria and germs, you are not protected from harmful impurities. A false sense of security is created. Secondly, to achieve a positive effect, the area of the silver product should be quite large. Thirdly, doctors are not sure of the benefits of silver-oxidized water. There are contraindications for certain diseases.
The most optimal type of purification of drinking tap water is household filters. You control the process yourself and you can be sure that the water is really clean. However, it is necessary to take a responsible approach to the selection of a filter for water purification. In no case can you save on quality! Cheap filters also purify water. But if you do not change it in time, you will get harmful impurities in doubled quantities. Choose an expensive multilevel water purification system for reverse osmosis. How does it work? Initially, tap water passes through a triple pre-filter, removing sediment, rust, soil particles, colloidal particles. And also chlorine, some organic impurities and substances that affect the taste of water. Then the water is filtered at the molecular level according to the principle of reverse osmosis. Chemicals, trihalomethanes, heavy metals, toxins, organic impurities, hundreds of other water-polluting substances are removed and washed away. A high-quality filter provides a hundred percent purification of water from bacteria and viruses. To date, reverse osmosis is the most modern and reliable water purification technology.
After all these amazing transformations, the purest water should have a neutral refreshing taste, which is often compared with the taste of water from a spring or a high-mountain stream. There will be no water - there will be no life on Earth. There will be an empty, cold space. In our power to preserve this miracle from miracles, to protect from constant environmental shocks, pollution. Drink more often purified water. Doctors advise not less than 2.5 liters of fluid per day. And you will be healthy and cheerful!
