Unfortunately, many of us do not even think about the important role drinking water plays for humans. But this unique natural liquid is simply necessary for the creation, maintenance and continuation of life on earth.
Why is it necessary to drink water?
Scientists call water the most valuable product for humans, since our body consists of 60-70% of it. With the help of drinking water, nutrients are transported into the cells of the body, as well as the removal of toxins and other waste products from it. To provide the body with a sufficiently stable thermal regime, each person needs to consume at least 1.5 liters of water per day. If the body loses more than 15% “H2O”, it is threatened with dehydration.
How did water appear on Earth and where does it come from?
About 4.5 billion years ago, our planet was a fireball of gas, which gradually cooled down, enveloped in giant cloud layers. Subsequently, the clouds accumulated quadrillions of billions of tons of water, brought it down to the ground. This is how the “global flood” took place, bringing the planet the “H2O” necessary for life.
Today, about 99.7% of the world’s water resources are ice and salt water. Of these, fresh drinking water, including underground and lake sources, accounts for only 0.3%.
Due to systematic evaporation from oceanic, sea and other water surfaces, clouds are formed in the atmosphere, “discharging” in the form of precipitation, which saturate the spring springs and groundwater. Then, along the numerous river beds, the accumulated resource enters the seas. This is how a new cycle of the water cycle begins.
Water as a chemical and physical object
Water is a binary inorganic compound with the chemical formula “H2O” (hydrogen oxide). Physically, it occupies the largest part of the globe, which is 2.5 times the land surface. There is no pure water without impurities in nature; it is obtained by an artificial method of distillation. This water is called distilled water. Composition “H2O” (by weight): 11.19% “H2” (hydrogen) and 88.81% “O” (oxygen).
Types of water we drink:
- Drinking water is the main water resource suitable for drinking and food preparation, massively delivered to consumers and meeting all regulated quality standards.
- Spring water is an additional water resource of underground origin, suitable for drinking initially or after the necessary treatment.
- Mineral water is a natural water resource containing various trace elements with healing properties.
What does the taste of drinking water depend on and what is it?
- The taste of water depends on three main indicators:
- the presence of certain minerals in the liquid;
- the quantity and quality of organic substances present in “H2O” and the intensity of their decomposition;
- temperature of the substance and the percentage of gases in atmospheric air.
A slightly bitter taste is inherent in water containing an increased amount of sulfates. The predominance of chlorides in this liquid gives it a salinity, and of manganese and iron salts – an iron-like taste.
Water has the maximum refreshing effect at temperatures from 7 to 1100C, and at 150C, its taste characteristics and the ability to fully quench thirst are reduced.
Required drinking water quality
It is a paradoxical fact: water is a vital resource for a person, often becoming the main cause of many diseases.
In this case, the danger can be of various types:
- microbiological: the water contains various microorganisms that cause diseases such as cholera or hepatitis;
- chemical: pollution and poisoning with immediate or delayed effects.
Therefore, drinking water should not only be cleaned of microbiological and chemical pollution, but also taste good.
The main property of water is hardness
One of the important characteristics of water is its ability to dissolve various minerals as it passes through limestone rocks. Hard water contains a large amount of magnesium and calcium salts. It is pleasant to drink, but not entirely healthy. Frequent use of such water can serve as the beginning of the onset of kidney stones. Due to its hardness, it increases the cooking time of products, and when boiled it forms a significant layer of scale.
What is water pollution?
The ingress of harmful biological and chemical elements into the water makes it unsuitable for human consumption. In today’s environmental crisis, pollution can occur at all stages of the water cycle in nature, including the atmospheric layers, where it accumulates in the form of clouds. Also, pollution can be municipal, industrial, agricultural and even natural.
The most dangerous substances that poison water:
- Nitrates are fertilizers used to accelerate the growth of crops. The current level of environmental pollution can lead to an increase in the concentration of nitrates in water by more than 35% of the permissible minimum. The content of such a quantity of harmful substances in “H2O” is dangerous for human health and, first of all, it concerns children.
- Pesticides are toxic chemicals used in agriculture to protect crops from pests and weeds. Such substances enter the water along with rain during the seasonal processing of plants.
- Chlorine is a disinfectant that destroys harmful microorganisms. It is used in municipal water treatment. To carry out disinfection in the water supply network, chlorine is dissolved in large quantities in water, which is why it acquires an unpleasant smell and taste, and also becomes harmful to use. During the First World War, chlorine was used as a chemical warfare agent.
- Lead is the most hazardous to health highly toxic metal, which, dissolving in water, multiplies its harmful effect. It eats well and accumulates in bone tissue. Lead is especially dangerous for pregnant women and children under 6 years of age, since it negatively affects the central nervous system and the formation of the spine. It also promotes the formation of kidney tumors. Old water pipes are the main source of lead water pollution. It should be noted that water is transported through them to apartments after municipal cleaning.
Why do you need to purify water?
In view of the environmental crisis, there is an increase in the number of regions of the Russian Federation (including Moscow) suffering from water pollution by harmful impurities and nitrates. Purification allows us to remove harmful elements from a liquid that is vital for us and return it to its original qualities and taste.
Six existing water quality classes
In Russia, water quality is assessed in accordance with GOST 17.12.04.77 and GOST 17.13.07.82.
- The standards are based on the six-grade water quality assessment system adopted in foreign countries.
- The first and second classes include ecologically sound waters for drinking, recreation, fish farming and irrigation.
- Waters of the third class have similar purposes, however, they can be used for drinking only after preliminary purification.
- The fourth class includes ecologically unfavorable waters that have restrictions in their use for irrigation and fish farming. Such fluids are suitable for technical use.
- The fifth class contains a list of waters that have only a technical purpose.
- Waters of the sixth class are intended for technical purposes with mandatory preliminary purification.
The history of the emergence of devices for water
Since ancient times, the organization of water supply has been an important issue for life. The first structures for water appeared several thousand years before our era in the form of artificial irrigation canals. Since then, people have continued to invent life-making and water-related devices. For example, back in 1804, in the city of Kronstadt, one of the first fully functional water pipelines was built in Russia, and in 1972 the Swedish physicist Anders Celsius introduced a new unit of temperature measurement, the value of which was determined by the properties of water.
To our deepest regret, technical progress has not only positive aspects. Today, technogenic pollution of the environment is a global problem for civilization. The need for clean water has led to an urgent need to create devices for its purification. But, fortunately, each coin has two sides, and with the advent of such devices, daily consumption of purified water has become affordable and most convenient. Today, no one is surprised by the presence in the office or home of a device that cools, heats and soda water.
The prototype of the current cooler was the “drinking fountain” invented by the American Halsey Taylor, who buried his father, who drank contaminated water and died of typhus. Serial production of these devices was started in 1909, and in the 50s, devices for drinking water, to which a cooling system was added, began to be called by the English word “coolers” – coolers.
That is why the company “Vody Zdorovya” has been supplying clean drinking water for several years, supplying people with a source of vitality. You can place your order directly on the website.
