For the existence of a living organism needs constant water content in a certain amount. Change in the amount of water consumed and its composition may lead to disturbances in the processes of digestion, food absorption, bleeding. Water regulates body heat to the environment, maintains body temperature. The proper balance of water in the body provides that the amount received and the selection of water equally. In case of violation balance may occur violation of life. In almost any water inhabited by various microorganisms (bacteria, viruses, protozoa, algae, fungi).
Among the microorganisms found as harmless, and hazardous to human health. The main health problem associated with drinking water – the presence of pathogens in water. This is due to the fact that infections and viral diseases directly affect the body rights, and various organic and inorganic compounds adversely affect the body after prolonged use of contaminated water. Proper water treatment – not only the guarantee of health of the human body, but also 'Life' in industrial production. There are a number of modern methods of water purification. Mechanical treatment of water or lighting.
May carry out a variety of ways: in the field of centrifugal forces, sedimentation, flotation, filtration, filtration, sound. Finds the greatest use of the filtering process through the mesh fabric, porous materials, filter media. It is caused by low-cost equipment and ease of use. Water purification silver. Silver ions have bacteriostatic and bactericidal properties. At concentrations of 50-100 mg / l silver ions have a bacteriostatic action and have dezinfetsiruyuschie properties. Water purification from iron. Removal of iron – one of the biggest challenges in water treatment. Even from an elementary review of the methods of water purification from iron shows that the one universal economically feasible method treatment, which could be applied in all cases to any water does not exist. Selecting a particular method of iron removal depends on the experience of specialists of the company, which makes water treatment, and the range of equipment, which is used by this company in water purification. Method of water purification using ion exchange resins. Ion exchange using ion exchange resins used in water treatment in the middle of last century. Ion exchange resin – is from small (about a millimeter) beads from polymer materials. Resin beads catch and absorb water from ions of various contaminants, changing them into harmless ions of other substances. Ie by ion exchange, so the resin called ion exchange or ionity. by ion exchange. Ion exchange – a process of absorption of ion exchangers (ion-exchange resins), positive or negative ions "pollution" in exchange for an equivalent number of ion exchanger. Reduction of water hardness. Water softening – the process of reducing the water hardness, ie decrease the concentration of calcium and magnesium ions. The hardness of water – this property of water, defined by the presence of salts in water divalent cations, usually calcium (Ca2 +) and magnesium (Mg2 +). Reverse osmosis. The very process of reverse osmosis as a method of purifying water used since the early 60's. The initial application was for the desalination of sea water. Today on the principle of reverse osmosis in the world produced hundreds of thousands of tons of drinking water per day. uv systems for water disinfection. Disinfection of water – the destruction of microorganisms. Much of bacteria and viruses is delayed in the process of water purification () to 98%. The rest of the microorganisms may contain pathogenic organisms (see micro-organisms in the water), so their destruction is required water disinfection.
