Water treatment

To bring the water quality into compliance with the requirements of users conducted water treatment coming from a natural water source. This treatment can be carried out on plants or water treatment plants for the needs of utilities, in almost all industries.

To bring the water quality into compliance with the requirements of users conducted water treatment coming from a natural water source

Water treatment is to free it from the coarse and colloidal impurities and salts contained in it, thus prevent the deposition of scale, entrainment salt steam, corrosion of metals, as well as contamination of the processed materials by using water in technological processes.

There are the following main methods of water treatment:

  • clarification (removal from water by coagulation, sedimentation and filtration of colloidal and their suspension of pollution);
  • softening (removal of water hardness by precipitation of calcium salts and magnesium, lime, and soda, or delete them by cation exchange);
  • desalting and desiliconization (ion exchange or distillation in the evaporator);
  • removal of dissolved gases (thermally or chemically), and iron oxides and copper (filtration);
  • biological purification of water from bacteria, viruses and other microorganisms. Currently mainly used chlorine, ozone and ultraviolet sterilization. Conducted experiments with ultrasound;
  • improved organoleptic properties of water (remove there from substances imparting odor water (hydrogen sulfide, chlorine), and a number of organic substances).

For example, water treatment occurs when it is fed into the municipal water supply network. Water pre-disinfected with chlorine or ozone. Treatment of water with ozone has great advantages over chlorination because ozone is a strong oxidant than chlorine. And in addition to this, the excess ozone, dissolved in water, breaks down very quickly and through this ozonated water completely devoid of smell.

Treating water with fluorine is carried out in areas where soils are poor in fluorine. This prevents damage to the teeth and some other diseases in the body.
