Pool water preparation

Today we will talk about ways to disinfect pool water. It has been reliably established that the water in a swimming pool is biologically active, and every day organic and inorganic substances inevitably enter it, coming from the environment, or being brought in by bathers.

If nothing is done, then very soon the water will become cloudy, because it is not treated, in the pool, it is an ideal environment for the growth of bacteria and algae.

Even good tap water can quickly turn your pool into a small swamp:

  • After filling the pool with ordinary water, after 2-3 days you will notice that its walls are covered with mucus, and a film has appeared on the surface. This plaque was formed due to the activity of bacteria, which appeared due to the fact that the water was not disinfected.
  • You will also notice that the water has acquired a green tint, which gives it the presence of algae..
  • If your tap water is also relatively hard, you will soon notice that the walls are rough. In this case, the lime contained in the water is deposited on the walls in the form of crystals.
  • And after a few days, the water in the swimming pool will become completely green, it will acquire an unpleasant odor, growths will appear on the bottom and walls of the pool – this is the action of bacteria and decaying algae.
  • However, with the help of a set of physical and chemical treatment measures, it is possible to ensure that for a long time the water in the pool is in an impeccable condition, remains crystal clear, and also does not have an unpleasant odor..

    The main stages of water treatment:

  • Mechanical cleaning – a mesh filter is used to trap debris, hair, and other coarse insoluble particles;
  • Filtration on pressure bulk filters with sand loading to remove suspended organic and inorganic particles after water treatment with coagulants and flocculants;
  • Disinfection of water using various methods and systems: – reagent treatment with chlorine-containing disinfectants (chlorine, sodium hypochlorite); – ultraviolet; – ozonation;

    Application of germicidal installations

    Irradiation of water with ultraviolet light refers to reagent-free methods of water disinfection. The disinfection effect decreases with increasing water turbidity. Due to the fact that irradiation of water with ultraviolet light does not have a “residual aftereffect”, the use of this method is best combined with a reagent method, for example, with a method of disinfection with sodium hypochlorite, which imparts bactericidal properties to water.

    Ozonation of water

    Ozone is used not only for disinfecting water, but also for its discoloration, that is, destruction of organic substances, and deodorization – elimination of foreign odors in water.

    Compared with chlorination, ozonation has several advantages:

  • Ozone has a higher oxidizing potential than chlorine, therefore it destroys viruses, fungi, bacteria, algae and serves as a reliable barrier against the appearance of any microorganisms;
  • Ozone reacts to pollution 15-20 times faster than chlorine and the amount of ozone is 2.5 times less than chlorine;
  • Ozonation increases the content of oxygen dissolved in the water, which contributes to the return of the freshness, characteristic of pure natural sources, to the water purified by ozone;
  • Ozone, like sodium hypochlorite, does not irritate the mucous membranes and skin of pool visitors;
  • Ozone is produced at the site of its use, in contrast to imported chlorine;
  • Water treated with ozone does not smell of chlorine (although chlorine reagents still need to be added, but in much smaller quantities).
  • Ozone destroys algae.
  • Today, the preparation of water for swimming pools using modern technologies and high-quality equipment is not an element of prestige, but an urgent need..
    With the help of modern technologies and the main generally accepted stages of water treatment, it is possible to bring the water of swimming pools to a safe and pleasant state for bathers.
