There are various types of swimming pools. Swimming pools differ in function (tropical swimming pool, sauna), size and conditions such as water temperature, cleaning system and water Disinfection mechanism. A division can be made in indoor and outdoor swimming pools.

Swimming pool water treatment

Swimming pool water must undergo treatment, in order to remain clear and clean, free from harmful substances, bacteria, viruses, algae and other pathogens and suitable for use by swimmers.

Purification steps

Swimming pool water is treated by means of various purification steps (figure 1). The water is first transported from swimming pools to a water purification plant (1). In the water purification plant, it will flow through a hair removal filter (2), which removes raw pollutions, such as hairs, plasters and leaves, from water. After that, a flocculant (3) is added, which causes smaller colloids to bind together. Colloids are visible floating particles of organic matter, such as skin tissue and textile fibers. This group of pollutants also concerns colloidal pollutants, such as saliva, soap remains, cosmetic products and skin fats. When these pollutants are abundant, they cause turbidity.
