In overflow pools, the water flows into the peripheral channels located at the edges of the pool, from which it flows into the compensation tank, from where it is sucked into the filtration plant where the quality is checked, filtration is performed.
After that, the water returns to the pool via the return nozzles located on the floor of the pool, and thus the water circulates from the bottom up, which is a better way of circulation. The water is at the level of the edge of the pool, and its appearance gives the impression of a mirror. These pools represent a slightly more expensive and better option, but also the only option when building public pools due to the greater burden on bathers.
In addition to the technical characteristics that characterize these pools, their visual impression is no less important because a pool with an overflow wall for an infinity effect will satisfy even the most demanding aesthetic criteria.
By installing skimmer circulation in the pool, a simpler and cheaper option is chosen for private and residential use. The water from the pool circulates using a skimmer and goes to the filtration plant where the quality is checked, filtration is carried out and possibly heating and disinfection.
The water returns to the pool via the return nozzles located opposite the skimmer. The water level in the pool is lower than the edge of the pool by approx. 10 cm, where surface water is collected by skimmers. Regulating the water level is most often done through a mechanical water level regulator, and through an overflow placed in the skimmer.
