Principle of Filtration

Water is drawn by the pump from the bottom of the pool through the pool drain (1) and from the pool surface through skimmers /collectors/ (2), via the valve (3) into the filter (5), where it is cleaned. It is then pushed back into the pool through the recirculation nozzles (6). The nozzles are located on the opposite side from where the bottom drain and skimmers are installed. The filter itself contains a sand bed, which traps insoluble impurities contained in the water. After a certain period of filtration, the sand becomes clogged and less permeable to water. It is therefore necessary to backwash the sand. Backwashing or rinsing is carried out by feeding water into the filter in the opposite direction to the filtration process.
