The Lisboa series laminated filters are made of polyester resin and fiberglass with a glossy finish.
Filtration is an essential part of overall pool water treatment. This means that the filtration unit alone, without proper chemical water treatment, cannot ensure the required water parameters. Likewise, chemical water treatment alone is not sufficient without filtration.
Principle of FiltrationWater is drawn by the pump from the bottom of the pool through the pool bottom 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 that traps insoluble impurities present 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 directing water into the filter in the opposite direction to the filtration process. |
