Barent filter tank for private pools. The tank is made of fiberglass and is UV-resistant. Sand filters work on the natural principle of water filtration. Water passes through the layer of sand, which captures fine impurities. Over time, the sand becomes clogged and needs to be backwashed, which is what the six-way valve is used for. By turning the valve to the sand washing position, we reverse the direction of water flow and flush the trapped dirt into the waste line. This process can be repeated throughout the entire service life of the sand, which is very long compared to other filtration methods.
Filtration is part of the overall treatment of pool water. This means that the filtration system 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 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 filling, which traps insoluble impurities contained in the water. After a certain period of filtration, the sand becomes clogged and water can no longer pass through it easily. It is therefore necessary to backwash the sand. Backwashing or rinsing is carried out by supplying water to the filter in the opposite direction to the filtration process. |
