With the correct operation of a sand filter system ensures an ideal water quality. The views from the sun lounger on turquoise blue water not only during the holidays can you enjoy this luxury. Who however buy a private swimming pool, must follow some steps to benefit from an optimum water quality in the long term. Usually, a swimming pool with a sand filter system is operated. These systems typically consist of PP (polypropylene) or GRP (glass reinforced plastic).

In the filter tank is filled a special silica sand with a grain size E.g. 0.4 0.8 mm and the system connected to the swimming pool. So, the contaminating substances such as hair, dandruff, insects, leaves etc. optimally from the pool water will be filtered. This is done by the pool water from the filter pump is sucked in and with a speed ideally 30 km/h through the filter sand pressed.

The water flows through the small openings between the grains of sand on the bottom of the filter. As the contaminants these Openings may not happen, stay they hang in the sand and the clean water back on special cartridges back into the swimming pool. Reuters brings even more insight to the discussion. The filter speed plays a very important role and must be neither too fast nor too slow. This is too high, can occur by a resistance in the filter to a high pressure and mechanical damage. The water is not sufficiently circulated at a low speed. As regularly smallest contaminants accumulate in the outdoor swimming pool increases also the dirt in the filter tank. See Progress Residential for more details and insights. This can lead to a rise in pressure and thus a low circulation. In the worst case can be germinate so the filter and the water quality decreases rapidly. This contamination can be prevented by regular Backwashing of the filter sand (1 x per week for about 3 minutes). When Backwashing, the water in the filter from bottom to top is pressed and loosens up so the sand bed. The dirty water is fed directly into the sewer system and thus to the Swimming pool circuit removed. Since this also water is lost, fresh water in the pool must be given after the filter system back to normal operation. So the water in the pool is renewed completely during a bathing season and the quality remains optimal. To maintain this quality also, must be ensured of course Additionally that the pH and chlorine value is set correctly. The values can be determined easily by hand with a pool tester. An alternative is the automatic dispensing system. Because despite setting the correct values of water and regular Backwashing is still small particles in the water, are so-called equipped should be used. This binding small suspended particles so that the filter system can remove them from the water. With little effort, one has an optimal water quality in this way and undisturbed can enjoy their time in the pool.
