How to change sand in swimming pool filter sand tank

Generally, the service life of the sand in the sand tank of the swimming pool is 1-2 years. The replacement of swimming pool sand is one of the key points of swimming pool sand tank maintenance. Regular replacement of sand tank sand can not only prolong the service life of the sand tank, but also improve the water quality of the swimming pool and the smoothness of the pipeline. Reason: The main function of the sand tank used in the swimming pool is to filter, and the quartz sand is the main filter material of the sand tank, so the quality of the quartz sand directly determines the filtering effect of the sand tank.

The shape of the quartz sand used for sand tank filtration is a regular hexahedron with eight corners. When the sand tank is stacked, there will be gaps between the corners of each quartz sand. These gaps allow water to pass through smoothly, but impurities larger than the gaps cannot pass through, so that it can play a purifying role. The size of the gap determines the filtration accuracy of the sand tank. When the gap is small, the filtration accuracy is higher, but if the gap is too small, the water output of the entire sand layer will be reduced, thereby affecting the water output of the sand tank.

Therefore, the gap between the quartz sand determines the filtering effect, and the size of the quartz sand and the integrity of the quartz sand directly determine the size of the quartz sand gap. Therefore, it can be known that the size of the British sand and the integrity of the quartz sand are the most important factors for the filtration of the sand tank.
