Sand
— a device with a filter element in the form of a container that holds fine sand of a special composition. When water passes through, sand retains mechanical impurities, including quite small ones. One of the main advantages of sand filters is their high performance; they cope better with large volumes of water than another popular type - cartridge systems (see below). In addition, filters of this type are reusable - if the sand becomes dirty, you do not need to change anything, just organize a backwash. Among the disadvantages of this variety, one can note the relatively low filtration efficiency (including the inability to cope with chemical impurities), as well as the large size. However, in many cases the latter is not a disadvantage - the size of the filter is still small compared to the dimensions of the tank itself, and such a device is located outside the pool, and you can choose the installation location so that the filter does not create any inconvenience.
