Pool safety and pool cleaning are a condition that pool users and pool owners should be sensitive to. The necessary procedures for effective pool cleaning should be carried out step by step, and it should be determined that the pool water levels after cleaning meet the pool regulations. There are two main steps in pool cleaning. In these processes called filtration and disinfection, pool filtration refers to the physical removal of all types of solid materials such as sand, hair and stones. Pool cleaning equipment that plays an active role in filtration can be specified as sand filters. Sand filters have performed the main process of cleaning the pool water from impurities. Sand filters are used to remove solid materials suspended in water, as well as to remove impurities that cause cloudy appearance and cause abnormality in the color of water. Sand filters positioned in the engine room are used with quartz grade Sio2 or fine filler materials made of glass from 0.5 to 1.5 mm. While the filter pump takes the dirty pool water and directs it to the sand filter, the clean water is drained by attaching the impurities to the sand filter to the filling material. Sand filters vary according to the speed of water passage; open sand filter can be listed as low speed sand filter, standard speed filter, medium speed sand filter and high speed sand filter.
