Application of the Swimming Pool Backwash Water Recovery System with the Use of Filter Tubes

During the operation of swimming pools, large losses of water from the backwash of swimming pool filters are observed. This water is often discharged into sewers or used to sprinkle sports grounds. The aim of the research was to design and build an installation for purification and recovery of backw...
