Abstract

PURPOSE: To regenerate filter medium without causing abrasion, by, in passing water upward through a filter tower contg. the filter medium of specified specific gravity, settling the muddy material from the filter medium in the filter tower while the filter medium being stirred up, then by passing water downward after the filter medium is agitated.
CONSTITUTION: The raw water contained in a tank 4 is charged by a pump P1 upward to a filter tower 1, which is packed with filter medium such as PE pellet of a a pellet diameter about 0.5W1.5mm and a specific gravity not larger than 1, in order to capture with filter layer 3 the muddy material which floats and accumulates under an upper water-collecting plate 2. The treated water is discharged through the tower top and a pipe 6 to a tank 7, where it is stored. After filtration for a prescribed time, or when the filter 3 is filled with the captured muddy material and indicates a prescribed head loss, the filtration is stopped and the regeneration is started. The regeneration is carried out by blowing air from a compressor C through a pipe 8 in order to stir the filter medium in the tower.
