Abstract
PURPOSE: To discharge only the air and washing waste water to the outside of the tank and prevent the outflow of filter material by combining a simple separator and a water-sealing tank without any electric meter in the washing of the filtration tank with a combination of water and air.
CONSTITUTION: An air discharge pipe 3 is branched from an upper lid 2 of the filtration tank 1, and its tip 10 is inserted into the water-sealing tank 4. The cyclone separator 6 is provided below the water surface 5 formed by air pressure, and when washing the filtration tank 7 with the combination of water and air, the air is discharged through the air discharged pipe 3 of a filter loss head pipe, where floated filtering material 7 in the tank 7 is returned to the tank 7 by the separator 6 and only the washing waste water 8 is discharged to the outside of the filtration tank 1. Thus, when the washing water is discharged by continuing air blowing during the washing period, defects such as the outflow of the disturbed filter material 7 together, etc., can be eliminated.
