Abstract

PURPOSE: To make possible the washing of compact coagulative suspended materials which are difficult to be fined by agitating and washing the particulate filter media by the parallel flow of the air and washing water supplied simultaneously from the lower part of the filter layer and discharging the washing water after sedimentation and separation.
CONSTITUTION: To start the washing of a filter layer 2, a filtering raw water inlet valve 4 and a filtered water outlet valve 6 are closed and an air vent valve 5 and a washing water discharge valve 12 are opened to extract the water to be filtered. Next, the valve 12 is closed and a washing water supply valve 7 and an air blow valve 10 are opened, and a washing water pump 8 and an air blower 9 are operated to eject air and washing water simultaneously from a strainer 3. When the washing water which disturbs and spreads the particulate filter media arrives at the preset liq. level 13 in the upper part of the filter layer 1, the feeding of the washing water and air is suspended and the sedimentation of the filter media is waited, thence the washing water is discharged from the valve 12 to the outside of the filter vessel 1 via an extraction port 14.
