Abstract
PURPOSE: To perform efficient backwash and to eliminate blocking due to clogged filter support member by installing filter support member filled with a lot of balls between a pair of upper and lower porous plates in a filter tank.
CONSTITUTION: As shown by the arrow 48, raw water is guided from inlet 12 into filter tank 10, is filtered by filter material 18, is passed through upper support plate 20, ball-contained chamber 24, lower support plate 22, and is discharged from outlet 14 to the outside. In backwashing of filter material 18, cleaning water is forced to enter the tank 10 from the outlet 14 as shown by the arrow 52, and is passed through the support plate 22, ball chamber 24, and support plate 20. Because the cleaning water passes through fine spaces between many balls 26, the water forms complex turbulent flow. This gives the filter material 18 momentarily and locally strong shearing force intermittently. As a result, deposit is easily separated from the filter material 18. The balls 26 are sent to ball cleaning section 32 by cleaning water coming from the pipe 46 which supplies ball transfer medium. There, the balls are cleaned and returned to the ball chamber 24.
