Abstract

PURPOSE: To make the size of a treating water tank smaller and to decrease the number of filter tanks, by installing a raw water feed pump and a feed-increasing pump for common use to a raw water feed pipe which connects plural filter tanks, and by installing a treated water effluent valve for common use to a treated water pipe connecting each filter tank.
CONSTITUTION: A raw water feed pump 14 is operated with feed valve 4A, 4B and a treated water effluent valve 20 opened and with fore-washing valve 11A, 11B and washing exhaust water valve 12A, 12B closed. The raw water is fed to the filter tank 5A, 5B, and the treated water is recovered through the effluent valve 20 to a treated water tank 19. In washing the tank 5A, the raw water feed pump 14 and a feed-increasing pump 16 are operated in order to feed raw water equal in quantity to that of washing water for the tank 5A to the tank 5B and is filtered with valves 4A, 20 closed, and with valves 11A and 12A opened, with the residual valves remained as they are. The treated water in the tank 5B is let to flow through a pipe 18 to the tank 5A, and simultaneously sprayed into the tank 5A through the valve 11A by the operation of a press. pump 21 so as to back and fore wash. Washing waste water from the tank 5A is discharged through a valve 12A.
