Abstract
PURPOSE:To improve a rate of operation by providing a means for detecting a differential pressure between the flow inlet side and the outlet side of a filtering apparatus and by outputting a detection signal when a detected differential pressure exceeds a prescribed value, using as a basis the differential pressure at a point of time when the rate of a filtered flow becomes fixed. CONSTITUTION:A differential pressure detector 8 is provided between the inlet side and the outlet side of a filtering apparatus 1 equipped with a filter 2, and a detected differential pressure signal is introduced into an arithmetic unit 9. Based on the differential pressure, the arithmetic unit 9 0calculates a time differential value, and the rate of a filtered flow is determined as fixed when the differential value becomes constant. Using as a reference value the differential pressure detected at a point of time when the rate of the filtered flow is fixed, the clogging of the filter 2 is determined as present. Only when the differential pressure exceeds a prescribed value, a back flow signal is given to a motor-operated valve 7 and thereby back flow water is introduced from the outlet side through a back flow 6, so as to remove the clogging. Accordingly, a backwashing is not performed more than needed, and thus the rate of operation of a system can be improved.
