Abstract

PURPOSE: To provide the above-identified method, in which the lower limit of returned sludge corresponding to the lower limit of the water level difference leading to breakage of a siphon is calcuated and compared with the actual quantity of the returned sludge so that the quantity of discharged sludge may be controlled to accomplish the activated sludge processing operation in a stable manner.
