Abstract

PURPOSE: To provide a fluidic control system, in which amount of activated sludge to be returned to an aeration tank is controlled through measurement of concentration of suspended matters contained in the aeration tank, thereby maintaining the amount of sludge in the tank at an optimal value, and thus it is enabled to make an efficient use of the system.
