Abstract
PURPOSE: To simplify the data operating mechanism by determining the optimum filtering discharge setting value in accordance with the discharge set for the raw water to the process and the tendency of the change of water level of the raw water tank and the relative level position of the upper limit and the lower limit of the setting water level of the raw water tank for storing the raw water.
CONSTITUTION: By the raw water discharge control device 9, the raw water discharge setting value GS from the raw water discharge setting value generator 8 is made equal to the raw water discharge GQ from the raw water flow meter 10 by controlling the raw water discharge control valve 11. In the total filtering discharge target value generator 12, in accordance with the control mode thereof, from the setting value GS transferred from the device 9 or the discharge GQ, the loss of the grit-chamber 1 and the sedimentation basin 2 is subtracted and the total filtering discharge target value RG is added to the total filtering discharge setting value generator 14. Then, by the generator 14, in accordance with the relative level of the upper and the lower limit values of the setting water level of the filter basin raw water tank 3, the total filtering discharge setting value RS is required and the block 7 including the filter basin 4 through the filtering discharge control device 16 is controlled and the block 7 is controlled by the tendency of change in the raw water tank 3.
