Abstract

PURPOSE: To cause a turbidity control unit to respond to disturbance radpily and make it possible to continue operations within a proper range even in case of a faulty turbidity gauge, by performing feed-forward control based on a logical calculation value and by adding a turbidity adjustment signal to the control within a certain limited range.
CONSTITUTION: Original water of turbidity Di is taken in by flow quantity Fi and is branched into two, and one is not processed as it is in the bypass side, and the other has turbidity reduced to turbidity D1 through turbidity reduction unit 4 in the turbidity processing side, and both are mixed to obtain set turbidity Ds. Operation 9 calculates value Fe[(Ds-D1)/(Di-D1)] and leads this output to multiplier 14. Meanwhile, final turbidity D0 is detected and is led to adjustment eauipment 10 and is compared with set turbidity Ds, and the adjustment output is inputted to upper and lower limit limiter 11. Output 0 of limiter 11 is inputted to divider 13 and is divided by set input Y to obtain O/Y, and O/Y is multiplied by the output of operator 9 by multiplier 14, and the obtained value is given as a set value of bypass flow quantity adjustment equipment 15.
