| Abstract: | The technique of fluctuation of transmitted light can reflect the size and changing state of the coagulation particle through the state of the transmitted light fluctuation, and the detected value R can be used as a control parameter to control automatically the coagulate dosage. The control system of coagulate dosage has had some kinds of control modes, which includes single loop system, cascade system, forward feedfeed back system and forward feed-Cascade system, and the technique has stronger practicability. |
