The objectives of this powerpoint presentation included: feasibility testing of CAS-T and PDA system forcoagulant determination and floc growth monitoring;evaluation of real-time coagulant control andmonitoring system for the highly changeable qualityof influent; and,optimization of the coagulation/flocculation process. The experimental method is presented, along with conclusions that were: charge analyzing system has made it possible to detect the particlecharge and the coagulant dosage continuously, and can be used to control thecoagulant dosage automatically;coagulant automatic system was allowed to reflect the steep variation ofraw water turbidity and coagulant dosage especially when the turbidity ofraw water is high; photometric dispersion analyzer is a feasible tool in monitoring theflocculation behavior as well as in determining the state of the coagulantdosing; and,charge analyzing system is more effective than that of jar test to removeturbidity, total organic carbon (TOC), KMnO<sub>4</sub> and ultraviolet (UV) absorbance at 254 nm. Includes figures.
