Treatment plants are faced with the challenge of stricter regulations andhigher standards for finished water quality. New developments in control strategies and instrument design have overcome some of the previous limitations of monitoring and controlling the coagulation process. This paper describes an online floc analyzer that provides valuable information on the dynamics of particle aggregation subsequent to coagulation. The analyzer can be used online as part of a control strategy to optimize coagulant dosing. The instrument uses fiber optics to measure floc particles in a flowing form floc that is large and easily settled. Fractal analysis has suggested that diffusion and collision of colloidal particles limit particle aggregation, so, proper mixing is a major factor influencing floc formation. Includes 5 references, tables, figures.
