Abstract This study documented the hydraulic characteristics of typical activated sludge clarifiers. Modifications to the clarifier structures were made in an attempt to improve clarifier hydraulic characteristics and performance. Innovative fluorometric dye tracer studies were used to observe the hydraulic flow patterns within several different types of clarifiers. Factors that are internal and external to the clarifier were found to affect the hydraulic characteristics and performance of the clarifiers investigated.
