Abstract

Removal of suspended solids by gravitational sedimentation is essential for successful biological wastewater treatment. A laboratory-scale experimental program was conducted to define the effects on suspended solids removal of overflow rate and clear zone detention time, the two most important variables in design of final clarifiers for the activated sludge process. Statistical techniques were used in the experimental design and subsequent data analysis to isolate the significance of the two design variables. It was demonstrated that performance depended significantly on detention period, but the observed relationship between overflow rate and performance was not statistically significant. An economic analysis indicated that deeper clarifiers would be superior to systems in common use.
