Abstract

We investigate a model for the activated sludge process. The reactor configuration consists of a single aerated reactor attached to a settling unit. The biochemical processes occurring within the biological reactor is a slimmed-down version of the activated model number 1. The resulting model contains five state variables. We investigate how the stable steady-state solutions of the model depend upon the residence time. From the steady-state solutions we investigate three important process variables: the chemical oxygen demand, the mixed liquor suspended solids, and the total suspended solids.
