Experiments on nonsteady-state operation of the activated sludge process showed that response to transient square-wave loading is nearly immediate, as indicated by changes in mixed liquor suspended solids, substrate utilization rate, and dissolved oxygen. For sludge with good settling properties, only minor increases in effluent suspended solids occurred. Production of an acceptable effluent depended on control of steady-state unit growth rate.
