Effective real time process control of activated sludge systems subject to transient loadings is dependent upon the identification of sensitive control parameters. Soluble organic concentration is shown not to be a suitable control parameter. Oxygen uptake rate and, correspondingly, reactor dissolved oxygen concentrations are extremely sensitive to changes in reactor soluble BOD concentration resulting from loading variations and, as a result, can be used as an indirect measure of soluble organics.
