The Oxidation Index: A Tool for Controlling the Activated Sludge Process
A common approach to controlling the activated sludge process involves adjusting the amount of biomass in the system according to season. The difficult determination of how much to increase or decrease the mean cell residence is based, in part, on the wastewater treatment plant capacity required to adequately treat the influent wasteload. This article evaluates the oxidation index (OXI), a relatively simple process control parameter that can be used as a basis for making such decisions.
