Description:
The objective of the research described in the report is to apply recent advances in activated sludge process modeling to the simulation of oxygen utilization rates in full scale activated sludge treatment plants. This is accomplished by calibrating the International Association for Water Pollution Research and Control Model and associated SSSP micro-computer software to operating data at six full-scale activated sludge treatment plants. Field data were used to calibrate the key biological parameters contained in the model so that the oxygen utilization rates, dissolved oxygen concentrations, mixed liquor volatile suspended solids concentrations, and process performance simulated by the model matched the corresponding quantities observed in the treatment plants. The results showed that the model and associated software package provide a useful capability to analyze, simulate, and predict oxygen utilization rates. It was possible to obtain reasonable agreement between the measured and simulated values of oxygen uptake rate, dissolved oxygen concentration and other process parameters at most of the plants studied.
