Activated Sludge Model No. 1 (ASM1) was used in the modeling of an activated sludge system treating effluents from an oil refinery. The measurements of the diurnal variation in wastewater flow and composition at the wastewater treatment plant inlet and outlet were carried out.
The calibrated model predicting the influence of changes in the wastewater composition and the operational parameters on the effluent wastewater quality and the related operational costs is available. A calibration technique based on the heuristic method was applied.
The model was used to analyze the influence of changes in wastewater flow and composition as well as different aeration systems on the process performance. The results of dynamic simulations indicate that the verified dynamic mathematical model is a useful supporting tool for optimizing operational parameter values and operational costs.
The presented results are for illustration purposes only and are not intended as instructions for the operation of a wastewater treatment plant.
