Parametric sensitivity and evaluation of a dynamic model for single-stage wastewater treatment plant

Simulation models of the activated sludge process are believed to be a usef ul tool for research, process optimisation and troubleshooting at full-scal e treatment plants, teaching and design assistance. However, the applicatio n of the models in most treatment plants is limited due to a lack of advanc ed input parameter values required by the models. Although the numbers of t ypical conversion factors and stoichiometric constants are presented in the literature, the range of some parameters is too wide considering the param etric sensitivity of the dynamic model. On the other hand, it is well known that the values of some parameters depend on the nature of a specific wast ewater treatment plant. The present paper is concerned with a dynamic model of the activated sludge process taking place in the single stage wastewater treatment plant with p arametric sensitivity and evaluation. Model calibration was successfully ex perimentally confirmed for the steady-state operational conditions.
