Reduced order model of the activated sludge process dynamics, presented in the paper, can be treated as a compromise between simplicity (needed for control purposes) and complexity (needed for process behaviour description). Proper calibration of reduced order models is a very difficult task. A new strategy of the model calibration for two different-type sequentially controlled processes (sequentially operated continuous process and sequencing batch reactor) is presented. The proposed method accepts typical values of the model parameters and is based on the fitting of the measured process responses by manipulation of only two model parameters: the initial values of heterotrophic and autotrophic biomass concentrations. Discussion of the response fitting possibilities by changes of XBH and XBA in bio-acceptable limits, as well as validation results for experimental data from two pilot plants, show very promising application of the method.
