Based on the adoption of object-oriented modelling and simulation tools, in this paper a comparison between the ADM1 and the AMOCO models is investigated, mainly in order to assess the performance of AMOCO for control design. The ADM1 model has been calibrated with reference to the degradation of waste activated sludge, based on literature data, and assumed as reference model. Then, in order to compare the outputs of the two models, some variables of ADM1 have been lumped to match the relevant aggregated AMOCO variables. Since AMOCO failed in predicting the steady state values relevant to the inorganic carbon species and alkalinity, a new version of it has been developed, accounting for the dynamics of the inorganic nitrogen concentration. Steady-state and dynamic simulations based on this new version showed an improvement with reference to simulations obtained with ADM1.

Abstract
Based on the adoption of object-oriented modelling and simulation tools, in this paper a comparison between the ADM1 and the AMOCO models is investigated, mainly in order to assess the performance of AMOCO for control design. The ADM1 model has been calibrated with reference to the degradation of waste activated sludge, based on literature data, and assumed as reference model. Then, in order to compare the outputs of the two models, some variables of ADM1 have been lumped to match the relevant aggregated AMOCO variables. Since AMOCO failed in predicting the steady state values relevant to the inorganic carbon species and alkalinity, a new version of it has been developed, accounting for the dynamics of the inorganic nitrogen concentration. Steady-state and dynamic simulations based on this new version showed an improvement with reference to simulations obtained with ADM1.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
