A structured approach to the modelling of
anaerobic processes has provided an important tool for the integral study of microbial
ecology as well as the investigation of advanced control strategies of high-rate anaerobic
reactors. Models can also be applied to assist engineers in process design. After the
pioneering work of Andrews (1968), simulation modelling of anaerobic digestion has been
intensively developed. The <METHANE> simulation model is an example of detailed models of anaerobic digestion. The choice of our model was aimed at: making the model universal, capable of describing all important factors of the anaerobic process; reducing the dimension of the model to a maximum possible degree. The main feature of the <METHANE> model was a flexible way which allows to select initially the appropriate rate functions, temperature dependence and inhibition impact. Visual model calibration at which the differences between the values of observed and predicted variables were close to a minimum was realized. |
