Mathematical approach for improving the reliability of parameter calibration in modeling of anaerobic digestion processes

Anaerobic digestion is a complex biological process requiring the involvement of a variety of microorganisms. Nowadays, biogas plants are usually operated at relatively low organic loading rates due to fear of overload and failure and the subsequent financial consequences. For example, ten medium-sized agricultural biogas plants in Germany have an average organic loading rate (OLR) of 2.5kg
