Application of Mechanistically Inspired Model on Biogas Production at the Biogas Plant

Biogas is a product of the activity of degrading microorganisms on the biodegradable organic matter in the anaerobic atmosphere. In this paper, the application of Anaerobic Digestion Model No. 1 (ADM1) on the anaerobic co-digestion process on biogas plant has been examined. The feedstock for biogas plant is composed of maize silage, animal manure and slurry. Anaerobic digestion process has been conducted under mesophilic conditions in digesters. The model predicts the following components in generated biogas: methane, carbon dioxide and hydrogen. By the correlation of experimental data and model results on the gas phase, the acceptability of model on continuous process has been considered. Estimation of model parameters has been conducted considering experimental data.
