Mathematical Modeling of Process Liquor Flow and Acetoclastic Methanogenesis under Mesophilic Conditions in a Two-Stage Biogas Reactor - Optimal Retention Time depending on Acetate Concentration

I. Muha, J. Schneider & G. Wittum
In [11] a general model for biogas plants was developed. The model couples the ADM1, modeling the anaerobic digestion processes, with a two-phase model for seepage flow, modeling the process liquor flow within the reactor. In this approach the biogas reactor is spatially resolved within the mathematical model and, therefore, the spatial variations of all considered quantities can be computed. This aim of this work is to investigate the newly introduced inhibition factor from [11]....
