T1  - Wet biowaste digestion: ADM1 model improvement by implementation of known genera and activity of propionate oxidizing bacteria
JF  - Water Research
N2  - Anaerobic digestion of biowaste not only reduces environmental burden but also plays an important role for sustainable energy supply. For process optimization simulation based on the Anaerobic Digestion Model No. 1 (ADM1) is commonly used.

The ADM1 was extended to include the known three genera of propionate oxidizing bacteria (POB) and the two routes of propionate degradation (methyl-malonyl CoA and C6-dismutation pathway). Kinetic parameters for anaerobic propionate oxidation by single strains of the three propionate oxidizing genera were determined from defined tri-cultures of the POB with hydrogenotrophic and acetotrophic methanogens and implemented into ADM1. The such improved model ADM1xpro was evaluated with operational data from a full scale wet biowaste digestion plant. Predicted amounts of biogas and composition with ADM1xpro (2201 m³ d−1, 68.1 % CH4 and 31.9 % CO2) correlated well with full-scale process data (2171 m³ d−1, 67.5 % CH4 and 31.9 % CO2).
