Mathematical Analysis and Update of ADM1 Model for Biomethane Production by Anaerobic Digestion

Modeling anaerobic digestion of microalgae using ADM1.

The coupling between a microalgal pond and an anaerobic digester is a promising alternative for sustainable energy production by transforming carbon dioxide into methane using solar energy. In this paper, we demonstrate the ability of the original ADM1 model and a modified version (based on Contois kinetics for the hydrolysis steps) to represent microalgae anaerobic digestion. Simulations were ...

Application of Anaerobic Digestion Model 1 (ADM1) for Prediction of Biogas Production

Anaerobic Digestion Model 1 (ADM1), developed by the International Water Association (IWA) in 2002 is the first and most advanced model applicable for predicting biogas pro-duction and the dynamic processes involved. The model includes parameters after the dis-integration to define substrates in terms of carbohydrates (XCh), proteins (XPr), lipids (XLi) and inert (XI) fractions. Chemical Weende...

Innovative bioelectrochemical-anaerobic-digestion coupled system for ammonia recovery and biomethane production from ammonia-rich residues

Kinetic modelling of anaerobic digestion with new fractionation using simple model and ADM1

This paper investigates the development of a simple model for the optimization of codigestion not only using the Biochemical Methane Potential (BMP) but also using the degradation kinetics. This study concerns an experimental work on the implementation and the operation of continuous reactors fed with different fruits and vegetables wastes at different organic loading rates. A simple model was ...

Improving Biomethane Production and Mass Bioconversion of Corn Stover Anaerobic Digestion by Adding NaOH Pretreatment and Trace Elements

This research applied sodium hydroxide (NaOH) pretreatment and trace elements to improve biomethane production when using corn stover for anaerobic digestion. Full-factor experimental tests identified the best combination of trace elements with the NaOH pretreatment, indicating that the best combination was with 1.0, 0.4, and 0.4 mg·L(-1)·d(-1) of elements Fe, Co, and Ni, respectively. The cumu...
