A MULTISCALE INVESTIGATION OF BIOGAS PRODUCTION IN ANAEROBIC REACTORS
The biogas produced in anaerobic wastewater treatment processes is a clean and renewable energy, from both energetic and environmental point of view. Then, how to improve the conversion efficiency of the organics to biogas becomes one of major objectives for an anaerobic reactor involving typically three phases: wastewater, sludge granules and biogas bubbles. Usually, the related study could be conducted respectively at microorganism level by means of microbial technology or at reactor level with conventional global methods. Nevertheless, these two approaches have obvious drawbacks. The former cannot yet represent the complex reality in full-scale reactors. In contrary, the latter approach is too global as the reactor is considered as a black box without a reasonable understanding of various fundamental mechanisms involved.
