Biogas Output

There are many methodologies for improving the biogas output from anaerobic digestion. These techniques include physical (e.g., gas production and feedstock parameters), reactor configuration and chemical parameters (e.g., pH and volatile fatty acid concentrations) within the digester can help to link particular functions and features of the process. Using this expanse of data, mathematical models can be used to understand and forecast the biological process within an anaerobic digester. Such models can then be further developed on a process and biological level to improve their ability to mimic the function of the reactor. This chapter will provide background into modelling and reactor configuration in order to obtain a digital twin of an anaerobic digester.
