Formatted Abstract/Summary
Anaerobic digestion modelling has now reached a steady and broad application base, with publication of approximately 150 articles per year, of which approximately 50% reference the IWA ADM1. This paper reviews changes in application area, and finds that diversity of use has increased, with application by both specialist and non-specialist users, particularly for systems analysis, and identification of underlying process characteristics. However, the three areas of input/substrate characterisation, physicochemistry modelling, particularly in the plant wide context, and application of multidimensional modelling have been identified as key challenges. A systematic methodology for characterising diverse simple and complex substrates is a major barrier to model application. This has been addressed to a limited extent, focused on domestic streams, but needs to be developed further and generalised. Within physicochemistry, the need is broad, but requirements related specifically to plant wide domestic modelling of phosphorous are identified as relating to solid-liquid interactions and the sulfur cycle. This is critical to future phosphorous control and nutrient recovery. Multidimensional modelling is highly important to all areas of anaerobic process application, but barriers are mainly related to accessibility rather than technical issues, and in particular, broader application to solid phase digestion would be highly beneficial to optimisation of design and operation.
