Abstract:

Dynamic simulation of activated sludge process is a common tool for wastewater treatment design and optimization. Most activated sludge models predict only the uptake of BOD and nutrients, however, they can easily be supplemented with further information regarding greenhouse gas (GHG) production to predict the generation of components such as CO₂. Many published anaerobic digestion models contain information on generation of gases, including CO₂ and CH₄. Implementing the CO₂-supplented activated sludge and anaerobic digestion models together in a full plant model can provide a useful way to evaluate GHG emissions under a wide variety of operating conditions.
