Simulation studies for municipal wastewater treatment plants

A simulation study was carried out for the wastewater treatment plant Köln-Stammheim. The core of sludge treatment consist of 5 anaerobic digesters that are operated in parallel under mesophilic conditions. The operator is interested in the improvement of the reduction of particulate organics and the enhancement of gas production. The objective of the simulation study was the model­ling of the current operation control and following the modelling and simulation of 8 operational alternatives. For this study, the mathematical approach ADM1 (Anaerobic Digestion Model No. 1) has been used.
