Cluster: Smart Energy Transition Pioneers

Anaerobic digestion of organic waste streams (e.g. manure, food waste or sewage sludge) is a widely implemented biological process that converts complex organic molecules into biogas. In one of the process steps fatty acids formed by one type of bacteria feeds other bacteria cultures to convert this into biogas. A major operational problem is that the multiplication rate of the acid forming bacteria is much higher than that of the biogas forming bacteria. The pH of the reactor will therefore drop drastically and the biogas forming bacteria will be eventually killed which obviously severely impacts process yield.

Can you help us migrate towards a more sustainable resource management of organic waste streams? Create an electronic measurement and control system for an anaerobic digestion reactor and prove how automated analyses of volatile organic acids (FOS) and total alkalinity (TAC, i.e. buffer capacity) can increase biogas production!
