Anaerobic Digestion process monitoring and enhanced biogas production - Case Study

The SENTRY system was installed July 2017 at CNETE (Centre National en Electrochimie et en Technologies Environnementales) or National Center in Electrochemistry and Environmental Technologies testing facility in Quebec, Canada. A system was installed in two duplicate Anaerobic Digesters processing waste activated sludge. A pre-treatment step was added to one of the reactors, and the differences between the systems were analyzed using a SENTRY system installed in each. The sensor is demonstrated to be a key tool in understanding the conditions in test and control AD systems.
