The upscaling and performance improvement of the Microbial Fuel Cell (MFC) is being worked on. In order to develop an effective process engineering, new methods are being tested on a 1000 L MBZ. With a more homogeneous process, more efficient energy production from wastewater is achieved. The work also includes the design of a novel MFC reactor type, which is much larger and should exceed the "state of the art". The new MFC reactor is used in particular in energy production from municipal wastewater and cheese wastewater and is characterized by its performance. Wastewater treatment is carried out by microbial electricity production. In alpine farming, this simplifies the disposal of cheese milk. In urban areas, electricity is saved and electricity is produced and at the same time wastewater is purified. Electricity can be supplied to own and external consumption without any effort, regardless of the size of the system.
