The anode is immersed in ,wastewater,, which must be oxygen‐free. Different ,wastewater, types ,can be used, as substrate sources, e.g., brewery ,wastewater, 87, dairy ,wastewater, 88, or municipal ,wastewater, 86. In the latter case, electroactive bacteria are already present and a targeted inoculation of the anodes is therefore not necessary.
