Due to increasing population every year, there is a surge in the energy demand globally and exhaustion of non-renewable energy sources to meet the never-ending demands. It has become important to identify and utilise renewable yet cost-efficient energy sources. With respect to the above context, wastewater containing extreme amounts of degradable organic material can be used as the source for generating electric current through a microbial reactor. Electricity is produced due to the anaerobic fermentation of organic/inorganic matter by converting metabolised biomass to complex wastewater using microbes as catalysts, in this process. This project work deals with the operation of reactor using STP wastewater, graphite and carbon plate electrodes under varying conditions of aeration and biofilm. The electricity generation potential of the electrode was tested for different conditions and a maximum of 0.33 V was generated. The maximum Biological Oxygen Demand and removal efficiency of CODof 80% and 70.5% were obtained, respectively.
