Environmental problems suffering from fossil fuels,trying to find alternative human energy supply and the presence of huge amount of energy in wastewater, considers sewage as an economicallyviableand environmentally-friendly optionsource of energy.Also, wastewater treatment in a localized manner consults reuse of water in the water cycle, but a recovery of wastewater and the return of water to the water cycle requires lots of energy.

Using microbial fuel cells as a solution to this path is considerable andwastewater treatment, using these types of fuel cells, would make it possible to generate the energy required by the system.
