ABSTRACT

 

As carbon based natural energy supplies are dwindling, other sources of energy are being explored. The need for alternate eco-friendly fuel is growing rapidly with depletion of non-renewable energy resources. Microbial Fuel Cells (MFCs) represent a new form of renewable energy which converts the organic matter into electricity (direct current) by the action of bacteria present in wastewater, while simultaneously treating the waste water. Waste management is one of the major areas of concern in today’S environment. In this research both the human needs - treatment of waste water and production of electricity are addressed. The present study was aimed at designing a MFC for generation of direct current from the wastewater of Treatment Plant in SRM University and at optimizing the substrate and microbial consortium in the MFC. The substrates used include that of samples obtained from different stages of wastewater treatment plant. The substrate obtained from lamellar separator gave good results with a maximum of 175
