Microbial Fuel Cell Study for the Generation of Electricity Using Waste Water

The resources deficit and the electricity demand have been suddenly increasing. The technologies do have the restrictions due to their energy limit and the cost - intensive for attaining the conversion target of the waste - water recovery. It is necessary to develop a technology that will bring about an alternatives - conventional energy sources in a sustainable way. The current work dealed with the fabrication of a laboratory scale - double chambered microbial fuel cell (MFC) to generate the electricity from the domestic waste water. The experiment was performed to generate the electricity from locally available domestic waste as a substrate using the fabricated MFC. For MFC1, the device was utilised at an anaerobic condition at a different time interval of every 10th day and reading were recorded. For MFC2, the device was set up at varying time interval of everyday and readings were taken. Required graphs of Voltage v/s Current density, Power density v/s Current density were plotted. All the general parameters like Voltage, Current, Current density, Power, Power density shown the maximum values at 20th - day. A sudden reduce in value was observed after 21st - day. The corresponding maximum values are 0.188 V, 18.8 mA, 14674.89 mA/m2, 3.53 mW and 2757.81 mW/m2 respectively. Similarly, for MFC 2, the corresponding maximum values are 1.02 V, 62.5 mA, 8320.02 mA/m2, 63.8 mW and 8486.42 mW/m2 respectively. Thus, this study has revealed that the fabricated MFC can be used for the electrical energy generation from the cow - dung and various other bio - waste.
