Energy Harvesting from Dairy and Hospital Wastewater Using Microbial Fuel Cell (MFC)
The present experiment is focused on the production of electricity using Double Chambered Microbial Fuel Cell (DCMFC). In the present experimental study Distillery and Sugar industrial wastewater was used as substrate, which were collected from Mymul Nandini Dairy, Nazarbad, Mysore, India and JSS Hospital, Near Agrahara, Mysore, India, were used. The Biochemical Oxygen Demand (BOD) of JSS Hospital wastewater was found to be 62.64 mg/L. The maximum voltage and current obtained from JSS Hospital wastewater were found to be 825 mV and 2.1 mA, respectively, by using Aluminium as electrode. Experiments were also conducted using Dairy wastewater which yielded a maximum voltage of 1000 mV and current of 4.5 mA by using Copper electrode. Higher BOD and COD (Chemical Oxygen Demand) concentrations of wastewaters was found to yield greater current production, on the other hand dilution of wastewater resulted in lower current production.
