Performance evaluation of microbial fuel cell with sewage wastewater andROconcentrate using composite anode made ofLuffa aegyptiaca

Microbial Fuel Cells (MFCs) are capable of producing bioelectricity using bacteria as catalysts that break down the organic matter present in wastewater (WW). The present work demonstrates the synergistic effect ofLuffa aegyptiaca(LA) combined with graphite plate as anode material on voltage generation as well as pollution removal as chemical oxygen demand (COD). Three different feed combinations of WW and Reverse Osmosis (RO) concentrate that is - Experiment-1 (75:25), Experiment-2 (50:50), and Experiment-3 (25:75) have been considered and their performances are compared with the system without LA in the anode. The result shows that low organic loading rate (OLR) and more RO concentration in feed inlet led to more voltage and normalized energy recovery (NER) that is - 530 mV and 19.51 Whkg(-1)COD(-1), respectively.
