Enhanced MFC Performance Using Vertically Oriented Graphite Electrodes for Voltage generation and Pollution Removal

Abstract

The need for sustainable solutions is highlighted by the growing energy requirements for treating household wastewater (DWW) and the depletion of fossil resources. In order to accomplish simultaneous wastewater treatment and electricity generation, this study investigates the integration of bioreactors with an emphasis on material efficiency. Significant pollutant removal and bioelectricity production were accomplished by the reactor by utilising graphite electrodes, which have high conductivity and durability. The experimental design examined how electrode location and aeration affected performance indicators. The results showed that, thanks to better electron transfer kinetics, aeration greatly increased voltage generation and pollutant elimination efficiency. In order to optimise bioreactor performance and open the door for scalable, energy-efficient wastewater treatment systems, this work highlights the crucial role that materials play.
