Comparison of power generation from restaurant wastewater treatment in microbial fuel cell using carbon felt electrode with carbon paper electrode.

The major aim of this study is to compare the power generation of carbon felt electrode and carbon paper electrode operated Microbial fuel cells (MFC) using restaurant wastewater. Restaurant wastewater samples were collected from MFC with carbon felt electrode (N=13) and carbon paper electrode (N=13) operated for 10 days (G power 80%). Voltage was measured using a multimeter and current, power, power density was calculated from it for both groups. The Power generation was found to be high in MFC operated with carbon felt electrode (410 mW/m²) due to its active surface area, strong conductivity, and good biocompatibility compared to carbon paper electrode (121 mW/m²). The independent sample T-test was done which showed that the power generation of MFC operated with carbon felt electrode (p<0.001) found to be significantly higher compared with MFC operated with carbon paper electrode. The study shows that carbon felt electrode operated MFC is able to achieve higher power generation compared to carbon paper electrode. [ABSTRACT FROM AUTHOR]
