Experimental Study of Power Generation and COD Removal Efficiency by Air Cathode Microbial Fuel Cell Using Shewanella baltica 20

Microbial fuel cells (MFCs) are a kind of bioreactor for generating electricity, facilitated by exoelectrogens while treating wastewater. The present article focuses on the performance an air cathode plexiglass MFC in terms chemical oxygen demand (COD) removal efficiency and power output performing two sets experiments. proton exchange membrane electrode materials were Nafion 117 carbon felts, whereas, stable biofilm formation anode surface, pure culture Shewanella baltica 20 was used. Firstly, sterile Luria-Bertani (LB) media containing lactate, ranging from to 100 mM, continuously fed MFC, maximum density 55 mW/m2 observed. Similarly, artificial wastewater with COD 3250 mg/L 10,272 supplied second set In this case, 12 57%, respectively. both cases, hydraulic retention time (HRT) 1.5 h. It found that electricity generation depends characteristics These initial findings confirm design aspects i.e., surface area volume ratio, external resistance respect quality influent need be optimised improve MFC’s performance.
