Performance of mediator-less and membrane-less microbial fuel cell (ML-MFC) was evaluated to treat synthetic wastewater and actual sewage. The ML-MFC gave COD and BOD removal efficiencies of 88% and 87%, respectively, and TKN removal was around 45-50%. Biomass granulation was observed in the anode compartment of ML-MFC. Effect of distance between the electrodes and total surface area of anode o...

The potential of using sodium bromate as a cathodic electron acceptor in a microbial fuel cell (MFC) was determined in this study. The effects of sodium bromate concentration and initial catholyte pH on the electricity production of the MFC were investigated. The MFC performance improved with increasing sodium bromate concentration and decreasing catholyte pH. The maximum voltage output (0.538 ...

This study constructed a microbial fuel cell (MFC) using Fe(II)-EDTA catalyzed persulfate as the cathode solutions to decolorize Orange G (OG) and harvest electricity simultaneously. Chelated Fe(2+) could activate persulfate to generate sulfate free radicals (SO(4)(-)) which with high oxidation potential (E(0)=2.6 V) can degrade azo dyes. The influence of some important factors such as pH value...

As an alternative source of renewable energy that has piqued researchers’ interest, Microbial Fuel Cell’s (MFC) limitation low power density requires further development. Various factors affect the performance, but performing all will be costly and time-consuming. Through a combination dynamic steady-state mathematical model modified from past research, effect microbe types towards biofilm form...

A new bioelectrochemical approach based on metabolic activities inoculated bacteria, and the microbial fuel cell (MFC) acts as biocatalysts for natural conversion to energy of organic substrates. Among several factors, substrate is most critical challenge in MFC, which requires long-term stability. The utilization unstable directly affects MFC performance, such low generation. Similarly, intera...

Electrochemical impedance spectroscopy is an efficient, non-intrusive and semi-quantitative technique to characterize the performance of bio-electrochemical systems such as microbial fuel cells and enzymatic fuel cells. Indeed, quantitative interpretation of the impedance data can be obtained with the help of mechanistic models using meaningful equivalent circuits. The production of maximum pow...
