In order to study the effect of nitrite and nitrate on the performance of microbial fuel cell, a system combining an anaerobic fluidized bed (AFB) and a microbial fuel cell (MFC) was employed for high-strength nitrogen-containing synthetic wastewater treatment. Before this study, the AFB-MFC had been used to treat high-strength organic wastewater for about one year in a continuous flow mode. Th...

Waste-to-energy is a promising approach for environmental sustainability. We examined the usage of watermelon rind waste coupled with nitrite-containing wastewater electricity production in membraneless biocathode microbial fuel cell (MB-MFC). Results showed that maximum voltage output internal nitrite circulation fed-batch mode was 294 mV, which 1.4 and 1.3 times without continuous mode, respe...

Microbial Fuel Cells (MFCs) represent a still relatively new technology for liquid organic waste treatment and simultaneous recovery of energy and resources. Although the technology is quite appealing due its potential benefits, its practical application is still hampered by several drawbacks, such as systems instability (especially when attempting to scale-up reactors from laboratory prototype...

This study describes and evaluates a computational model for microbial fuel cells (MFCs) based on redox mediators with several populations of suspended and attached biofilm microorganisms, and multiple dissolved chemical species. A number of biological, chemical and electrochemical reactions can occur in the bulk liquid, in the biofilm and at the electrode surface. The evolution in time of impo...

Microbial fuel cells (MFCs) perform wastewater treatment and electricity production through the conversion of organic matter using microorganisms. For practical applications, it has been suggested that greater efficiency can be achieved by arranging multiple MFC units into physical stacks in a cascade with feedstock flowing sequentially between units. In this paper, we investigate the use of co...

Nowadays, the world is experiencing an energy crisis due to extensive globalization and industrialization. Most of sources renewable are getting depleted, thus, there urge locate alternative routes produce efficiently. Microbial fuel cell (MFC) a favorable technology that utilizes electroactive microorganisms acting as biocatalyst at anode compartment converting organic matter present in sewage...

The study combined anaerobic composting of untreated rice straw with V-shaped microbial fuel cell (V-MFC) to investigate the hydrolysis of lignocellulose and electricity generation of V-MFC. Due to the configuration for V-MFC, protons that be generated by the process of lignocellulose degradation could be accumulated with composting liquid at the bottom of V-MFC, and increased the contact area ...

The aim of this study was to determine the relationship between gas produced through in vitro gas production test and microbial fuel cell (MFC) technique and introduce new assay for evaluation of ruminants feedstuffs. The treatments were 1) control diet (without whole cottonseed, monensin and vitamin E; CD), 2) diet containing 20.00% whole cottonseed (CSD), 3) diet including 20.00% who...

Two different microbial fuel cell (MFC) configurations were investigated for electricity production from ethanol and methanol: a two-chambered, aqueous-cathode MFC; and a single-chamber direct-air cathode MFC. Electricity was generated in the two-chamber system at a maximum power density typical of this system (40+/-2 mW/m2) and a Coulombic efficiency (CE) ranging from 42% to 61% using ethanol....

Abstract Background Microbial fuel cell (MFC) technology is a promising sustainable future energy source with renewable and abundant substrate. MFC critical drawbacks are anode surface area limitations electrochemical loss. Recent studies recommend thick biofilm growth due to the synergetic effect between microbial communities. Engineering prospect of MFC. In this study, electrode jacket dish (...
