Opis:
A Microbial Fuel Cell is a device where the bacteria can grow on one electrode, they breakdown organic matter and release electrons from it. The bacteria can do this by keeping them separate from the oxygen, and when they release those electrons it creates a potential between the two electrodes of about half a volt and voltage times current is power, and that is how power is generated from it. But MFCs are not restricted to generating power they can also be used to produce biofuels. Process can also be used to extract hydrogen and methane using appropriate membrane between the anode and cathode. Given paper explores this spectrum of scenarios and speculates the possibility of generating power using the Himalayan top soil.

Opis:
Electricity generation from swine wastewater using microbial fuel cell (MFC) was investigated Swine wastewater was collected into a dual-chambered (aerobic and anaerobic) fuel cell. The maximum power output using copper and carbon electrodes were 250.54 and 52.33 μW, respectively, while 10.0 and 5.0 cm salt bridge length between the cathode and anode gave maximum power outputs of 279.50 and 355.26 μW, respectively. Cathodic potassium permanganate and distilled water gave maximum power outputs of 1287.8 and 139.18 μW, respectively. MFCs utilized microbial communities to degrade organic materials found within wastewater and converted stored chemical energy to electrical energy in a single step. The initial bacterial and fungal counts were 7.4×106 and 1.1×103 CFU ml-1. Bacterial counts steadily increased with time to 1.40×107 CFU ml-1 while fungal count declined to 4.4×106 CFU ml-1 after day 60. The decline in microbial counts may be attributed to the time necessary for acclimatization of microbes to the anode. The genera identified were Bacillus, Citrobacter, Pseudomonas, Lactobacillus, Escherichia coli, Aspergillus and Rhizopus. These microbes acted as primary and secondary utilizers, utilizing carbon and other organics of the wastewater. Chemical parameters indicated that the biochemical oxygen demand decreased from 91.4–23.2 mg/L, giving 75% while the chemical oxygen demand ranged from 243.1–235.2 mg/L, representing 3.3% reduction. Although, the metabolic activities of microbes were responsible for the observed degradation, leading to electricity, the overall power output depended on the distance between the anode and cathode ompartments, types of electrode materials and mediators and oxygen reaction at the cathode.

Opis:
With the increasing standard of living, energy consumption increases as well. So, waste production, including wastewater, increases as well. One of the types of wastewater is wastewater from yeast industry. Wastewater from this industry has not only a high pollutants load but it is produced in great amounts as well. Technical devices that can accomplish the wastewater treatment and electricity production from wastewater is a microbial fuel cell. In microbial fuel cells activated sludge bacteria can be used for electricity production during wastewater treatment. The possibility of using the Cu-B alloy as cathode catalyst for microbial fuel cells to wastewater treatment of wastewater from yeast industry is presented in this paper. The reduction time for COD with the use of microbial fuel cell with the Cu-B catalyst (with 5, 10 and 15% amount of B) is similar to the reduction time with aeration. The obtained power (4.1 mW) and the amount of energy (0.93 Wh) are low. But, if one can accept a longer COD reduction time, the obtained amount of energy will allow elimination of the energy needed for reactor aeration.

Opis:
Microbial fuel cells (MFCs) pertain to a kind of modern technology for the direct conversion of chemical energy in organic matter from wastewaters into electricity during the oxidation of organic substrates. A system of continuous MFC was constructed for the treatment of real petroleum refinery wastewater (PRW). The treatment of real PRW, operational performance of the MFC system, biodegradation of furfural, and energy output were investigated in this study. The MFC was inoculated by mixed anaerobic bacteria, with Bacillus sp. as the dominant type, and continuously operated for 30 days. The biodegradation of furfural and phenol, which are the most prevalent toxicants in refinery wastewater, was investigated. The MFC system reached maximum energy outputs of 552.25 mW/m3 and 235 mV. In the anodic chamber, the maximum removal of furfural and phenol was higher than 99%, with biodegradation of organic content reaching up to 95%. This study demonstrated the viability of a continuous-flow MFC system as a green technology for the treatment of furfural-rich real refinery effluents while generating electricity.

Opis:
The possibility to combine wastewater treatment and electricity production can accomplish a microbial fuel cell. Microbial fuel cells use glucose from wastewater as a fuel. In recent years, both production of municipal and industry wastewater increases very much. Municipal wastewater is directed to the wastewater treatment plant. While industry wastewater can be use as a fertilizer. But, both municipal and industry wastewater can be used in the microbial fuel cells. The comparison of powering the microbial fuel cell with municipal and process wastewater from yeast production is presented in this paper. The measurements covered comparison of changes in the concentration of COD in the reactor without aeration, with aeration and with using a microbial fuel cell (powered with municipal and industry wastewater). The results of measurements of COD showed no differences between the microbial fuel cell powered with municipal wastewater and the microbial fuel cell powered with process yeast wastewater. But, the power output is higher with using process yeast wastewater to powering the microbial fuel cell.

Opis:
The possibilities of simultaneous removal of sulfates and heavy metals (Cu, Ni, Zn) from acid mine drainage have been investigated in two-section bioelectrochemical system (BES). The used BES is based on the microbial sulfate reduction (MSR) process in the anode zone and abiotic reduction processes in the cathodic zone. In the present study, the model acid mine drainage with high sulfate (around 4.5 g/l) and heavy metals (Cu2+, Ni2+ and Zn2+) content was performed. As a separator in the laboratory, BES used an anionic exchange membrane (AEM), and for electron donor in the process of microbial sulfate reduction in the bioanode zone – waste ethanol stillage from the distillery industry was employed. In this study, the possibility of sulfates removal from the cathodic zone was established by their forced migration through AEM to the anode zone. Simultaneously, as a result of the MSR process, the sulfate ions passed through AEM are reduced to H2S in the anode zone. The produced H2S, having its role as a mediator in electron transfer, is oxidized on the anode surface to S0 and other forms of sulfur. The applicability of waste ethanol stillage as a cheap and affordable organic substrate for the MSR process has also been established. Heavy metals (Cu2+, Ni2+ and Zn2+) occur in the cathode chamber of BES in different degrees of the removal. As a microbial fuel cell (MFC) operating for 120 hours, the reduction rate of Cu2+ reaches 94.6% (in waste ethanol stillage) and 98.6% (in the case of Postgate culture medium). On the other hand, in terms of Ni2+ and Zn2+, no significant decrease in their concentrations in the liquid phase is found. In the case of microbial electrolysis cell (MEC) mode reduction of Cu2+– 99.9%, Ni2+– 65.9% and Zn2+– 64.0% was achieved. For 96 hours, the removal of sulfates in MEC mode reached 69.9% in comparison with MFC mode – 35.2%.

Opis:
Purpose: Comparative study of various agar-agar (C14H24O9) percentage and different salts concentration in the salt bridge is carried out to check the efficiency of microbial fuel cell. Design/methodology/approach: Dual chambered microbial fuel cell was used for the overall experiments. Anode and cathode chambers were made of 500 ml plastic jar. Salt bridge was fabricated with agar-agar technical and 3 M NaCl in a PVC pipe of 2 cm long. Chemical Oxygen Demand, pH and electrical conductivity of wastewater were examined. Oxygen was supplied in the cathode chamber using the aquarium pump. Voltage (open circuit voltage) was observed using digital multimeter. Graphite rods were used as anode and cathode electrodes. Findings: Salt bridge was constructed of 3 M NaCl with 5, 7.5, 10 and 12 percent variation of agar amounts in MFC. The maximum outputs were observed 301, 306, 325 and 337.25 mV with the variation of agar 5, 7.5, 10 and 12 percentages respectively as well as chemical oxygen demand (COD) removal efficiency was observed 47.92, 56.25, 52.08 and 64.58 percentages respectively. The optimum agar concentration was found to be 12 percent and a maximum voltage of 337.25 mV and COD removal of 64.58 percent was achieved. After the optimization of agar percentage two salts i.e., Sodium chloride and potassium chloride were analysed. This study also reveals that the NaCl salt bridge is more efficient than KCl salt bridge for the same agar concentration. The maximum voltage for NaCl and KCl were 319 and 312 mV respectively. Research limitations/implications: The amount of electricity production is low and field scale implementation is difficult using microbial fuel cell. The research is still on progress in this field. Originality/value: here is very little research with salt bridge and MFC. Comparative study of different mole of salt is available but agar variation is not yet studied.

Opis:
Research about exploitation the potential of waste and sludge increased drastically in the recent years. One of the most promising alternative methods of waste management is Microbial Fuel Cell (MFC), which generate clean bio-electricity using microorganisms. Organic compounds, sewage, municipal solid waste could be used as a source for microbial nutrition. The construction of MFC is one of the most important parameter in laboratory studies and during scale-up. The efficiency of MFC depends on many factors including type of membrane. To obtain optimization in terms of various operating conditions, a prototype of Microbial Fuel Cell with exchangeable membrane was projected and fabricated by additive manufacturing (AM) technology. This novel device allows to research effects of different types of separator membranes. Preliminary research showed possibility to produce 3D printed MFC systems.

The possibility to combine wastewater treatment and electricity production can accomplish a microbial fuel cell. The possibility of wastewater treatment using the Cu-B catalyst with KMnO4 catholyte for microbial fuel cells is presented in this paper. The measurements covered comparison of changes in the concentration of COD, NH4+ and NO3 - in the reactor without aeration, with aeration and with using a microbial fuel cell (with Cu-B cathode and KMnO4 catholyte). The reduction time for COD with the use of microbial fuel cell with the Cu-B catalyst (and KMnO4 catholyte) is similar to the reduction time with aeration. It has been shown that the Cu-B (with KMnO4 catholyte) can be used as cathode catalyst in microbial fuel cells. Unfortunately in this case is needed to constant delivery of catholyte.

Opis:
The constructed wetland integrated with microbial fuel cell (CW-MFC) has gained attention in wastewater treatment and electricity generation owing to its electricity generation and xenobiotic removal efficiencies. This study aims to use the CW-MFC with different macrophytes for domestic wastewater treatment and simultaneously electricity generation without chemical addition. The various macrophytes such as Crinum asiaticum, Canna indica, Hanguana malayana, Philodendron erubescens, and Dieffenbachia seguine were used as a cathodic biocatalyst. The electrochemical properties such as half-cell potential and power density were determined. For wastewater treatment, the chemical oxygen demand (COD) and other chemical compositions were measured. The results of electrochemical properties showed that the maximal half-cell potential was achieved from the macrophyte D. seguine. While the maximal power output of 5.42±0.17 mW/m2 (7.75±0.24 mW/m3) was gained from the CW-MFC with D. seguine cathode. Moreover, this CW-MFC was able to remove COD, ammonia, nitrate, nitrite, and phosphate of 94.00±0.05%, 64.31±0.20%, 50.02±0.10%, 48.00±0.30%, and 42.05±0.10% respectively. This study gained new knowledge about using CW-MFC planted with the macrophyte D. seguine for domestic wastewater treatment and generation of electrical power as a by-product without xenobiotic discharge

Opis:
The performance of microbial fuel cell (MFC) in treating potato waste was evaluated using a two-chamber MFC supplied with potato liquid after mastication of market available fresh potato. Evaluation was conducted based on electricity generation, organic matter removal (CODCr, DOC and volatile fatty acids (VFAs)), and microbial structure on the anode and in the anodic solution of the reactor. Current density exhibited a trend that followed the concentration changes of organic matter in the solution, with its highest value being observed as 208 mA/m2. Effective removal of organic matter was also observed. By the end of the experiment, the removal for total COD reached about 84%. Bacterial structure analysis based on PCR, DGGE and sequencing indicated that more species were developed in the anodic solution than on the anode, with Proteobacteria, Firmicutes and Bacteroides being dominant. Geobacter, a well reported exoelectrogenic species, was found more predominant on the anode than in the anodic solution. The results thus indicated that simultaneous stabilization and electricity generation could be achieved when potato waste is treated in MFC.

Opis:
One of the problems with microbial fuel cells is a low current density of those energy sources. Nonetheless, it is possible to increase the current density by using the catalyst for fuel electrode (anode) - as long as a low cost catalyst can be found. The possibility of wastewater treatment using the Ni-Co alloy as catalyst for MFC’s is presented in this paper. The alloys were obtained with different concentrations of Co (15 and 50% of Co). The increase of current density with Ni-Co catalyst is approximately 0.1 mA/cm2. So, a fundamental possibility wastewater treatment using the Ni-Co alloy as catalyst for microbial fuel cells was presented.
Jednym z ograniczeń w zastosowaniu mikrobiologicznych ogniw paliwowych jest niska gęstość prądu. Istnieje jednak możliwość podwyższenia tej wartości wykorzystując innego rodzaju katalizator elektrody paliwowej. Praca przedstawia możliwość oczyszczania ścieków za pomocą mikrobiologicznego ogniwa paliwowego z wykorzystaniem stopu Ni-Co jako katalizatora elektrody paliwowej. Do badań wykorzystano stopy Ni-Co o różnej koncentracji kobaltu (15 i 50%). Wykorzystując analizowany katalizator uzyskano wzrost gęstości prądu rzędu 0,1 mA/cm2. Wykazano więc możliwość wykorzystania stopu Ni-Co jako katalizatora mikrobiologicznego ogniwa paliwowego.

Opis:
Wastewater has high potential as an energy source. Therefore, it is important to recover even the smallest part of this energy, e.g., in microbial fuel cells (MFCs). The obtained electricity production depends on the process rate of the electrodes. In MFC, the microorganisms are the catalyst of anode, and the cathode is usually made of carbon material. To increase the MFC efficiency it is necessary to search the new cathode materials. In this work, the electricity production from yeast wastewater in membrane-less microbial fuel cells with a carbon felt, Ni-Co, Cu-B, and Cu-Ag cathodes has been analyzed. In the first place, the measurements of the stationary potential of the electrodes (with Cu-Ag catalyst obtained by the electrochemical deposition technique) were performed. Next, the analysis of the electric energy production during the operation of the membrane-less microbial fuel cell (ML-MFC). The highest parameters were obtained for the Ni-Co and Cu-Ag catalysts. The cell voltage of 607 mV for Ni-Co and 605 mV for Cu-Ag was obtained. Additionally, the power of 4.29 mW for both cathodes - Ni-Co and Cu-Ag was obtained. Moreover, Ni-Co and Cu-Ag allow the shortest time of COD reduction. Based on the test results (with selected MFC design, wastewater, temperature, etc.), it can be concluded that of all the analyzed electrodes, Cu-Ag and Ni-Co electrodes have the best parameters for use as cathodes in ML-MFC. However, based on the results of this study, it can be concluded that all the tested electrodes can be used as cathode material in MFC.
