AbstractIn the present world scenario the demand for fresh water and clean energy is driving the need to convert a microbial fuel cell (MFC) into an algal-based microbial desalination cell (MDC) that can support algal growth along with desalination of saline water. In this study, the performance of a five-chambered MDC fed with saline water having two different salt concentrations, namely 2.5 g/L and 5.0 g/L in desalination chamber, as well as MDC operated without algae in catholyte was investigated. The algal-based MDC operated with 5 g/L of total dissolved solid (TDS) in desalination chamber exhibited the best performance results among all other combinations giving a maximum power density of 45.52 mW/m2 and a desalination efficiency of 71 ± 2 %. Also, a chemical oxygen demand (COD) removal efficiency of 78 % and coulombic efficiency of 12.24 % was achieved with 5 g/L NaCl concentration in desalination chamber. Based on this experimental performance evaluation, it can be inferred that algal-based MDC can provide a promising and sustainable approach for wastewater treatment with the capability of simultaneous desalination, algal production and electrical energy recovery.

Pandanus Amaryllifolius

Plant microbial fuel cell (P-MFC) is an electrochemical reactor that converts organic compounds to electrical energy through the catalytic reaction from electrochemically active bacteria (EAB). However, there is no sign of an attempt in developing the functional model in predicting the energy conversion and utilization of P-MFC. In this study, an analytic model is proposed to show the whole production process of the organic compound to electrical energy generation. <em>Pandanus Amaryllifolius</em> plant was used as sources of photosynthate, where biomass product from rhizodeposition, acetate was produced, and soil bacteria as the microbial culture, and air as the input to the cathode chamber. The proposed analytical model is able to predict the output of the P-MFC using the parameters from the experiment. The generated data from the model was then compared with the monitored data from the <em>Pandanus Amaryllifolius </em>P-MFC. The results show the electrical power output has a high similarity pattern with the bacterial growth curve model and able to achieve the coulombic efficiency of 95.32%.

Finding sustainable alternative energy resources and treating wastewater are the two most important issues that need to be solved. Microbial fuel cell (MFC) technology has demonstrated a tremendous potential in bioelectricity generation with wastewater treatment. Since wastewater can be used as a source of electrolyte for the MFC, the salient point of this study was to investigate the effect of pH on bioelectricity production using various biomass feed (wastewater and river water) as the anolyte in a dual-chambered MFC. Maximum extents of power density (1459.02 mW·m−2), current density (1288.9 mA·m−2), and voltage (1132 mV) were obtained at pH 8 by using Bhairab river water as a feedstock in the MFC. A substantial extent of chemical oxygen demand (COD) removal (94%) as well as coulombic efficiency (41.7%) was also achieved in the same chamber at pH 8. The overall performance of the MFC, in terms of bioelectricity generation, COD removal, and coulombic efficiency, indicates a plausible utilization of the MFC for wastewater treatment as well as bioelectricity production.

Abstract Production of bioethanol and bioelectricity is a promising approach through microbial electrochemical technology. Sugars are metabolized by yeast to produces ethanol, CO2 and energy. Surplus electrons produced during the fermentation can be transferred through the circuit to generate electricity in a Microbial fuel cell (MFC). In the present study, a membrane less single chambered microbial fuel cell was developed for simultaneous production of bioethanol and bioelectricity. Pichia fermentans along with a well-known ethanol producing yeast Saccharomyces cerevisiae was allowed to ferment glucose. S. cerevisiae demonstrated maximum open circuit voltage (OCV) 0.287 ± 0.009 V and power density 4.473 mW m− 2 on 15th day, with a maximum ethanol yield of 5.6% (v/v) on 12th day. P. fermentans demonstrated a maximum OCV of 0.318 ± 0.0039 V and power density of 8.299 mW m− 2 on 15th day with ethanol yield of 4.7 % (v/v) on 12th day. Coulombic efficiency (CE) increased gradually from 0.002–0.471 % and 0.012–0.089 % in the case of S. cerevisiae and P. fermentans, respectively, during 15 days of experiment. Thus, the result indicated that Single chambered fuel cell can be explored for its potential applications for ethanol production along with clean energy generation.

Abstract The effects of mixed feeding of boiled potato and waste activated sludge (WAS) on the performance of a microbial fuel cell (MFC) in treating solid potato waste were investigated. The coulombic efficiency (CE) of four MFCs fed with potato cubes containing 0, 48.7, 67.3 and 85.6% of boiled potato was 53.5, 70.5, 92.7 and 71.1%, respectively, indicating enhanced electricity generation and the existence of an optimum mixing ratio. The hydrolysis rate estimated using a first-order sequential hydrolysis model increased from 0.061 to 0.191 day−1, leading to shortening of the startup time for current density reaching its maximum from 25 to 5 days. The final chemical oxygen demand (COD) removal reached 85%. The CE of seven MFCs, fed with raw potato alone, sterilized/unsterilized WAS alone, and four mixed samples of raw potato with sterilized WAS at ratios of 2:1 and 4:1 and unsterilized WAS at 2:1 and 4:1, was found to be 6.1, 43.6, 0.3, 31.0, 16.5, 0.9 and 31.1%, respectively. The hydrolysis rate increased from 0.056 to 0.089 day−1, and the final COD removal changed from 39.5 to 89.6% following the order: potato alone &gt; mixture of potato & WAS &gt; sterilized WAS alone &gt; unsterilized WAS alone.

Palm oil mill effluent (POME) discharged without treatment into watercourses can pollute the water source. Microbial fuel cell (MFC) has gained high attention as a green technology of converting organic wastewater into bio-energy. As an approach to overcome the limitations of the existing POME treatment methods, air-cathode MFC-Adsorption system is introduced as an innovative technology to treat POME and generate bio-electricity simultaneously. However, the use of conventional MFC with proton exchange membrane in large scale applications is restricted by the high cost and low power generation. Addition of mediator in MFC is essential in order to increase the electron transfer efficiency, hence enhancing the system performance. This study therefore aims to investigate the effect of different type of mediators i.e. congo red (CR), crystal violet (CV) and methylene blue (MB) on the performance of an affordable air-cathode MFC-Adsorption system made from earthen pot with POME as the substrate. The addition of different mediators altered the pH of the MFC-Adsorption system, in which more alkaline system showed better performance. The voltage generated in the system with CR, CV and MB mediator was 120.58 mV, 168.63 mV and 189.25 mV whereas the current generated was 2.41 mA, 3.37 mA and 3.79 mA, respectively. The power density of 290.79 mW/m3, 568.72 mW/m3 and 716.31 mW/m3 was produced in the MFC-Adsorption system with CR, CV and MB mediator, respectively. The highest POME treatment efficiency was achieved in MFC-Adsorption system with MB mediator, which resulted in biochemical oxygen demand, chemical oxygen demand, total suspended solids, turbidity and ammoniacal nitrogen removal of 75.3%, 84.8%, 91.5%, 86.1% and 23.31%, respectively. Overall, the air-cathode MFC-Adsorption system with addition of MB mediator was feasible for POME treatment and simultaneous bio-energy generation.

Power management systems (PMSs) are essential for the practical use of microbial fuel cell (MFC) technology, as they replace the unstable stacking of MFCs with step-up voltage conversion. Maximum-power extraction technology could improve the power output of MFCs; however, owing to the power consumption of the PMS operation, the maximum-power extraction point cannot deliver maximum power to the application load. This study proposes a practical power extraction for single MFCs, which reserves more electrical energy for an application load than conventional maximum power-point tracking (MPPT). When experimentally validated on a real MFC, the proposed method delivered higher output power during a longer PMS operation time than MPPT. The maximum power delivery enables more effective power conditioning of various micro-energy harvesting systems.
