BACKGROUND Developing an economical biological nitrogen and phosphorus removal technology with high efficiency has become a research priority in current sewage treatment procedures. In order to solve the problems within the anaerobic–anoxic–oxic (A2/O) process, including substrates competition and high energy consumption, a microbial fuel cell (MFC) was embedded in the A2/O process to enhance the efficiencies of removal of nitrogen and phosphorus, along with electricity production. RESULTS Three A2/O reactors, one with an embedded MFC, were set up, and nitrogen and phosphorus removal efficiencies and electricity generation were investigated. At the stage of stable operation, the chemical oxygen demand, total nitrogen and total phosphorus removal efficiencies of the MFC‐A2/O reactor, compared with the control, were increased by 15.9%, 9.3% and 1.4% on average, respectively. The average output power density of the MFC was 14.3 ± 1.4 mW m−3 and the internal resistance was 6000 Ω. Grey relational analysis was applied to study the most significant operational parameter of the A2/O process affecting electricity production of the MFC. CONCLUSIONS This research proved that nitrogen and phosphorus removal efficiency could be improved by embedding an MFC in the A2/O process. In addition, the MFC‐A2/O reactor can generate electricity continuously. © 2013 Society of Chemical Industry

“…Those processes are significantly influenced by changes in temperature, and so they affect the performance of the MFC for energy generation [60][61][62][63]. On the other hand, the influence of the temperature will change depending on the specific nature of the microorganism and the feedstock employed [58,[62][63][64][65][66][67][68][69][70][71][72][73][74][75].…”

“…Therefore, different optimum temperatures will be required depending on the specific characteristics of the MFC. Various investigations have proved a significant enhancement of the power output by increasing the reaction temperature in the anode chamber [58,62,[64][65][66][67][68][69][70][71][72][73]. That improvement in the power density has been related to an enhancement of the microbial metabolism and membrane permeability, as well as to the reduction of ohmic resistance due to a higher conductivity of the liquid solution by increasing the temperature [62,63].…”

“…It is worth mentioning that biofilm formation can be also be affected by temperature changes [58,62,[64][65][66][67][68][69][70][71][72][73][74][75], since biofilm development at the anode has an important impact on the anodic biocatalytic activity, and therefore on the energy generation. In that way, some studies show that the initial temperature is crucial in the formation of the biofilm in a MFC, and consequently, in the time needed for the startup.…”

“…Regardless of the aforementioned, some microorganisms naturally prefer low-temperature environments to reach optimum performance, which is potentially useful for MFC-driven sensors to be placed in cold areas [62,63]. However, at extremely low temperatures, microbial reactions slow down and eventually MFCs cannot operate.…”

A microbial fuel cell (MFC) is a type of bio-electrochemical system with novel features, such as electricity generation, wastewater treatment, and biosensor applications. In recent years, progressive trends in MFC research on its chemical, electrochemical, and microbiological aspects has resulted in its noticeable applications in the field of sensing. This review was consequently aimed to provide an overview of the most interesting new applications of MFCs in sensors, such as providing the required electrical current and power for remote sensors (energy supply device for sensors) and detection of pollutants, biochemical oxygen demand (BOD), and specific DNA strands by MFCs without an external analytical device (self-powered biosensors). Moreover, in this review, procedures of MFC operation as a power supply for pH, temperature, and organic loading rate (OLR) sensors, and also self-powered biosensors of toxicity, pollutants, and BOD have been discussed.
