“…Thus, it is necessary to investigate the decolorization performance of azo dyes using biocathode BES. Furthermore, there are some studies on combination of anode and cathode in BES for wastewater or groundwater treatment (Li et al, 2010;Lohner et al, 2011;Sun et al, 2011a;Wen et al, 2010). Considering the bioanode decolorization at present, aircathode single chamber MFC has been used extensively (Cao et al, 2010;Hou et al, 2011bHou et al, , 2012Xu et al, 2013).…”

h i g h l i g h t sCR decolorization was accelerated with combined bioanode-biocathode BES. The biocathode played an important role in accelerating CR decolorization. Three electrodes deployments were compared based on startup, DE and EIS analysis. The surrounding mode was the best, followed by vertical and horizontal ones. The possible mechanism for the combined bioanode-biocathode was discussed. a r t i c l e i n f o In this study, BES with bioanode and biocathode was applied to decolorize an azo dye Congo red (CR). Results showed that the Congo red decolorization efficiency (CR-DE) within 23 h in a combined bioanode-biocathode single chamber BES was 98.3 ± 1.3%, significantly higher than that of mixed solution in a dual chamber BES (67.2 ± 3.5%) (P < 0.005). Various electrodes deployments (horizontal, vertical and surrounding) in the combined bioanode-biocathode BES were further compared based on the decolorization performance and electrochemical characterization. Results indicated that CR-DE within 11 h improved from 87.4 ± 1.3% to 97.5 ± 2.3%, meanwhile the internal resistance decreased from 236.6 to 42.2 X as modifying the horizontal deployment to be a surrounding deployment. It proved that the combination of bioanode and biocathode with suitable electrodes deployment could accelerate the decolorization of azo dye Congo red, which would be great potential for the application of bioelectrochemical technology in azo dye wastewater treatment.

“…Fuel compounds are also regarded as a major determinant of MFC performance. Pure compounds such as glucose, acetic acid, and lactic acid have been used successfully, while mixed substrates such as brewery waste water [10,11], swine wastewater [12], distillery wastewater [13], and landfill leachate [14] have been used to demonstrate MFC as a novel technology that couples renewable energy production with wastewater treatment.…”

The power generation potential of a microbial fuel cell (MFC) during the process of benzene biodegradation with potassium ferricyanide (0–200 mM) as the terminal electron acceptor was evaluated. Experimental results demonstrate that benzene was used as the sole carbon source in generating electricity by a mixed culture. The power density increased from 0.0276 to 2.1 mW m−2 as the concentration of potassium ferricyanide in the cathode chamber was increased from 0 to 200 mM. With a benzene concentration of 10.87 mg L−1 and a potassium ferricyanide concentration of between 0 and 150 mM, complete degradation of benzene was achieved in 22–24.5 h. However, when the concentration of potassium ferricyanide was raised to 200 mM, the time required for complete benzene degradation was prolonged to 35 h. The results of this investigation can be used as a basis for future assessments of the power generation capacity of MFCs that are used to treat benzene‐contaminated wastewater.

“…Marsili-libelli et al [9] have used the least squares technique to estimate oxygen transfer coefficient and OUR in real time according to the dynamic characteristics of the air flow and dissolved oxygen. Controlling DOC in the processes of wastewater treatment is, however, still an operational challenge [10]. A key question for this is what the primary factors that influence the DOC are.…”

ABSTRACT:The dissolved oxygen concentration (DOC) in water is an important indicator of self-purification capacity of water in wastewater treatment system. In this study, the operating processes of wastewater treatment systems are modeled based on the mechanism model. Meanwhile, different factors that influence the DOC are analyzed. The adaptive dynamic model of DOC is established in the Matlab environment considering white noise in the model input. The effect of the input variables (e.g., aeration tank) and load variables (e.g., oxygen consumption) on the DOC is analyzed in detail when white noise is considered in the model input. The transform transient characteristics of DOC are obtained after leaving out outliers of the input variables. As an on-line outlier's detection method, abnormal value detection is used to remove the inferior quality data in order to ensure the reliability of the efficiency of the developed model. Results demonstrate that the adaptive dynamic simulation model can be used to improve both the accuracy of modeling and the ability of modeling system dynamics.
