“…MFCs are new bioelectrochemical systems in which a microorganism catalyzes and oxidizes the organic compounds and converts the chemical energy stored by the organic matter into electrical energy. − Sediment microbial fuel cells (SMFCs) are special battery systems evolved from the traditional MFC structure. The anode is buried in the anaerobic bottom sludge, and the microorganisms in the bottom sludge are used as catalysts to degrade organic matter into CO 2 and H 2 O and generate electrons.…”

The anode is considered to be a key factor to improve the single-chamber bioelectrochemical system’s efficiency to degrade oily sludge in sediment while generating electricity. There are few studies on the effect of the anode structure on the performance of oily sludge MFCs systematically. In this paper, an oily sludge bioelectrical system was constructed using carbon felt and carbon plate as anode materials, adjusting the anode material arrangement as transverse and longitudinal, and using different anode materials from single to sextuple anodes. The results of this study showed that the rate of degradation of oily sludge was greater with carbon felt (17.04%) than with the carbon plate (13.11%), with transverse (23.61%) than with the longitudinal (19.82%) arrangement of anodes, and with sextuple anodes (33.72%) than with a single anode (25.26%) in the sediment microbial fuel cells (SMFCs). A similar trend was observed when the voltage, power density, and electromotive force (EMF) of SMFCs were estimated between the carbon felt and carbon plate, transverse and longitudinal arrangements, single and sextuple anodes. It is concluded that the proper adjustment of anode arrangements, using carbon felt as an anode material, and increasing the number of anodes to six may accelerate the rate of degradation of oily sludge in oily sludge sediment microbial fuel cells (SMFCs). Furthermore, the electricity generation performance was also improved.

“…21 The optimal conditions for MFC operation were obtained using the microbial cultures isolated from freshwater sediments, such as the sediment from Danube River in Serbia and the sediment from Lake Uzungeren in Bulgaria. 22,23 Based on the recent development in the field and taking into account the situation in the region of Bor, Serbia this paper aimed to investigate the eventual application of MFC as an approach to manage the wastewater streams generated by the local metallurgical industry and community. The performance of a labscale reactor towards Cu ions and COD removal was tested using a model and real wastewater samples.…”

Microbial fuel cell (MFC) is a hybrid technology that produces electricity and recovers resources from wastewater through biocatalytic and electrochemical reactions. Metallurgical facilities in Bor, Serbia, are a source of copper-rich metallurgical wastewater, and the Town of Bor is a source of municipal wastewater rich in organic matter. The aim of this paper is to investigate the possibility of application of MFC for the treatment of metallurgical and municipal wastewater that are released into the Bor River in Serbia. A prototype of MFC was constructed for this study, and 3 sets of experiments were performed using model solutions and real wastewater. Copper was successfully removed from the treated model solution with 99.42 % efficiency. Solid copper particles were obtained with a particle size of about 1 ?m. Maxi-mum chemical oxygen demand (COD) removal rate of 191.7 mg L-1 h-1 was observed in the anodic compartment. The impact of this study is significant because MFC was implemented for the simultaneous treatment of two types of wastewaters, one containing metals and the other containing organic matter, and both types of wastewater are released into the same river.
