Bioelectrochemical systems: an outlook for practical applications.
Represents the amount of oxygen required to oxidize the biodegradable organic matter dissolved into the wastewater to CO 2 and H 2 O. MEC technology is an ideal candidate because it is able to recover part of this potential into hydrogen, thus helping to curb the energy requirements in the plant.
Prospects in bioelectrochemical technologies for wastewater treatment Simone Perazzoli Simone Perazzoli. Instead, their use as a pre-treatment step to extract the energy content of the organic matter is a more plausible option. Microbial electrolysis cells for high yield hydrogen bioelectrohemical production from organic matter.

Activated sludge AS systems, which have become a conventional wastewater treatment method in developed nations, usually make use of large blowers to favor oxygen transfer from air into the mixed liquor that are energy intensive and increase the treatment costs. Water Sci Technol 2 November ; 78 6: However, all of these methods are characterized by low systemms in terms of hydrogen yield Angenent et al.
More recent developments in bioelectrochemical systems BESs suggest that MECs may represent a promising technology for combining wastewater treatment and energy recovery Ditzig et al.
Close mobile search navigation Article navigation. A technological strategy to improve the process monitoring and control based on big data platforms is also presented.
Select your language of interest to view the total content in your interested language. This review addresses the factors that are essential for practical application of BESs.
These experiences have proved that MECs may become a feasible technology for dWW treatment, bringing competitive advantages over conventional aerobic treatments from energy usage and environmental points of view. Not all of the above mentioned restrictions and limitations have the same influence over MEC scalability, and some deserve special attention.
Evaluation of energy-conversion efficiencies in microbial fuel cells MFCs utilizing fermentable and non-fermentable substrates. The use of bioelectrochemical reactors MFC in particular for wastewater treatment was first proposed in by Habermann and Pommerand since then, several treatment process trains that integrate BESs in a WWTP have been envisioned Rosenbaum et al.
In situ microbial fuel cell-based biosensor for organic carbon. In contrast, a whole MEC reactor would need to be divided into a certain number of MEC units that would make up the whole treatment. Production of hydrogen from domestic wastewater using a bioelectrochemically assisted microbial reactor BEAMR.
Experimental determination of energy content of unknown organics in municipal wastewater streams. In both cases, the energy required to remove the organic contamination was below the energy consumption threshold typically associated with an aerobic treatment 1. Novel advanced porous concrete in constructed wetlands: Medical Records Systems, Computerized Search for additional papers on this topic. In the coming years may see a flurry of activity in this field as the research community tries to answer questions related to rates of electron supply to the microbes, determining practically feasible rates for producing fuel from carbon dioxide, managing bioelectrochemical losses related to scale-up of these systems, etc.
Among the several chemicals that may be extracted from wastewaters, hydrogen occupies a preeminent position because of its interesting characteristics as a fuel: Guidelines Upcoming Special Issues. If we assume that 1. Use of novel permeable membrane and air cathodes in acetate microbial fuel cells.
Bioelectrochemical systems: an outlook for practical applications.
Performance of a pilot-scale continuous flow microbial electrolysis cell fed winery wastewater. By using appropriate technologies, the potential practial energy contained in the organic compounds present bioelectrochemidal dWWs might help to improve the energy and economic balance of dWW treatment plants.
Although this is an issue that has not been fully studied, biomass production in the anode of a BES may lay in the range of 0. Further energy savings can be obtained from the reduced sludge production in MEC reactors.
Bioelectrochemical Systems, Energy Production and Electrosynthesis
If a BES is producing electrical energy, then the system is referred to as microbial fuel cell, whereas if it consumes electrical energy to drive the electrochemical reactions it is termed a MEC Rozendal et al.
