Hence, the operating costs of treating wastewater are bound to increase despite the fact that a significant amount of the energy investment can be recovered as biogas from anaerobic digesters. However, it has been argued that fostering methane production using biocathodes containing methanogens rather than avoiding it, could bring additional advantages over hydrogen Cheng et al.

The implementation of this emerging technology at the commercial scale would be driven by reliability and costs, and it is expected that the first generation of MECs could be ready within 1—4 years European Commission, November 29, Citation: November 26, ; Published Date: Biological fuel cells with sulphide storage capacity.

The field includes the specific area of electrofuels, which is production of transportation fuels starting from carbon dioxide [ 8 ] and production of chemicals such as hydrogen peroxide [ 9 ], caustic [ 10 ], 1,2-propanediol, etc. Therefore, wastewater acidification prior to the BES treatment Figure 2 D would likely increase its performance, degrading high-molecular-weight organics into relatively simple VFAs, which are readily converted to electricity in a BES Li and Yu,even at low concentrations Lee et al.

The study concludes with a discussion of the future perspectives of MEC technology for dWW treatment.

There is also a need to build a bridge between the existing routes of biocatalytic pathways for chemical production to reagents and reducing equivalents that enter the cells from extracellular environment via biologically mediated electroactive structures. D The BES is preceded by an acidification step two-stage process and followed by a polishing step. Select your language of interest to view the total content in your interested language.

If a BES is producing electrical energy, vor 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. Energy Recovery from Organic Matter Contaminated Streams A BES bioelectrocbemical be defined as an electrochemical system in which at least one of the anodic or cathodic appliations is microbially catalyzed Rabaey et al.

Two-phase anaerobic co-digestion of olive mill wastes in semi-continuous digesters at mesophilic temperature. 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.

First, we compare benefits value of products and cleaning of wastewater with costs capital and operational costs. In addition, the removal of nitrogen an important contaminant in dWW in a MFC—MEC is usually low, and it is mostly attributable to nitrogen assimilation into bacterial biomass, which accounts for only a small percent of the total removal usually needed Freguia et al.


Wastewaters are polluted with many materials and substances, the most common being: Hydrogen production from glycerol in a membraneless microbial electrolysis cell.

Current research is focused on synthetic biology to integrate pathways for carbon dioxide assimilation into biochemical building blocks such as acetyl CoA, assembly of biological circuits with redox enzymes to transport electrons from hydrogen, electricity or reduced chemicals to NADH appoications ATP production.

Consequently, and to improve the economic and energy balances in MECs and as a result, their applicabilityfurther enhancements would be required in areas such as: Despite the loss of bioelextrochemical the energy recovery was not enough to offset the energy inputthe overall energy usage to remove the organic pollution was again below that of aerobic treatments.

Electrosynthesis has emerged as a new field of research in the last two years where electrical current is used for synthesis of fuels fkr chemicals. Figure 1 shows a schematic representation of the operation of BESs. Towards practical implementation of bioelectrochemical wastewater treatment.

The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Whereas in MFCs the presence of an oxidative agent usually oxygen causes the electrical current to flow spontaneously, MECs require a certain amount of electrical input to drive the redox reactions because no oxygen or oxidative agent is allowed to enter the cathode chamber.

It begins with a brief account of the basics of BESs, followed by an examination of how MECs can be integrated in dWWTPs, identifying scaling-up bottlenecks and estimating potential energy savings.
