Bioelectrochemical systems (BESs) have the potential to produce energy from wastewater. However, they are far from ready to be applied into industry. The development of large and pilot-scale systems to harness energy and value-added chemicals is widely regarded as one of the greatest research challenges in this field. There are several reasons for this: i) they are expensive, ii) they are difficult to engineer, iii) the data that can be derived from them is often limited, rarely in duplicate, and is disproportionate to the time commitment. Given these restrictions, systematic reviews of large and pilot-scale systems can be helpful in determining the direction of future research. These reviews need to standardise very different reactor set-ups, operational conditions, and methods of reporting data. Here we present an analysis of the energy production from semi-pilot and pilot-scale BESs, and benchmark their performance against existing wastewater treatment. The parameters used include complexity of wastewater; chemical oxygen demand (COD) loading rate; conductivity; reactor depth; volumetric treatment rate; effluent quality; energetic treatment balance; and temperature. We find that factors which are perceived to be problematic, such as low conductivities and temperatures, have been overcome by BESs at pilot-scale, and that these systems have met the regulatory requirements for discharge standards. We identify reactor depth and volumetric treatment rate as the areas for future research to focus on. The first of these issues will need an engineering solution, while the second is likely to come from improved understanding of the complex microbial digestion pathways. Material science may help both. Importantly, these pilot studies have shown that renewable energy production from wastewater is possible, and with targeted future research, could become a reality.

This review emphasizes the applicability of bioelectrochemical systems for the treatment of wastewaters contaminated with xenobiotic compounds. Treatment options for dyes, antibiotics, aromatics and chlorinated compounds are reviewed in this article. Two major variants of bioelectrochemical systems, namely microbial fuel cell (MFC) and microbial electrolysis cell (MEC), are discussed in light of xenobiotics removal. The efficiency of each system in terms of pollutant removal and power recovered/utilised is discussed and degradation mechanisms for these biorefractory compounds are described. This review also discusses the removal and recovery of heavy metals through biocatalytic and electrochemical reduction in the cathodic chamber of MFC and MEC. Further, the future scope of research is also elaborated in light of different issues pertaining to the replicability and scalability of the system.

Advancements in biological wastewater treatment with sustainable and circularity approaches have a wide scope of application. Biological wastewater treatment is widely used to remove/recover organic pollutants and nutrients from a diverse wastewater spectrum. However, conventional biological processes face challenges, such as low efficiency, high energy consumption, and the generation of excess sludge. To overcome these limitations, integrated strategies that combine biological treatment with other physical, chemical, or biological methods have been developed and applied in recent years. This review emphasizes the recent advances in integrated strategies for biological wastewater treatment, focusing on their mechanisms, benefits, challenges, and prospects. The review also discusses the potential applications of integrated strategies for diverse wastewater treatment towards green energy and resource recovery, along with low-carbon fuel production. Biological treatment methods, viz., bioremediation, electro-coagulation, electro-flocculation, electro-Fenton, advanced oxidation, electro-oxidation, bioelectrochemical systems, and photo-remediation, are summarized with respect to non-genetically modified metabolic reactions. Different conducting materials (CMs) play a significant role in mass/charge transfer metabolic processes and aid in enhancing fermentation rates. Carbon, metal, and nano-based CMs hybridization in different processes provide favorable conditions to the fermentative biocatalyst and trigger their activity towards overcoming the limitations of the conventional process. The emerging field of nanotechnology provides novel additional opportunities to surmount the constraints of conventional process for enhanced waste remediation and resource valorization. Holistically, integrated strategies are promising alternatives for improving the efficiency and effectiveness of biological wastewater treatment while also contributing to the circular economy and environmental protection.

A novel framework, integrating dynamic simulation (DS), life cycle assessment (LCA) and techno-economic assessment (TEA) of a bioelectrochemical system (BES), has been developed to study for the first time wastewater treatment by removal of chemical oxygen demand (COD) by oxidation in anode and thereby harvesting electron and proton for carbon dioxide reduction reaction or reuse to produce products in cathode. Increases in initial COD and applied potential increase COD removal and production (in this case formic acid) rates. DS correlations are used in LCA and TEA for holistic performance analyses. The cost of production of HCOOH is €0.015-0.005 g -1 for its production rate of 0.094-0.26 kg yr -1 and a COD removal rate of 0.038-0.106 kg yr -1 . The life cycle (LC) benefits by avoiding fossil-based formic acid production (93%) and electricity for wastewater treatment (12%) outweigh LC costs of operation and assemblage of BES (-5%), giving a net 61MJkg -1 HCOOH saving.

Abstract BACKGROUND This work develops a simplified mathematical model to predict the performance of a bioelectrochemical system (BES), first working as a microbial fuel cell (MFC) and then as a microbial electrolysis cell (MEC), for the recovery of dissolved metals (Fe, Cu, Sn, and Ni) from simulated industrial wastewater. Experimental data from a previous work were used as starting points for mathematical modelling. Wastewater was used as the catholyte and contained Cu 2+ and Fe 3+ (500 mg L −1 ) as well as Sn 2+ and Ni 2+ (50 mg L −1 ), while the anolyte was composed of sodium acetate. Two mixed microbial populations were considered in the anode compartment (electrogenic and non‐electrogenic biomass). Dissolved metal ions were the electron acceptors in the electrogenic mechanism: Cu 2+ and Fe 3+ under MFC mode and then Fe 2+ , Ni 2+ , and Sn 2+ under MEC mode. RESULTS The model predicted the organic substrate and microbial biomass (anode chamber) and Fe 3+ and Cu 2+ (cathode chamber) concentrations during MFC operation. Monod kinetic and stoichiometric parameters were calibrated, and it was observed that most of the organic substrate underwent a non‐electrogenic mechanism. The generation of electric current until electron acceptors were removed was also predicted. Concentration profiles and first‐rate constant values for the decreased Sn 2+ , Ni 2+ , and Fe 2+ concentrations during the subsequent MEC operation were also obtained. The model was then used for simulations under different experimental conditions. CONCLUSION This work offers a single grey‐box model proposal that is easy to implement, and it can be used as a practical tool for testing the removal of dissolved metals in BESs. © 2021 Society of Chemical Industry (SCI).

The performance of upflow anaerobic bioelectrochemical reactor (UABE), equipped with electrodes (anode and cathode) inside the upflow anaerobic reactor, was compared to that of upflow anaerobic sludge blanket (UASB) reactor for the treatment of acidic distillery wastewater. The UASB was stable in pH, alkalinity and VFAs until the organic loading rate (OLR) of 4.0 g COD/L.d, but it became unstable over 4.0 g COD/L.d. As a response to the abrupt doubling in OLR, the perturbation in the state variables for the UABE was smaller, compared to the UASB, and quickly recovered. The UABE stability was better than the UASB at higher OLR of 4.0-8.0 g COD/L.d, and the UABE showed better performance in specific methane production rate (2,076 mL CH4/L.d), methane content in biogas (66.8%), and COD removal efficiency (82.3%) at 8.0 g COD/L.d than the UASB. The maximum methane yield in UABE was about 407 mL/g CODr at 4.0 g COD/L.d, which was considerably higher than about 282 mL/g CODr in UASB. The rate limiting step for the bioelectrochemical reaction in UABE was the oxidation of organic matter on the anode surface, and the electrode reactions were considerably affected by the pH at 8.0 g COD/L.d of high OLR. The maximum energy efficiency of UABE was 99.5%, at 4.0 g COD/L.d of OLR. The UABE can be an advanced high rate anaerobic process for the treatment of acidic distillery wastewater.
