This article describes a proof-of-concept study designed for the reuse of wastewater using microbial electrochemical cells (MECs) combined with complementary post-treatment technologies. This study mainly focused on how the integrated approach works effectively for wastewater reuse. In this study, microalgae and ultraviolet C (UVC) light were used for advanced wastewater treatment to achieve site-specific treatment goals such as agricultural reuse and aquifer recharge. The bio-electrosynthesis of H 2 O 2 in MECs was carried out based on a novel concept to integrate with UVC, especially for roust removal of trace organic compounds (TOrCs) resistant to biodegradation, and the algal treatment was configured for nutrient removal from MEC effluent. UVC irradiation has also proven to be an effective disinfectant for bacteria, protozoa, and viruses in water. The average energy consumption rate for MECs fed acetate-based synthetic wastewater was 0.28±0.01 kWh per kg of H 2 O 2 , which was significantly more efficient than are conventional electrochemical processes. MECs achieved 89±2% removal of carbonaceous organic matter (measured as chemical oxygen demand) in the wastewater (anolyte) and concurrent production of H 2 O 2 up to 222±11 mg L -1 in the tapwater (catholyte). The nutrients (N and P) remaining after MECs were successfully removed by subsequent phycoremediation with microalgae when aerated (5% CO 2 , v/v) in the light. This complied with discharge permits that limit N to 20 mg L -1 and P to 0.5 mg L -1 in the effluent. H 2 O 2 produced on site was used to mediate photolytic oxidation with UVC light for degradation of recalcitrant TOrCs in the algal-treated wastewater. Carbamazepine was used as a model compound and was almost completely removed with an added 10 mg L -1 of H 2 O 2 at a UVC dose of 1000 mJ cm -2 . These results should not be generalized, but critically discussed, because of the limitations of using synthetic wastewater.

Waste pollution contributes to environmental problems, including soil erosion, health problems, and biodiversity loss. A shortage of waste disposal sites and the unexpected generation of millions of tons of solid waste worldwide led to the adoption of various thermal, physical, and biological technologies to convert waste into energy. Through several systematic endeavours in recent years, wastewater management have been effectively achieved upon adoption of sustainable waste management pipelines, bioelectrochemical system for bioenergy production, and usage of nanoparticles guided remediation procedures. Bioelectrochemical systems are emerging techniques for waste management that utilize microbial electron transfer and electrochemical transformation to generate sustainable and carbon-neutral energy. Recent technological advancement has allowed microbial communities to play an increasingly important role in bioelectrochemical systems. Microbiological electrochemical systems (MESs) have emerged as sustainable technology for generating renewable energy and valuable products from waste. Further, different nanotechnological approaches are also being frequently used to generate energy and wastewater pollutants due to their broad spectrum activity, enhanced specificity and selectivity. Their reported antimicrobial nature against several nosocomial and pathogenic microbes dwelling in wastewater has been an added boon for environmentalists prompting their regular usage. This review article integrates recent and updated bioelectrochemical approaches for generating energy and wastewater remediation mechanisms and strategies alongside their various challenges and opportunities.

Application of the plant microbial fuel cell (PMFC) in wetlands should be invisible without excavation of the soil. The preferred design is a tubular design with the anode directly between the plant roots and an oxygen reducing biocathode inside the tube. Oxygen should be passively supplied to the cathode via a gas diffusion layer. In this research silicone was successfully used as gas diffusion layer. The objective of this research is to start-up an oxygen reducing biocathode in situ in a tubular PMFC applied in a Phragmites australis peat soil and a Spartina anglica salt marsh. PMFCs with a biocathode were successfully started in the peat soil. Oxygen reduction is clearly catalysed, likely by microorganisms in the cathodes, as the overpotential decreased resulting in an increased current density and cathode potential. The maximum daily average power generation of the best peat soil PMFC was 22 mW m−2. PMFCs with a biocathode in the salt marsh only started with pure oxygen diffusion reaching a maximum daily average power generation of 82 mW m−2. Both wetland PMFCs were successfully started with natural occurring microorganism in the anode and cathode. Calculations show that the power density can be increased by improving the PMFC design limiting crossover of oxygen and substrate.

Sludge dewatered filtrates could generate unpredicted stress to the biological treatment process of wastewater treatment plants (WWTPs) due to the applied chemical compounds. Here, sludge dewatering performances with different conditioners were evaluated and the stress of the dewatered filtrate to the microbial was detected by microbial fuel cells (MFCs). Dewatered filtrates from Fe2+/H2O2 and Fe2+/Ca(ClO)2 conditioning were recommended, and the voltage inhibition ratios were only 24.28% and 31.58% as the MFC substrate was 100% filtrate. However, the voltage inhibition ratios were up to 70.33% and 90.33% as MFC substrates were 50% filtrate from Fe2+/PDS and Fe3+/CaO conditioning. High pH (>12) of filtrate from Fe3+/CaO conditioning and the remaining oxidation reagent in the filtrate from Fe2+/PDS conditioning significantly increased damaged cell ratios at anodic biofilms from 9.8% to 24.6% and 26.1%, indicating negative impacts on microbial activity. This study provided a reference for the impact of dewatered filtrate returned to the influence of WWTPs.

Progress towards green and autonomous energy sources includes exploiting living systems and biological tissue for harvesting electrical energy. Plant-microbial fuel cells (P-MFCs) have recently been identified as a promising energy source for continuously and indefinitely supplying autonomous electronic devices, such as, for example, sensor nodes. This paper reports the results of the characterization of microbial fuel cells supplied by pot plants in terms of harvestable electrical energy. The results show that electronic devices with a power consumption lower than 1mW can be easily operated continuously with the energy produced by P-MFCs. As test cases, P-MFCs have been used to power LEDs as well as a temperature and relative humidity sensor.
