“…A power density of 152.70 mW m −3 was obtained using the Nafion® 117 membrane in a similar tubular reactor in stack design for septic tanks. This value was 24.22% smaller than that obtained in the present study with the same membrane and greywater cathode design . The difference is a consequence of Alzate et al .…”

“…It has been reported that when using acetate as a substrate, 10% more COD removal can be obtained than when domestic wastewater is used . Using the Nafion® 117 membrane, an 89.67% COD removal was obtained in a nine‐cell stack with a design similar to the reactor used in this study .

“…This value was 24.22% smaller than that obtained in the present study with the same membrane and greywater cathode design. 30 The difference is a consequence of Alzate et al using glucose, a more complex substrate than the acetate used in this study. It has been reported that glucose favours fermentative processes, competing for electrons with electrogenic bacteria, producing a decrease ≤37 times the power generation.…”

BACKGROUND Greywater and blackwater treatment is necessary to make sanitation and water reuse possible, and microbial fuel cells (MFCs) have emerged as a promising technology for achieving this objective. Ion exchange membranes play a key role in double chamber microbial fuel cell performance, but there are differences of opinion as to which membrane type is better. RESULTS This project was set up to study the effect of three ion exchange membranes (Nafion® 117, Ultrex™ CMI‐7000 and Ultrex™ AMI‐7001) in MFCs using greywater as catholyte in stacks of three microbial fuel cells each. The results demonstrate that the stacks with cationic membranes (Nafion® 117 and Ultrex™ CMI‐7000) generated higher power (201.50 ± 21.62 and 178.74 ± 56.89 mW m−3, respectively) than those with the anionic membrane stack Ultrex™ AMI‐7001 (71.57 ± 3.46 mW m−3). For the greywater catholyte, a 31% of chemical oxygen demand removal was achieved and proved to be an option as a catholyte in microbial fuel cells for countries that carry out wastewater separation. CONCLUSIONS The results obtained in this study demonstrated that an anion exchange membrane is not a better option for double chamber MFCs. © 2019 Society of Chemical Industry

“…Rivers, ground water, lakes and other sources of fresh water must be taken care of (i.e., avoid illegal wastewater discharges) to prevent a lack of availability and to protect the ecosystem. Microbial fuel cells (MFC) are an emerging technology that can be used to treat wastewater because they function as bioreactors where bacteria become electrocatalysts that convert residual biomass found in wastewater into bioenergy [2].…”

The most important operational expense during wastewater treatment is electricity for pumping and aeration. Therefore, this work evaluated operational parameters and contaminant removal efficiency of a microbial fuel cell stack system (MFCSS) that uses no electricity. This system consists of (i) septic tank primary treatment, (ii) chamber for secondary treatment containing 18 MFCs, coupled to an energy-harvesting circuit (EHC) that stores the electrons produced by anaerobic respiration, and (iii) gravity-driven disinfection (sodium hypochlorite 5%). The MFCSS operated during 60 days (after stabilization period) and it was gravity-fed with real domestic wastewater from a house (5 inhabitants). The flow rate was 600 ± 100 L·d −1 . The chemical oxygen demand, biological oxygen demand, total nitrogen and total phosphorous were measured in effluent, with values of 100 ± 10; 12 ± 2; 9.6 ± 0.5 and 4 ± 0.2 mg·L −1 , and removal values of 86%, 87%, 84% and 64%, respectively. Likewise, an EHC (ultra-low energy consumption) was built with 6.3 V UCC ® 4700 µF capacitors that harvested and stored energy from MFCs in parallel. Energy management was programmed on a microcontroller Atmega 328PB ® . The water quality of the treated effluent complied with the maximum levels set by the Mexican Official Standard NOM-001-SEMARNAT-1996-C. A cost analysis showed that MFCSS could be competitive as a sustainable and energy-efficient technology for real domestic wastewater treatment.
