“…The reactor setups for both studies were done on standalone MFC and recently, only one had come to the effort of integrating MFC with adsorption hybrid system with ceramic pot as the PEM [32]. Besides, the effects of temperature in MFC hybrid system has never been understood especially when activated carbon is applied in the design because the performance of both MFC and adsorption system are sensitive to operating temperatures.…”

“…A recent study has been done by integrating MFC with adsorption system and such system has demonstrated great pollutants removal in the palm oil mill effluent (POME) such as COD, biochemical oxygen demand (BOD), total organic carbon (TOC), TN, NH 3 À ÀN, total solids (TS), total suspended solids (TSS), total volatile solids (TVS), turbidity and color [32]. Till now, the study of such system was only done at operating temperature of 25 AE 1 C. The effect of other operating temperature for such system has not been studied in terms of wastewater treatment and bio-energy generation.…”

A B S T R A C TA cost effective single-chamber microbial fuel cell (MFC) integrated with adsorption system was tested under different operating temperatures to observe pH profiles, organics, solids, nutrients, color and turbidity removal and power density generation. The optimum operating temperature range was found to be $25-35 C with majority of the removals achieved at $35 C. Maximum power density recorded was 74 AE 6 mW/m 3 with coulombic efficiency (CE) of 10.65 AE 0.5% when operated at 35 C. Present studies had successfully demonstrated the effectiveness of a hybrid system in removing various types of pollutants in POME at optimum temperature and able to fulfill the stringent effluent discharge limit. Chemical oxygen demand (COD), total solids (TS) and turbidity removals increase linearly with temperatures with removal efficiency of 0.5889% C À1 , 1.0754% C À1 and 0.7761% C À1, respectively. The temperature coefficient (Q 10 ) is found to be 1.06, 1.45 and 1.09, respectively. Besides, MFC-adsorption hybrid system had demonstrated superior stability over a wide range of operating temperatures in terms of COD removal as compared to the non-integrated MFC system.

The present study investigated seafood industrial wastewater treatment with corresponding power generation in air cathode microbial fuel cell under saline condition (40 g/L). The results recorded total chemical oxygen demand) removal of 52 ± 1.8%, 64 ± 1.1%, 85 ± 1.2%, 89 ± 1.4%, and 76 ± 1.2% to the corresponding organic load (OL) of 0.5, 0.75, 1, 1.25, and 1.5 gCOD/L under saline condition. Soluble chemical oxygen demand reduction was in the range of 46% to 78% at OL of 0.5 to 1.5 gCOD/L. The maximum power density (530 ± 15 mW/m 2) and coulombic efficiency (52 ± 2.4%) was procured at the OL of 1.25 and 0.5 gCOD/L, respectively. Total suspended solids removal was 74 ± 1.5% at OL of 1.25 gCOD/L and 64 ± 1.3% at OL 1.5 gCOD/L. Bacterial community analysis for anode region samples for OL 0.5 and 1 gCOD/L was extensively dominated by Bacillus (MN880233) with 75.8% and 55.8%, respectively. Interestingly at 1.25 gCOD/L OL, Rhodococcus (MN880237) was predominant (42.3%) strain in the anode region and recorded high power production under saline condition. Sludge samples subjected to phylogenetic analysis explored the dominance of Clostridium, Turicibacter, and Marinobacter at different OL from 0.5 to 1.5 gCOD/L. Bacterial community results at 1.25 gCOD/L of OL sludge samples revealed completely different strains of dominancy in the community. Marinobacter (53.3%), Ochrobactrum (19.3%), and Bacillus (8.1%). Thus, the phylogenetic analysis of the anodic and sludge samples clearly detailed the presence of halophilic bacterial strains with high potential to treat seafood processing industrial wastewater and excellent exoelectrogenic activity for power production.

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
