“…The experiments were carried out using three different thicknesses of the nanocomposite membrane, such as 100, 120, and 140 µm. The maximum power density of around 147 mW/m 2 was obtained for the membrane thickness of 120 µm (0.12 mm) [35]. Although the thinnest membrane was 100 µm but this study indicates the need to optimize the thickness of the membrane to minimize the internal resistance, ionic loss and maximize the permeability of electroactive species.…”

Microbial fuel cells (MFC) are an emerging technology for wastewater treatment that utilizes the metabolism of microorganisms to generate electricity from the organic matter present in water directly. The principle of MFC is the same as hydrogen fuel cell and has three main components (i.e., anode, cathode, and proton exchange membrane). The membrane separates the anode and cathode chambers and keeps the anaerobic and aerobic conditions in the two chambers, respectively. This review paper describes the state-of-the-art membrane materials particularly suited for MFC and discusses the recent development to obtain robust, sustainable, and cost-effective membranes. Nafion 117, Flemion, and Hyflon are the typical commercially available membranes used in MFC. Use of non-fluorinated polymeric membrane materials such as sulfonated silicon dioxide (S-SiO2) in sulfonated polystyrene ethylene butylene polystyrene (SSEBS), sulfonated polyether ether ketone (SPEEK) and graphene oxide sulfonated polyether ether ketone (GO/SPEEK) membranes showed promising output and proved to be an alternative material to Nafion 117. There are many challenges to selecting a suitable membrane for a scaled-up MFC system so that the technology become technically and economically viable.

“…Frontiers in Environmental Science frontiersin.org describes variability across multiple samples of a population (Sugumar et al, 2022). Hence, the standard error is a crucial concept in statistical inference because it measures the accuracy with which a sample represents a population, and it helps to determine the level of confidence we can have in the results obtained from a sample.…”

Introduction: Membrane fouling has been reported to be one of the bottlenecks of membrane technologies for wastewater treatment. To mitigate its negative impacts, we fabricated polysulfone membrane (PSf) composites made of silica (SiO2) and graphene oxide (GO) nanoparticles that modified with ultraviolet (UV)-assisted polyvinyl alcohol layer on the membrane surface.Methods: The membrane composite was synthesized using non-solvent induced phase separation (NIPS) method. The membrane was further treated by UV irradiation and cross-linked with PVA coating to cope with the fouling problem. The modified membrane was applied for industrial rubber wastewater decontamination.Results: The UV irradiation and cross-linked PVA coating to the PSf/GO-SiO2 membrane improved the pseudo-steady state permeate flux by 60.15% from 20.05 to 50.32 L/m2hr and maintained the permeate flux up to 82.33%. About 85% of total dissolved solids (TDS), 81% of chemical oxygen demand (COD), and 84% of ammonia compound (NH3) with initial concentrations of 335.76, 242.55, 175.19 mg/L, respectively, could be removed after 8 h of membrane treatment. The modified membrane also exhibited an excellent flux recovery ratio of up to 83%.Discussion: The modified membrane changed the fouling mechanism from pore blockage to cake filtration, which signifies the capability of the membrane to tackle severe fouling tendency. The cross-linked UV/PVA coating reduced fouling formation by reducing the adsorptive interactions between the foulant molecules and the membrane surface by enhancing membrane surface hydrophilicity. This implies that incorporating GO/SiO2 nanoparticles with UV irradiation and PVA coating substantially enhanced the physicochemical properties of the PSf membrane.

“…However, MFC operational parameters as experimental factors of RSM may limit the practical application of MFC. On the contrary, it may be a more feasible way to increase the performance of MFC by optimizing MFC materials with RSM, such as proton exchange membrane 22 and electrode material optimization 23 …”

Microbial fuel cells (MFCs) have the potential to remove copper ions from wastewater, but the high cost of their cathode materials and their limited effectiveness in removing copper ions have limited their commercialization. In this study, a composite cathode was developed using response surface methodology (RSM); peanut shells were used to produce biochar, which was compounded with conductive carbon black (CCB). When 83% of the cathode material was biochar, its resistance was low and its copper adsorption capacity was high. An MFC with such a composite cathode removed 95% of copper from wastewater within 5 days, which is 1.52 times more than that removed using a CCB cathode MFC. Although the power production capacity of the composite cathode MFC was slightly lower than that of the CCB cathode MFC, the composite cathode achieved 56% of the power output of the CCB cathode MFC using only 17% of the CCB, significantly reducing the cost of cathode production. The optimized composite biochar cathode that was developed using RSM provides both low resistance and a high copper adsorption capacity, and can be used in MFCs to improve their removal of copper ions from wastewater. This investigation also demonstrates the potential of agricultural waste as an electrode material in MFCs, reducing their production cost and improving their performance.
