“…The water in the anode chamber is transferred to the middle chamber leading to the dilution of water and desalination in the middle chamber . Also, another influential factor is the driving force generated by the electric current of the exoelectrogenic bacteria from the anode chamber environment . The desalination efficiency of water at different initial salt concentrations (5, 25, and 35 g/L NaCl) at 24, 48, and 72 h HRTs is shown in Figure .…”

The Caspian Sea is one of the largest water sources located in the north of Iran; so this research was carried out to investigate the new design of microbial desalination cell (MDC) (double layer) efficiency in water desalination and power generation of the enormous saline water source in the north of Iran. Actual (i.e., Caspian Sea) and artificial seawater with different initial salt concentrations (5, 25, and 35 g/L NaCl) and, different hydraulic retention times (24, 48, and 72 h) in batch and open circuit voltage (OCV) mode were examined. In addition, the oxidation and reduction processes during desalination of each stage were monitored at 10 min intervals for 60 min. According to the obtained experimental data, both the desalination efficiency and the power generation decreased from 65 ± 1% to 41 ± 1% and 80 ± 4.5 mW/cm2 to 51.20 ± 2.5 mW/cm2 by increasing the retention time from 24 to 72 h for Caspian Sea water and 5 g/L NaCl, respectively. Maximum and minimum desalination efficiencies were 48 ± 1% and 65 ± 1% for Caspian Sea water and 5 g/L NaCl, respectively. Moreover, the maximum power densities were 72.83 ± 3.36 mW/cm2 and 80.00 ± 4.00 mW/cm2 for 35 g/L NaCl and seawater, respectively. As far as the authors know, this is the first study on the application of the new designed stacked MDC for power generation and desalination of water from the Caspian Sea. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019

“…An obvious approach to solve all problems related to the use of membranes is evolving to MFC configurations that do not require two chambers: single chamber or membrane-less MFC [28,29]. Nevertheless, most membrane-less MFC have some kind of separator such as polymers or other materials and typically use an air-cathode that requires a separator material assembled with cathode electrode on anolyte–facing side and on external-cathode facing side (diffusion layer).…”

Microbial fuel cells (MFCs) can evolve in a viable technology if environmentally sound materials are developed and became available at low cost for these devices. This is especially important not only for the designing of large wastewater treatment systems, but also for the fabrication of low-cost, single-use devices. In this work we synthesized membranes by a simple procedure involving easily-biodegradable and economic materials such as poly (vinyl alcohol) (PVA), chitosan (CS) and the composite PVA:CS. Membranes were chemical and physically characterized and compared to Nafion®. Performance was studied using the membrane as separator in a typical H-Type MFCs showing that PVA:CS membrane outperform Nafion® 4 times (power production) while being 75 times more economic. We found that performance in MFC depends over interactions among several membrane characteristics such as oxygen permeability and ion conductivity. Moreover, we design a paper-based micro-scale MFC, which was used as a toxicity assay using 16 μL samples containing formaldehyde as a model toxicant. The PVA:CS membrane presented here can offer low environmental impact and become a very interesting option for point of need single-use analytical devices, especially in low-income countries where burning is used as disposal method, and toxic fluoride fumes (from Nafion®) can be released to the environment.

This work considers the effects of various carbon nanomaterials and fibres on bioelectrocatalytic and respiratory activity of bacterial cells during the oxidation of ethanol in the presence of an electron transport mediator. Gluconobacter oxydans sbsp. industrius VKM B-1280 cells were immobilised on the surfaces of graphite electrodes and had an adsorption contact with a nanomaterial (multi-walled carbon nanotubes, thermally expanded graphite, highly oriented pyrolytic graphite, graphene oxide, reduced graphene oxide). The electrochemical parameters of the electrodes (the polarisation curves, the value of generated current at the introduction of substrate, the impedance characteristics) were measured in two-electrode configuration. Modification by multi-walled carbon nanotubes led to the increase of microbial fuel cell (MFC) electric power by 26%. The charge transfer resistance of modified electrodes was 47% lower than unmodified ones. Thermally expanded and pyrolytic graphites had a slight negative effect on the electrochemical properties of modified electrodes. The respiratory activity of bacterial cells did not change in the presence of nanomaterials. The data can be used in the development of microbial biosensors and MFC electrodes based on Gluconobacter cells.
