Theory of ion transport with fast acid-base equilibrations in bioelectrochemical systems.
Bioelectrochemical systems recover valuable components and energy in the form of hydrogen or electricity from aqueous organic streams. We derive a one-dimensional steady-state model for ion transport in a bioelectrochemical system, with the ions subject to diffusional and electrical forces. Since most of the ionic species can undergo acid-base reactions, ion transport is combined in our model w...
متن کاملUnderstanding Ammonium Transport in Bioelectrochemical Systems towards its Recovery
We report an integrated experimental and simulation study of ammonia recovery using microbial electrolysis cells (MECs). The transport of various species during the batch-mode operation of an MEC was examined experimentally and the results were used to validate the mathematical model for such an operation. It was found that, while the generated electrical current through the system tends to aci...
متن کاملModeling the ion transfer and polarization of ion exchange membranes in bioelectrochemical systems.
An explicit numerical model for the charge balancing ion transfer across monopolar ion exchange membranes under conditions of bioelectrochemical systems is presented. Diffusion and migration equations have been solved according to the Nernst-Planck Equation and the resulting ion concentrations, pH values and the resistance values of the membrane for different conditions were computed. The model...
متن کاملExcess Physical Limitations Among Adults
RESULTS — People with diabetes had a higher proportion of any physical limitation than did people without diabetes overall (66 vs. 29%, P 0.001), for both men (59 vs. 24%, P 0.001) and women (72 vs. 34%, P 0.001). Compared with those without diabetes, a higher proportion of people with diabetes had some physical limitation among all age groups, and the difference declined (all P 0.001) with inc...
متن کاملMicrobes Facilitate Mineral Deposition in Bioelectrochemical Systems
Hydrothermal chimneys are striking, characteristic features of marine hydrothermal vents. These chimneys are dynamic environments occupied by a diversity of microbes whose distribution is typically concordant with mineralogy and temperature. Recent studies indicate that these chimney assemblages are conductive and present the possibility that microbial extracellular electron transfer may occur ...
