Reverse Electrodialysis in Charged Capillary Membranes

Abstract

A detailed study of the transport properties of charged capillary membranes in the reverse electro-dialysis mode of operation is presented. The compromising assumptions of linearized Poisson–Boltzmann equation, large radius to Debye length ratio, and small concentration difference made by some investigators are relaxed. For various tube sizes, wall charge densities, and solutes, results are presented for the operating characteristics of the membrane as functions of transmembrane concentration ratio.
