Accurate Determination of Electrical Potential on Ion Exchange Membranes in Reverse Electrodialysis

Reverse electrodialysis is a promising membrane technology to generate energy from controlled mixing of water streams different salinities. Electrical potentials on the ion exchange membranes (IEMs) when selective transport cations and anions across driven by concentration difference. The accurate determination developed IEMs critical fairly assess feasibility technology. Nernst–Planck–Poisson (NPP) equations for (the with fixed charge) were solved numerically boundary updating scheme. validity this numerical method was verified identical values Donnan potential obtained well-established analytical methods. suitability applicability classic Teorell–Meyer–Siever (TMS) model assessed comparison simulation results method.
