Abstract

Electrodialysis is a water treatment and wastewater treatment technology that uses an electric field gradient and ion exchange membranes to separate ions in aqueous solutions. Studies conducted using this technology have shown the influence of the hydrodynamic regime on the efficiency of the process, the rate of mass transfer and polarization concentration. The article presents experimental results, mathematical calculations and numerical modeling in the universal software system of analysis by the Ansys finite element method. Theoretical calculated results show a good correlation with the results of hydrodynamic processes in the apparatus obtained experimentally. The hydrodynamic regime in the channel of the electrodialyzer cell has been studied, the influence of the mesh geometry on the distribution of fluid flow over the membrane surface has been shown, and the change in flow velocity and pressure depending on the structure of the mesh has been described.

Keywords
