Сalculation of Concentration Polarization in Electromembrane Devices with Spiral Wound Modules

Abstract

The article presents the results of calculating the concentration polarization values for electric baromembrane separation of electroplating wastewater based on solving the Nernst–Planck and Poisson–Boltzmann equations with determining the concentration field along the length and height of the intermembrane channel. The dependence of concentration polarization on the solution flow rate, transmembrane pressure, temperature and concentration was analyzed.
