Mathematical model of softened water pH correction process by electrodialysis with bipolar ion-exchange membranes
Keywords:

Abstract
The mathematical model describing of pH correction process of softened carbonate water in twocompartment
electrodialysis cell with bipolar and anion-exchange membranes is developed. The approach on
the base of out diffusion kinetic transport was used in model. This approach allows to calculate the
theoretical effective anions transfer numbers on the basis of ions concentrations, charges of ions and it
diffusion coefficients in solution without data about membrane properties and other empirical parameters.
