Local characteristics of mass transfer under electrodialysis demineralization Original Research Article

Electrodialysis with ion exchange membranes is one of the most important membrane methods, which deals with the problems of desalination of salted waters, waste water minimization, production of ultra-pure water, concentration of dilute solutions, separation of electrolytes and non-electrolytes and with the production of acids and alkalis from their salts. Mathematical modelling and laser interferometry have been applied for calculation and visualisation of local characteristics under electrodialysis demineralization.
