Abstract: | In order to design the technological process of desalination by electrodialysis for the industrial wastewater of an alumina
plant, the limit current density of the industrial wastewater is measured, and the equations of limit current density, voltage
drop of the unit membrane pair at the limiting current and desalination ratio at the limiting current were obtained.
