The temperature modes of operation of ion-exchange membranes in an electrodialysis apparatus are described. The diffusion permeability of the MK-40 ion-exchange membrane has been experimentally investigated under the conditions of a temperature difference across the membrane at various concentrations of an aqueous solution of sodium chloride. The differences in the diffusion permeability of the membrane in thermostatic and thermodynamic modes are shown. The nature of the influence of the temperature drop across the membrane of aqueous sodium chloride solutions on changes in the value of the diffusion permeability coefficient of the MK-40 membrane was determined.
