MATHEMATICAL SIMULATION OF ELECTRIC BAROMEMBRANE SEPARATION OF POTASSIUM SULFATE SOLUTION IN A FLAT-CHAMBER APPARATUS

A combined approach is suggested to the mathematical simulation of electric baromembrane separation of potassium sulfate solution with varying transmembrane pressure and a fi xed value of current density, which consists of using material balance equations for the solvent, dissolved substance, and empirical dependences for kinetic coeffi cients. A static mathematical model of the process of electric baromembrane separation of potassium sulfate solution in a fl at-chamber apparatus with permeate outfl ow through two semi-permeable walls has been developed, which makes it possible to calculate the target indicators of the electric baromembrane system (volumetric fl ow rate and total salt content of the dissolved substance in the retentate)
