Design Development and Technological Calculation Technique of a Combined Electric Baromembrane Apparatus for Separating Solutions of Chemical Production

The paper presents the developed design of a combined electric baromembrane apparatus for the separation, concentration, and purification of industrial solutions and effluents. The separation of the solution is implemented in two stages: at the first stage, the solution passes through a flat-chamber module; at the second stage — through a tubular module, providing a high degree of solution purification. In addition, a procedure for calculating the separation area, the volume of the separated solution in the flat-chamber and tubular modules, as well as the volume of collectors for cathode and anode permeates of the tubular module, was developed. Calculations of the average permeability along the length of the membrane and the total electric power consumption for the separation of galvanic process solutions containing salts of heavy metals were performed.
