ANALYSIS AND DETERMINATION OF THE OPTIMAL PROCESS PARAMETERS OF ELECTRODIALYSIS PURIFICATION OF SOME CHEMICAL-INDUSTRY SOLUTIONS

The problem of determining the optimal parameters of the process of electrodialysis purification of wastewater generated during the production of printed circuit boards is considered. To increase the completeness of separation, the choice of the maximum current density and the thickness of the diffusion boundary layer in the ionite membrane system is substantiated. The problem is choosing the optimal parameters of the electrodialysis separation process is formulated. An example of calculating the optimal separation parameters for a single-component copper sulfate solution is presented. A graph of the flow region with optimal operating parameters of the electrodialysis unit is constructed depending on the sizes of the membranes
