ABSTRACT:
The invention disclosed is a process and apparatus for reducing the concentration of dissolved contaminant in a contaminated liquid, with specific application to the regeneration of contaminated electrolyte in an electrolytic cell, wherein the electrolyte is removed from the cell under vacuum and mixed with a washing liquid e.g. water and clean electrolyte. The mixed electrolyte is returned to the cell and the process repeated until the contaminant concentration in the washing liquid and electrolyte are substantially the same.
