Claim 3
Dependent Claim
139 words
IN A PROCESS FOR THE CONTINUOUS FRACTIONATION BY ELECTRODIALYSIS OF ELECTRICALLY CONDUCTIVE AND ELECTRICALLY NON-CONDUCTIVE FLUIDS IN A MULTI-CHAMBER APPARATUS COMPRISING, ELECTRODE CHAMBERS CONTAINING AN ELECTROLYTE, AND INTERMEDIATE TREATMENT CHAMBERS SEPARATED FROM THE ELECTRODE CHAMBERS, AND FROM ONE ANOTHER, BY PERMSELECTIVE MEMBRANES, THE STEPS OF INTRODUCING THE FLUID TO BE TREATED INTO THE INTERSTICES OF AN ION CONDUCTIVE FILLER OCCUPYING THE SPACE BETWEEN THE BORDERING MEMBRANES OF ADJOINING CHAMBERS, DRIVING IONS ORIGINATING IN AN ELECTROLYTE EXTERNAL WITH RESPECT TO SAID FILLER INTO AND THROUGH SAID FILLER, THE FILLER HAVING AN ION-TO-SOLVENT TRANSFER RATIO FOR THE DRIVING IONS DIFFERENT FROM THE ION-TO-SOLVENT TRANSFER RATIO FOR THE SAME IONS OF AT LEAST ONE OF THE BORDERING MEMBRANES, AND WITHDRAWING THE FRACTIONS FROM THE FILLER CONTAINING CHAMBER FROM ZONES SPACED IN THE DIRECTION OFF THE FLOW OF ELECTRIC CURRENT THROUGH THE APPARATUS.
