ABSTRACT:
According to the present invention there is provided an improved electrodialysis device comprising an electrodialysis stack with an anode compartment adjacent one end of the stack, a cathode compartment adjacent the other end of the stack, said electrode compartments being connected with each other by means of conduits, means being provided for circulating a slurry of carbon particles between the two electrode compartments. The slurry comprises finely powdered active carbon in an electrolyte, either by itself or in combination with finely powdered ion-exchange resin. The electrode compartments can be provided with inserts defining constrictions for the outflow of the slurry at the lower part of the inserts thus establishing a higher concentration of the particles at the lower part of the compartment. The invention further relates to an eletrodialysis process wherein a slurry of carbon particles is circulated between the electrode compartments.
