Abstract: Spent nuclear reactor coolant system decontamination solutions are first processed to remove the radioactive burden and to separate metallic impurities using cation exchange resins. The cation-processed waste solution is then flowed through an anion exchange resin held between anion-permeable membranes within an electrochemical cell. The application of electric current to the electrochemical cell causes hydroxide ions to replace captured anions held on the ion exchange resin, thereby regenerating the anion exchange resin for subsequent processing. The displaced anions migrate into the anode compartment where they can be oxidized to carbon dioxide for simple disposal.

Abstract: An electrode used in electrochemical deionization comprises a current feeder disposed asymmetrically in an ion exchange material bonded into a coherant structure i.e. more of the ion exchange material adheres to one side of the current feeder than to the other side. The ion exchange material may be bonded by being provided in intimate admixture with a binder. Such an electrode offers manufacturing ease and the ability to be scaled up in multi-modular form.

Abstract: Process and apparatus are provided for demineralizing aqueous solutions without using regenerating chemicals. Oppositely charged ions are electrolytically generated within electrode chambers and diffused into the stream of aqueous solution to be demineralized flowing in cross-current thereto. In their migration in response to the application of an electric potential, the ion streams are subjected to displacement steps in cation and anion exchange masses separated by selectively permeable ion exchange membranes. The aqueous solution alternately passes through the cation and anion exchange masses resulting in a demineralized aqueous stream and an enriched brine stream.

Abstract: This disclosure relates to the electrodialytic demineralization of water by passing soft water through a treating chamber defined by a pair of permselective membranes of which the one closer to the cathode of the cell is cationic permselective and the one closer to the anode is anionic permselective. The chamber is charged with an ion exchange material. The effluent from the treating chamber may be passed through a second like treating chamber. The ion exchange materials with which the cell or cells are charged may be cationic, anionic, both cationic and anionic, or cationic in one chamber and anionic in another chamber where more than one treating chamber is employed. The particular types of ion exchange materials selected will depend upon the flow pattern and arrangement of chambers in different electrodialytic cells embodying the invention.

Abstract: The invention described herein is a process for the purification of carbon. That process provides for the treatment of carbon with hydrofluoric acid, or a mixture of hydrofluoric acid and nitric acid, followed in each case by treatment with hot aqueous hydrochloric acid. The carbon thus purified is notably effective for use as electrode material in a demineralization cell, i.e., one used for the demineralization of water.

Abstract: An ion-exchange apparatus has a raw-water tank 1, a treatment tank 2, an ion exchanger 3 and a voltage applying device E. The raw-water tank 1 contains a to be treated liquid that has impurity ions. The treatment tank 2 contains a treatment material with exchange ions exchangeable with the impurity ions. The ion exchanger 3 enables the passage of the impurity ions from the raw-water tank 1 to the treatment tank 2 and the passage of the exchange ions from the treatment tank 2 to the raw-water tank 1. The voltage-applying device E applies a voltage to the ion exchanger 3.
