    Abstract: In a method and apparatus for operating and regenerating ion exchange material a wash fluid or elution solution for rinsing the ion exchange material (1) is prepared, there is collected as a by-product of said preparation a first waste stream including cationic species to be eliminated, the ion exchange material (1) is subjected to a wash step in which there is eluted from the ion exchange material by the wash fluid or solution an anionic species to be eliminated and a second waste stream including the anionic species to be eliminated is obtained, the first waste stream (12) and the second waste stream (14) are combined to form a precipitate SW comprising a reaction product of said cationic species and said anionic species, and the precipitate is removed. The method provides an efficient means of eliminating undesired species from a circuit containing an ion exchange material to be regenerated.

    Abstract: A weak acid resin which is exhausted by contact with bases is regenerated by contact with carbonic acid formed by introducing carbon dioxide into water under a pressure of from 100 to 300 psi. The carbonic acid is capable of regenerating the sodium form of the weak acid resin. The sodium bicarbonate from the regeneration of the weak acid resin is then degassed to eliminate the carbonic acid or CO2 and the remaining sodium bicarbonate is used to regenerate a weak base anion resin. The ion exchange beds are then run in reverse, that is, the anions are exchanged before the cations.

    Abstract: A metal ion recovery system first removes most of the plating solution from recently plated articles in a relatively concentrated form and removes the remainder of the solution in much less concentrated form. These solutions are treated separately with only the lower concentrated solution being completely deionized to remove said metal ions therefrom.
