Abstract

An ion exchange resin regeneration apparatus. A nine compartment module has two end anode electrode compartments and a center cathode electrode compartment. These three compartments contain a mixture of cation and anion resin. The two end compartments are lined by cation membranes while the center compartment is lined on both sides by anion membranes. All but two of the remaining compartments are provided with cation or anion exchange resin and opposing cation and anion membranes in an arrangement whereby a resin slurry may be consecutively directed through two of the compartments for processing.
