Abstract
A method is disclosed for encapsulating and solidifying spent ion exchange beads contained in a container to form an ion exchange bed with a solidification resin without the necessity for applying shear in the bed by an external force such as by a mixing impeller. A solidification resin is flowed through the ion exchange bed by plug flow to intermix with and encapsulate each ion exchange bead therein. The resin is cured to form a uniform, solidified monolith of said ion exchange beads in said container. When the ion exchange bed contains free water, the process also effects the removal of substantial portions of the free water and also emulsifies and solidifies free water remaining in the bed.
