Abstract:
1. A method for constructing an ion exchange media, comprising the steps of 1) preparing a nonporous cation resin side, wherein said nonporous cation resin side is formed by the steps of 2) preparing a nonporous anion resin side, wherein said nonporous anion resin side is formed by the steps of 3) combining said anion resin side and said cation resin side such that they meet at an interface to form a nonporous resin transport framework, said transport framework including at least one void extending longitudinally through said transport framework at the interface and along the length of the transport framework; and 4) filling said void with a plurality of alternating layers of a porous second cation resin and a porous second anion resin to form at least one flow path.
