Patent ID: 7705061

Claim:
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 a) drying a nonporous cation resin, b) grinding said cation resin, c) optionally sieving said cation resin, d) impregnating said cation resin into a binding agent to form a cation resin mixture, e) partially drying said cation resin mixture, f) shaping said cation resin mixture, and g) drying said cation resin mixture; 2) preparing a nonporous anion resin side, wherein said nonporous anion resin side is formed by the steps of a) drying said a nonporous anion resin, b) grinding said anion resin, c) optionally sieving said anion resin, d) impregnating said anion resin into a binding agent to form an anion resin mixture, e) partially drying said anion resin mixture, f) shaping said anion resin mixture, and g) drying said anion resin mixture; 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.
