This invention presents an ion exchange media including a plurality of
cation exchange zones and anion exchange zones in flow paths that are
contained in a substantially nonporous resin transport framework. During
electrodeionization and other potential applications the ion exchange
media of the invention prevents unfavorable water splitting at
resin-membrane interfaces and encourages water splitting at resin-resin
interfaces where the water splitting may be constructively used to
regenerate the resin.
