Abstract:
1. An electrodeionization device having an ion concentration compartment, ion depletion compartment, and first and second fluid flow paths that flow parallel between the ion concentration and ion depletion compartments but flow serially within each compartment, the electrodeionization device comprising: i) an anode assembly having one or more of electrode plates; ii) a cathode assembly having one or more of electrode plates; and iii) a channel grouping, including one or more ion depletion compartments arranged in an alternating sequence with one or more ion concentration compartments, the channel grouping interposed between the anode and cathode assembly wherein each anode and cathode assembly is paired with only one channel grouping, wherein said second fluid flow path configured to introduce fluid into and release fluid from each said ion concentration compartment substantially contemporaneously.
