Abstract

The present invention relates generally to the deionization of liquids through the use of electrodeionization methods and apparatuses. The apparatuses are configured to produce purified liquids having an ion content at a level of parts-per-trillion or less, and to provide continuous regeneration of the ion exchange materials. The apparatuses may be configured according to the desired levels of deionization for anions, cations, or both. Finally, methods are presented for various uses of the claimed apparatus.
