Abstract
Electrochemical devices and methods for water treatment are disclosed. An electrodeionization device () may include one or more compartments () containing an ionselective media, such as boron-selective resin (). Cyclic adsorption of target ions and regeneration of the media in-situ is used to treat process water, and may be driven by the promotion of various pH conditions within the electrochemical device.
