摘要： Electrodeionisation devices having low scale potential as well water treatment methods using the device are disclosed. The device may have a variety of configurations such as a first depleting compartment disposed between the anode compartment and the cathode compartment, a concentrating compartment in ionic coummunication with the depleting compartment, a second depleting compartment in ionic communication with the concentrating compartment and a first barrier cell in ionic communication with and disposed between the first depleting compartment and at lest one of the anode compartment and the cathode compartment. The device may also have configuration directed to the layering of the anionic exchange resin beads and/or have at l-east one compartment that provides a dominating resistance resulting in a uniform current distribution throughout the apparatus. Temperature control may be provided. It is also possible to arrange for parallel liquid flow.

摘要： An electrochemical treating device having low scale potential is disclosed. The device has a variety of configurations directed to the layering of the anionic exchange and cationic exchange. The treatment device can also comprise unevenly sized ion exchange resin beads and/or have at least one compartment that provides a dominating resistance that results in a uniform current distribution throughout the apparatus.
