ELECTROREGENERATION APPARATUS AND WATER TREATMENT METHOD
摘要
A water treatment apparatus that includes a cation exchange chamber containing a cation exchange resin and an anion exchange chamber containing an anion exchange resin. A bipolar interface is located between the resin chambers and defines a zone of water disassociation. A cathode communicates with the cation exchange chamber through a cation exchange membrane. An anode communicates with the anion exchange chamber through an anion exchange membrane. Dilution or flushing water flows through cathode and anode chambers and conveys captured ions to a drain or other waste connection. A baffle may be used in some configurations to divide a resin chamber into an exhausted resin region and a regenerated resin region and causes incoming water to flow through the exhausted resin region first. The exhausted resin region is located near its associated electrode, thus improving the electrical efficiency of the cell.
