초록 ▼

The electrical efficiency of an electrically regenerated ion exchange system is improved by using elongated ion exchange members having a continuous ion exchange phase that is more conductive in the exhausted form than it is in the regenerated form. Preferably, the system includes anion exchange members that extend through the wall of the demineralization compartment closest to the anode but do not extend through the wall of the demineralization compartment closest to the cathode, and cation exchange members that extend through the wall of the demineralization compartment closest to the cathode but do not extend through the wall of the demineralization compartment closest to the anode.

대표청구항 ▼

An electrically regenerated ion exchange system comprising: an anode compartment and a cathode compartment; a first demineralization compartment positioned intermediate said anode and cathode compartments and adjacent to said anode compartment; a second demineralization compartment positioned intermediate said anode compartment and said cathode compartment and adjacent to said cathode compartment; at least one waste compartment between said first and said second demineralization compartments; said first demineralization compartment containing a plurality of elongated cation exchange members having first ends extending towards said anode compartment and second ends exposed to a waste compartment positioned between said first and second demineralization compartments and adjacent to said first demineralization compartment, and a plurality of elongated anion exchange members having first ends that are exposed to said anode compartment and second ends that extend towards but are not exposed to said waste compartment adjacent to said first demineralization compartment; said second demineralization compartment containing a plurality of elongated anion exchange members having first ends extending towards said cathode compartment and second ends exposed to a waste compartment positioned between said first and second demineralization compartments and adjacent to said second demineralization compartment, and a plurality oF elongated cation exchange members having first ends that are exposed to said cathode compartment and second ends that extend towards but are not exposed to said waste compartment adjacent to said second demineralization compartment.
