Abstract
Abstract The system for removing ions from an ionized liquid of the type employing rotating bipolar electrodes wherein at least one of the electrodes is provided with a surface comprising a plurality of segments of electrically conducting material, each of which segments is electrically insulated from the other and with brush contact means to apply one polarity voltage to a plurality of segments on one side of the electrode and the opposite polarity voltage to a similar plurality of segments on the opposite side of the electrode to provide the voltage polarity difference between the two sides of the electrode to cause ion adsorption from one part of the ionized liquid and ion rejection to another portion of the ionized liquid.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
169 words
In a system for removing ions from an ionized liquid of the type employing a pair of adjacent rotating bi-polar electrodes having peripheral surfaces of selective ion adsorption material disposed in the ionized liquid and wherein electrically induced ion-adsorption takes place in one portion of the liquid, said ions are transported out of said one portion of the liquid by the rotation of the electrodes and rejected into another portion of the liquid, the improvement comprising: a. At least one segmented rotating electrode; and b. Brush contact means operatively associated with said segmented electrode and a direct current voltage source for applying one polarity voltage to a plurality of segments on one side of said segmented electrode and the opposite polarity voltage to a similar plurality of segments on the opposite side of said segmented electrode and establish a voltage polarity difference between the two sides of said segmented electrode to effect ion-adsorption from one portion of the ionized liquid and ion-rejection to another portion of the ionized liquid.
