ABSTRACT:
Composite electrode structures are disclosed employing mutually opposed electrodes spaced apart to define a fluid treatment region through which a fluid is passed for treatment by an electric field established between the electrodes. Resistive electrodes serve to localize the effect of electrical shorts between the electrodes. Refractory electrodes and insulators permit operation in high temperature environments. Non-uniform sheet and/or filamentary electrodes are disclosed for producing a substantial non-uniformity in the electric field within the treatment region for producing forces on particles having no net charge. A floating electrode between driven electrodes allows formation of an induced electric field in the treatment region while reducing the possibility of electrical shorts. Paper electrodes and paper insulators permit fabrication of an inexpensive electrode structure. Moisture is removed from the treated fluid by loading either or both the insulator and electric structures with a hygroscopic electrolyte and passing a current through the electrolyte to convert the moisture into elemental oxygen and hydrogen.
