ABSTRACT:
The extraction of polar substances, such as pure water, from a solution containing such substances is carried out in an electrical process that closely resembles natural evaporation. By exposing the solution to a closely spaced, electrically charged surface, the liquid molecules of the substance become sufficiently excited and attracted to break through the surface tension and migrate to the charged surface where they accumulate. Alternative embodiments disclose modified means for conveying the extracted substance from the treating area.
