ABSTRACT:
A water purification and/or collection method uses a water-specific reaction with an anhydrous salt to separate organic and inorganic contaminants in a water supply. A stream of water vapor containing the contaminates is passed over a desiccant bed of anhydrous salt. Only the water in the stream reacts to form hydrates while the contaminates pass by in an air stream for disposal elsewhere. The fully hydrated bed is then regenerated by heat to free the purified water which is condensed.
