Abstract:
1. A system for converting polluted water from a reservoir for polluted water to purified water and delivering said purified water to a reservoir for purified water, said system comprising: a conduit means for drawing polluted water from said reservoir of polluted water; an entry chamber having an entry port communicating with said conduit means; a vapor chamber communicating with said entry chamber; a passageway having an entrance communicating with said vapor chamber; a pump having an input communicating with said passageway and an output arranged for delivering purified water to said reservoir for pure water; an air-tight enclosure enclosing said entry chamber, vapor collection chamber, passageway and pump; and said system arranged to provide that said pump reduces air pressure in said entry chamber, vapor collection chamber and passageway thereby drawing polluted water from said reservoir of polluted water, and draws water vapor from said polluted water in said entry chamber, collects said vapor in said vapor collection chamber, condenses said vapor to purified water in said passageway, and discharges said pure water into said reservoir for purified water; a section of wall of said entry chamber being a barrier wall, bounding said entry chamber on one side of said barrier wall, and bounding said passageway on another side of said barrier wall; said barrier wall positioned inclined to horizontal; means for directing said polluted water to flow from a top boundary of said entry chamber inside said entry chamber down an inclined surface of said barrier wall providing that water vapor abetted by reduced air pressure, is generated from water flowing down said inclined surface in said entry chamber; said pump drawing said vapor through said vapor collection chamber then into said passageway where condensation of said vapor generates purified water; said purified water flowing through said pump to said reservoir for purified water; a valve means for controlling flow of polluted water from said conduit means into said entry chamber; and said conduit means comprises: said valve means comprises: when said plate is in a second position:, said source opening is means for locating said plate in anyone of said first and second position.
