A highly efficient water purification device includes a degasification apparatus, a distillation apparatus and an ion removal device to purify contaminated water. When a partial vacuum is applied to the degasification apparatus, dissolved gases leave the water, and a heat exchange process occurs which heats the gases and cools the degassed water. A gas exhaust channel transfers the warmed gases to a heating coil in the distillation apparatus to preheat water for evaporation therein while the cooled, degassed water is transferred to a condenser to condense vapor and steam. The degasification apparatus may include one or more towers in which a vacuum is formed by first filling the towers with water, sealing the tower top, and then draining water from the tower bottom; this vacuum may be applied to the distillation apparatus and a reservoir by transferring the vacuum from the towers through a depressurization conduit to thereby achieve boiling in the distillation apparatus at reduced temperatures. |
