An apparatus and method for fluid distillation in general, and in particular, of water, adapted for consumer or home use, but capable of being made and operated so that it is suitable for separating solvents and solutes and other industrial use. The apparatus includes a housing having divider structure to form one or more compartments for receiving water to be distilled. The divider structure also presents a fluid passage for receiving water vapor which is formed when the upper portion of the water in the housing is boiled by a heater. An aerator is provided in the housing below the heater and in a location within the water compartment. The aerator operates to direct air under a slight pressure into the water so that air bubbles can be generated in the water. The air bubbles will rise and break the surface of the water as the upper part of the water is being boiled by the heater. This causes a vapor pressure to be generated in the space above the water level and water vapor is then caused to move through the fluid passage downwardly to a lower chamber in which the water vapor is collected as a condensate. As the water vapor moves downwardly in the fluid passage, it moves in heat exchange relationship to the water in the compartment of the housing. Several embodiments of the housing of the present invention are disclosed herein.

A method of distilling a liquid comprising: providing a vertical column of a liquid in a substantially quiescent condition with the liquid having an upper surface, there being an upper space above the upper surface, the upper surface of the water being the interface between the liquid and said upper space; aerating the liquid to cause a rising stream of gas bubbles to form in the liquid column at a first location near the lower end of the liquid column; boiling the liquid at a second location near the upper surface thereof, said boiling step including applying heat energy to a region within the liquid column so that the heat energy is directly applied to the liquid, said boiling step occurring as the gas bubbles are formed and rise to thereby form vapor at a vapor pressure sufficient to cause the vapor to pass through said interface and into said upper space; channelling the stream of rising gas bubbles to said second location, the rising gas bubbles in the liquid and the boiling of the liquid being the only activity causing motion of the liquid in said column; allowing the vapor to move into heat exchange relationship to the liquid column to condense the vapor to form a condensate; and collecting the condensate.
