Water purification system and process

A processor for removing contaminates from contaminated water comprising:

• a) a hermetically sealed housing capable of holding a near-vacuum pressure up to above atmospheric pressure at which contaminated water boils at the near-vacuum pressure up to above atmospheric pressure;
• b) a boiler-condenser unit mounted in the hermetically sealed housing, the boiler-condenser unit having at least one shell of heat-conductive material mounted for rotation about a longitudinal axis of rotation, each of the at least one shell being generally parallel to the longitudinal axis of rotation, each of the at least one shell having an inside, boiler surface facing toward the longitudinal axis of rotation and an outside, condenser surface facing away from longitudinal axis of rotation;
• c) a source of contaminated water flowing inside the boiler-condenser unit to the inside, boiler surface of each shell, the inside, boiler surface of each shell boiling contaminated water from the inside, boiler surface at the vacuum pressure in the hermetically sealed housing to convert at least some contaminated water into vapor;
• d) a compressor having a lower-pressure side and a higher-pressure side, the compressor being mounted to receive vapor boiled on the inside, boiler surface of each shell to raise the vapor's pressure from the lower-pressure side to a higher-pressure side, the compressor being mounted to direct the higher-pressure vapor to the outside, condenser surface of each shell so vapor striking the outside, condenser surface condenses on the outside, condenser surface of each shell;
• e) a framework assembly mounted radially outside relative to the axis of rotation of a shell, the framework assembly creating a condenser chamber between the framework assembly and the outside, condenser surface of the shell;
• f) a motor operably connected to each shell for rotating each shell;
• and
• g) at least one wiper positioned in contact with at least one condenser surface, the at least one wiper removing condensate from the outside, condenser surface as the outside, condenser surface rotates past the at least one wiper.
• h) at least one wiper positioned in contact with at least one boiler surface, the at least one wiper filming the boiling fluid and removing wastewater from the inside, boiler surface as the inside, boiler surface rotates past the at least one wiper.

A process for removing contaminates from contaminated water comprising:

• a) evacuating a housing to a near-vacuum pressure at which water boils at ambient temperature;
• b) rotating a boiler-condenser shell mounted in the housing about a longitudinal axis of rotation, the boiler-condenser shell having an inside, boiler surface and an outside, condenser surface, the inside boiler surface being closer than the outside, condenser surface to the longitudinal axis of rotation;
• c) directing the vapor generated from boiling inside the boiler- condenser shell to a compressor;
• d) raising the pressure of the vapor within the compressor;
• e) directing the elevated-pressure vapor from the compressor to the outside of the boiler-condenser shell whereby the vapor condenses on the outside of the boiler-condenser shell, the condensation transferring heat energy to the boiler-condenser shell;
• f) wiping at least some of the condensate from the outside of the boiler-condenser shell;
• g) collecting the condensate from the boiler-condenser shell;
• and
• h) collecting any contaminated water that did not boil from the inside boiler surface.

A processor for obtaining potable water from contaminated water comprising:

• a) a vacuum housing capable of holding a near vacuum;
• b) a boiler-condenser assembly in the vacuum housing subjected to the near vacuum in the vacuum housing, the boiler-condenser assembly comprising at least two concentrically mounted shells of heat-conductive material rotating together about a longitudinal axis of rotation, each shell of the at least two concentrically mounted shells having an inside, boiler surface and an outside, condenser surface;
• c) a compressor mounted in the vacuum housing, the compressor having a lower-pressure side and a higher-pressure side, the compressor being mounted to receive vapor boiled on the inside, boiler surface of each shell, the compressor being mounted to direct the higher-pressure vapor to the outside, condenser surface of each shell so vapor striking the outside, condenser surface condenses on the outside, condenser surface of each shell;
• d) an inlet extending from a source of contaminated water to at least one outlet close enough to the inside, boiler surface of each shell so contaminated water exiting the inlet can reach the inside, boiler surface, the inside, boiler surface of each shell being capable of boiling contaminated water from the inside, boiler surface at the vacuum pressure in the housing to covert contaminated water into vapor;
• e) the compressor increasing the vapor's temperature passing through the compressor sufficiently to supply enough energy through each shell to boil water on the inside, boiler surface of the shells;
• and
• f) a motor operably connected to each shell and the compressor for rotating the compressor and shell.
