A scraped heat exchanger apparatus, including a vessel and a plurality of internally cooled plates disposed parallel to each other within the vessel. A rotating shaft is disposed at a central axis of the vessel. A rotating scraper arm, connected to the rotating shaft, moves between adjacent plates. The rotating scraper arm includes a scraper positioned to scrape solids from the outer surfaces of adjacent plates. A cooling fluid flows through an interior of each plate. The cooling fluid cools a gaseous process fluid flowing between adjacent plates. An opening in each of the plates permits the process fluid, and solids removed from the process fluid and scraped by the rotating scraper arm, to pass through the plates.

Embodiments of the present invention are directed to a cryo-thermal desalinator, which addresses thermal desalination inefficiency by introducing intrinsic cooling potentials of strategically-piped liquidized gasses to save fuel and increase potable water output. Liquid natural gas fuel flows through internally routed, uninsulated and dedicated piping to natural gas brine burners located outside and under a vessel. The liquid natural gas fuel contributes to condensation and converts to eventual pre-warmed natural gas at the brine burners. Liquid gas flows through an internally routed, closed-loop piping to continually provide condensation, while a liquid gas compressor of the closed-loop exhausts waste heat to assist brine conversion. Saline water piping inside the vessel implements cooling via an optional alternative cooling heat exchanger, accepting portable liquid nitrogen, liquid CO.sub.2 dry ice, or both. The cryo-thermal desalinator's multi-cooling liquid gas systems accommodate multi-thermal inputs, assisting with unfired production of thermal desalination water vapor in real time.

Atmospheric water generators, systems and methods are presented involve user authentication, recording and tracking of water volumes dispensed by respective users over periods of various lengths, controlling component noise level and timing, and cleaning, heating and cooling the collected water more efficiently. The generators may be placed in network communication with other such generators to exchange water availability information therewith, or may communicate with a central server element by way of LAN, Internet, cell tower, peer-to-peer mesh or satellite. Information is conveyed to the user regarding the amount of water they consume from the water generators, and their resulting positive impact on the environment. Water dispensing data may be shared on the users' social media accounts, or used as inputs for competitions or games in order to further engage the user. User authentication may be accomplished by way of biometrics or an RFID/NFC tag embedded in the user's water vessel.

A moisture trap for removing liquid from a fluid drawn from a tissue site treated with reduced pressure and systems and methods for using the same are described. The moisture trap may include a barrier adapted to be fluidly coupled to and define an indirect fluid path between a fluid reservoir and a reduced-pressure source. The barrier may have a hydrophilic surface. The moisture trap also may include a sump adapted to receive condensation from the barrier.

Systems, devices, and methods are described herein for generating liquid water from water vapor present in the atmosphere through use of selectively permeable films that permit water to pass through but that block other liquids and gases, such as atmospheric gases. The systems, devices, and methods employ condensation techniques in which only the water that is passed through the selectively permeable film is cooled, as compared to other atmospheric water generation systems, which cool water and other gases that enter with the water.

A low energy fluid purification system and method of implementation including some embodiments having a vacuum-rated first chamber placed in or near a body of water with higher temperature near the surface and lower temperatures at greater depths. The vacuum-rated first chamber holds a quantity of non-potable water and a low pressure area less than or equal to the water's vapor pressure. Vaporization occurs when the higher temperature surface water is brought into contact with the low pressure area. A tubular vapor transport passage allows the vaporized water to pass to a lower temperature and lower pressure condensation chamber. The lower temperature condensation chamber is cooled by lower temperature water from a selected depth below the surface. As the temperature of the vapor lowers, the vapor will condense. This condensation is collected as a quantity of potable water. Additional embodiments and methods are also provided.
