Abstract: A water desalinator that employs the use of solar concentration, evaporation and humidification, mimicking the natural hydrological cycle in a closed, modular vessel to produce freshwater from salt, brackish, brines and seawater, and a concentrate stream for further processing. Feed water is received and stored in a basin. Surface humidity is generated by the evaporation of basin water. A lens is used to focus sunlight, tracked the suns path based on biomimicry of a sunflower, on a thermal conductor. The thermal conductor has a rounded side-profile and generates a variable temperature across its radius. Water is pumped from the basin to a sprinkler head to be dripped or sprayed on the thermal conductor to generate water vapour. This water vapour consequently mixes with the air in the reaction vessel to increase system humidity. Humid air is removed from the reaction vessel and condensed in a condenser. Accordingly, the salinity concentration of input water is reduced from the output of the reaction vessel.

Abstract: The invention provides a method and apparatus for purifying water. The apparatus includes a water still for receiving water and a hot air maintained in a heat-exchanging relationship to obtain a hot water and a cold air. The apparatus also includes one or more water purification units configured to receive the hot water from the water still in which the hot water is further heated using thermal energy received from one or more thermal energy sources to obtain steam and waste matter. A water purification unit of the one or more water purification units includes a waste matter remover for removing the waste matter from the water purification unit. The water still includes a heat-exchanging unit configured to receive the steam from the one or more water purification units. The steam received at the heat-exchanging unit is condensed to obtain purified water within the heat-exchanging unit using the cold air.

Abstract: A fractionation process for producing at least two concentration fractions of a fluid including a solute, suspended or dissolved content using at least two fluidly connected evaporator units is provided. The process includes the steps of: feeding a feed fluid including a solute, suspended or dissolved content into at least a first evaporator unit; evaporating a first amount of fluid from the feed fluid in at least the first evaporator unit to produce a first concentrated fluid; feeding at least a portion of the first concentrated fluid into at least a second evaporator unit; and evaporating a second amount of fluid from the first concentrated fluid in at least the second evaporator unit to produce a second concentrated fluid.

Abstract: An apparatus for the distillation of a fluid containing at least two constituent components is disclosed. The apparatus includes a microwave energy source and a solar energy collector, both of which may be used to heat a subject fluid to a greater temperature for the purpose of distillation of same. Further, the disclosed invention combines a vacuum within the apparatus to facilitate operation and enhance the overall energy efficiency of the apparatus.

Abstract: A casing is supported above a kettle such as an electric kettle or the like and contains a condensing unit or coil connected to a source of cooling water. Steam from the kettle passes upwardly through the coil and into the casing and is condensed and collected at the base and discharged as distilled water. A feed from the heated cooling water replenishes the water supply in the kettle and may be automatic if desired.
