Abstract:
A portable, potable-water recovery system for producing and dispensing water comprising:a portable enclosure provided with an inlet port, an outlet port and air-circulation means for circulating ambient air from said inlet port to said outlet port and water-condensing means within said enclosure,characterized in thata. at least one air filtration means adapted to remove and trap particulates of diameter larger than 1-100 micrometers dispersed in ambient air is sealingly connected upstream of said air circulation means,b. said air-circulation means comprising an internal, ducted, electric, rotary air-circulation means of controllable, variable flow volume of ambient air sealingly connected downstream of said at least one filtration means,c. water condensing means comprising an enclosed cooler having dew-forming surfaces sealingly connected downstream to said filtration means and upstream to said air-circulation means, said dew-forming surfaces adapted to cool the boundary-layer air adjacent to said dew-forming surfaces to a temperature at least 1-10 deg. C below the equilibrium dew point of the inlet air stream, thereby forming liquid-water on said dew-forming surfaces, said surfaces being formed and positioned for gravity flow of said liquid water into a combined condensate collector and storage reservoir,d. said combined condensate collector and storage reservoir of material appropriate for storage of high-purity drinking water and fitted with an outlet connection whereby most of the water held therein can be withdrawn,e. a discharge line connected to said combined condensate collector and storage reservoir whereby water in said combined condensate collector and storage reservoir is pumped at a predetermined flow rate through a water filter meeting NSF 53 standards for removing volatile organic compounds, said water filter connected in series with a bacteriostat where the water is exposed to radiation of sufficient energy and appropriate wavelength to kill adventitious bacteria and viruses,f. said discharge line sealingly connected to said combined condensate collector and storage reservoir extending through said housing for external dispensing of purified water from said combined condensate collector and storage reservoir,g. means within said enclosure for sequencing control operations and monitoring and/or visually displaying integrity of system components therein.
