A portable, potable-water generator for producing high-purity liquid water by condensation of dew from ambient air. The generator employs filtration subsystems to remove particulates and acrosols from the incoming air. An enclosed heat absorber cools the filtered air to its dew point and collects droplets of condensate into a closed system. The collected dew is further continually treated in a bacteriostat loop to destroy adventitious living organisms and to filter out undesirable and dangerous contaminants. All the subsystems are fail safe-interlocked to disable the generator immediately and prevent delivery of water if any one of them stops functioning within predetermined safe limits.

[ What is claimed is:] [1.] 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. 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 filtration means,c. water condensing means comprising an enclosed first cooling means sealingly connected downstream to said filter port and upstream to said air-circulation means including 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 enclosed drip off collection vessel,d. enclosed fluid-reservoir sealingly connected to said drip off collection vessel of material appropriate for storage of high-purity drinking water and fitted with a outlet connection whereby most of the water held therein can be withdrawn,e. bacteriostat loop means sealingly connected to said fluid reservoir and comprising a closed-loop, recirculation channel and pump whereby water in said reservoir is pumped at a predetermined flow rate through a disposable activated-carbon porous VOC filter-absorber connected in series with a UV treatment zone where it is continually exposed to radiation of sufficient energy and appropriate wavelength to kill adventitious bacteria and viruses,f. a first delivery channel sealingly connected to said recirculation channel, extending through said enclosure and terminated with a valve for external dispensing of purified water from said reservoir, andg. means within said enclosure for sequencing control operations, monitoring integrity and indicating proper operation of system components therein.
