Abstract: A portable, potable water recovery and dispensing system for use inside a home, office or, in an emergency situation, unprotected outside a building, comprising: (a) a wheeled, finished, furniture-type housing enclosure having four vertical side panels with handling grips on at least two of the panels, a top panel and a bottom panel, the housing provided with tightly-sealed seams between the panels and insect-preventive openings for all hinged or lift-out service-access sub-panels, through-wall connections and pass-through openings, including openings for mechanical controls, tubes, valves, electronic cables, power cables and air-transfer ports, (b) edge-sealed inlet and exhaust air-transfer ports of area covered with insect-resistant screens, (c) ducted particle-generating means sealingly connected downstream of the inlet air-transfer port provided with at least one of: (a) electrodes for generating charged particles and ions or (b) one or more radioisotope sources for emitting charged particles, the particle-generating means sealingly connected to the air inlet port, (d). filtration means adapted to remove and trap particulates of diameter larger than 1-10 micrometers dispersed in ambient air, the particle-generating means sealingly connected upstream of the filtration means, (e) the exhaust air transfer port adapted to mount an optional charged-particle generator inside the housing whereby a physiologically-safe level of charged particles and ions is added to the air being discharged, (f) internal, ducted, electric, rotary air-circulation means of controllable, variable flow volume of ambient air sealingly connected downstream of the filtration means, (g) an enclosed cooling means, heat absorber, sealingly connected downstream to the exhaust port and upstream to the air-circulation means, containing a plurality of cooled, spaced-apart, extended-area, dew-forming surfaces sealingly connected to receive particle-free air from the air-circulation means adapted to cool the boundary-lay air adjacent to the dew-forming surfaces to a temperature at least 1-10 DEG C below the equilibrium dewpoint of the inlet air stream, thereby forming liquid-water on the dew-forming surfaces, the surfaces being formed and positioned for gravity flow of the liquid water into a removably-attached, enclosed dripoff collection vessel, (h) enclosed fluid-reservoir means of volume in the range 1-10 liters, sealingly connected to the dripoff collection vessel of the heat absorber, the reservoir being formed using welding techniques and materials appropriate for storage vessels for high-purity drinking water and fitted with a outlet connection whereby at least 90% of the water held therein can be pumped out, (i) bacteriostat loop means sealingly connected to the fluid reservoir and fitted with a closed-loop, ecirculation channel and pump whereby water in the reservoir is pumped at a predetermined flow rate through an activated-carbon porous 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, and j. delivery channel sealingly connected to the closed-loop channel and extending through one of the vertical panels to an external dispensing valve.
