an atomizing tray;
an atomizing device within the atomizing tray, the atomizing device being operable to produce a fog comprising liquid droplets having diameters between about 0.5 micron and about 20 microns;
a tank for holding a quantity of a disinfecting composition;
a recirculating pump for transferring the disinfecting composition from the tank to the atomizing tray and maintaining a depth of the disinfecting composition within the atomizing tray;
at least one port for discharging the fog into the area or enclosed space; and
an in-line dehumidifying device.
2. The apparatus of claim 1 , wherein the atomizing device for producing the fog includes a piezo disc nebulizer operable at a frequency between about 1.50 MHz and about 2.50 MHz.
3. The apparatus of claim 1 , wherein the atomizing device for producing the fog includes a high-speed rotary disc atomizer.
4. The apparatus of claim 1 , wherein the atomizing device for producing the fog includes at least one device selected from a group consisting of: small orifice misting nozzles, impingement misting nozzles, and air atomizing nozzles.
5. The apparatus of claim 1 , further comprising:
a device for inducing an electrical charge in at least a portion of the liquid droplets.
6. The apparatus of claim 1 , further comprising:
a filtering device for removing odor from an atmosphere.
7. The apparatus of claim 6 , wherein the filtering device includes activated carbon.
8. A disinfecting system comprising:
a tank containing a quantity of a disinfecting composition; and
an atomizing tray;
a recirculating pump for transferring the disinfecting composition from the tank to the atomizing tray and maintaining a depth of the disinfecting composition within the atomizing tray;
an atomizing device within the atomizing tray, the atomizing device being operable to produce a fog of the disinfecting composition, the fog comprising liquid droplets having diameters between about 0.5 micron and about 20 microns, and the device comprising:
a high-speed rotary disc atomizer;
at least one port for discharging the fog into the area or enclosed space; and
an in-line dehumidifying device.
9. The disinfecting system of claim 8 , wherein the disinfecting composition includes at least one of the following: hypochlorous acid, hypochlorite ion, sodium hypochlorite, chlorine, silver, hydrogen peroxide, ethaneperoxoic acid, tetraacetylethylenediamine, caprylic acid, alkyl dimethyl benzyl ammonium chloride, didecyl dimethyl ammonium chloride, triethylene glycol, peroxyacetic acid, isopropyl alcohol, octanaminium, octyl decyl dimethyl ammonium chloride, benzyl-p-chlorophenol, phenylphenol, dimethyl benzyl ammonium saccharinate, sodium dichloroisocyanurate dehydrate, or sodium chlorite.
10. The disinfecting system of claim 8 , wherein the disinfecting composition comprises hypochlorous acid and hypochlorite ion.
11. The disinfecting system of claim 8 , wherein the disinfecting composition comprises hydrogen peroxide and peroxyacetic acid.
12. The disinfecting system of claim 8 , wherein the atomizing device for producing the fog includes a piezo disc nebulizer operable at a frequency between about 1.50 MHz and about 2.50 MHz.
13. The disinfecting system of claim 8 , further comprising:
a device for inducing an electrical charge in at least a portion of the liquid droplets.
14. A disinfecting apparatus comprising:
at least one rotary disc atomizer; and
a port for discharging an atomized disinfecting composition,
wherein the at least one rotary disc atomizer includes a multi-head high-speed rotary disc nebulizer operable to produce droplets of disinfecting composition having a diameter between about 2 microns and about 20 microns.
15. The disinfecting apparatus of claim 14 , wherein the at least one rotary disc atomizer is operable to produce droplets of disinfecting composition having a diameter between about 2 microns and about 5 microns.
16. The disinfecting apparatus of claim 14 , further comprising:
a tank for containing the disinfecting composition.
17. A disinfecting apparatus comprising:
at least one rotary disc atomizer;
a port for discharging an atomized disinfecting composition;
a dehumidifying device; and
at least one filter having low-micron moisture droplet air-flow vanes.
18. The disinfecting apparatus of claim 17 , wherein the at least one filter includes an impingement-type separator.
