Claims
- 1. A fluid cycling cleaning system, including:
- a reservoir, and an aqueous surface cleaning composition contained in the reservoir, said cleaning composition consisting essentially of water, and from about 10 ppm to about 200 ppm by weight of a surfactant component resistant to interacting with ozone and selected from the group consisting essentially of: low foaming anionic surfactants; and ethylene oxide, propylene oxide block copolymers having HLB values of at most 7:
- a fluid dispensing conduit in fluid communication with the reservoir for conveying the cleaning composition from within the reservoir to an application area outside of the reservoir, and a fluid recovery conduit for recovering the cleaning composition from the application area; wherein the reservoir, the fluid dispensing conduit and the fluid recovery conduit cooperate to provide a fluid pathway for the cleaning composition;
- an ozone source, fluid coupled to the fluid pathway, for introducing ozone into the cleaning composition, whereby at least some of the ozone is dissolved into the cleaning composition; and
- an applicator fluid-coupled to the dispensing conduit for applying the cleaning composition, with ozone dissolved therein, to the application area.
- 2. The system of claim 1 wherein:
- said ozone source is adapted to introduce the ozone at a rate sufficient to maintain the ozone at a concentration within the range of about 0.01 ppm to about 4 ppm of the cleaning composition, by weight.
- 3. The system of claim 1 wherein:
- said surfactant component consists essentially of at least one of the following constituents: sodium octyl sulfate; sodium octyl sulfonate; sodium ethyl hexyl sulfate; sodium mono and didecyl disulfonated diphenyl; sodium mono and didodecyl disulfonated diphenyl; and said ethylene oxide, propylene oxide block copolymers.
- 4. The system of claim 3 wherein:
- said surfactant component consists essentially of sodium octyl sulfate from about 10 ppm to about 100 ppm, by weight.
- 5. The system of claim 4 wherein:
- the surfactant includes ozone at a concentration in the range of about 0.05-0.5 ppm, by weight.
- 6. The system of claim 1 wherein:
- said surfactant is incorporated at a concentration ranging from about 10 ppm to about 100 ppm, by weight.
- 7. The system of claim 6 wherein:
- said concentration of the surfactant is in a range from about 10 ppm to about 30 ppm, by weight.
- 8. The system of claim 1 wherein:
- the surfactant includes ozone at a concentration of about 0.01 ppm to about 4 ppm.
- 9. The system of claim 8 wherein:
- the concentration of ozone is from about 0.05 ppm to about 0.05 ppm.
- 10. The system of claim 1 wherein:
- the surfactant further includes an alkalinity enhancing constituent stable in the presence of ozone.
- 11. The system of claim 10 wherein:
- the alkalinity enhancing constituent consists essentially of at least one of the following: sodium carbonate, sodium bicarbonate, and sodium sesqui carbonate.
- 12. The system of claim 1 wherein:
- the surfactant further includes a water conditioner having substantially no ozone demand.
- 13. The system of claim 12 wherein:
- said water conditioner consists essentially of at least one of the following: citric acid, tetrapotassium pyrophosphate, and sodium hexametaphosphate.
