The present invention relates to an aqueous ozone floor disinfection system. A floor cleaning machine traverses a floor surface entering a pre-hygienic zone prior to cleaning, cleaning within a midst-hygienic zone for a cleaning period, and moving away from the midst-hygienic zone creating a post-hygienic zone. An aqueous ozone generator receives water and generates an ozonated concentrate liquid. A post-hygienic mixer ratiometrically blends the ozonated concentrate liquid and water to form a post-hygienic ozone disinfection solution having a predetermined post-hygienic ozone treatment concentration. A post-hygienic nozzle spray of the post-hygienic ozone disinfection solution onto the post-hygienic zone portion of the floor surface for at least a post-hygienic treatment time absent agitation or removal by the floor cleaning machine improving disinfection of the floor surface. The service life of the aqueous ozone generator can be tracked and the disinfected floor surface can be GPS geofenced.

The present invention provides a method for producing electrolyzed water composition for use in cleaning and disinfecting of an object. The method comprises preparing an electrolyte solution comprising water, at least one carbonate salt selected from: alkali metal carbonate salts, and at least one chloride salt selected from: alkali metal chloride salts and/or alkali earth metal chloride salts.

An object of the present invention is to provide an ozone water having enhanced storage stability and a method for producing the ozone water. An ozone water of the present invention as a means for resolution is produced by dissolving 0.1 M to 1 mM of an organic iron compound and 1 to 300 mM of an inorganic salt in a water with ozone-microbubbles generated using an ozone gas at a concentration of 1 to 300 g/Nm.sup.3. The half-life of ozone of the ozone water of the present invention is 3 days or longer, for example, when the water filled in an airtight container under atmospheric pressure is stored under a temperature condition of 40 C.

Systems and methods for sanitization of surfaces, such as hands, are provided. In general, the described techniques utilize a system including a housing having an active agent receptacle in fluid communication with at least one nozzle, and an air pump in fluid communication with the at least one nozzle. The system also includes a control module configured to control the delivery of an active agent as an aerosol spray through the at least one nozzle in a delivery dose. The delivery dose is expelled onto the surface as a thin uniform layer and dried such that the entire surface sanitization process is completed in less than or equal to 5 seconds. The active agent receptacle can be configured to receive a removable and replaceable cartridge carrying the active agent.

A method for dynamic dosing of disinfectant solution in a medical device reprocessing system includes calculating a volume of an initial dose of concentrated disinfectant solution for dilution to make a first in-use disinfectant solution. The initial dose of concentrated disinfectant solution is diluted with diluting fluid to make the first in-use disinfectant solution comprising a target concentration of disinfectant agent. The first in-use disinfectant solution is applied to a medical device. A concentration of the disinfectant agent in the first in-use disinfectant solution is then calculated. The actual concentration of the disinfectant agent in the concentrated disinfectant solution is then calculated based upon the concentration of disinfectant agent in the first in-use disinfectant solution. It is then determined whether a volume of a second dose of concentrated disinfectant solution is increased or about the same as the volume of the initial dose to make a second in-use disinfectant solution.
