Technologies (e.g., devices, systems and methods) for sanitizing mist humidifiers are described. In some embodiments, the technologies include a sanitization gas system and a connector unit. The connector unit is configured to install into an opening in the mist humidifier that is used in operation to release mist for humidification purposes. The connector unit includes an inlet passageway for supplying sanitizing gas (e.g., ozone) into the humidifier, and an exhaust system for removing sanitizing gas from the reservoir.

Disclosed are methods for continuous production of ozone strong water, the methods comprising the steps of injecting an acidification agent into a pressurized feed water to maintain a pH value of the pressurized feed water below 7, diffusing a two-phase mixture of O.sub.2-O.sub.3 gas) and recirculated water into a body of acidic pressurized water to dissolve ozone into the acidic pressurized water. The disclosed methods include simultaneously maintaining a start-up mode in an upper portion of the dissolution column that favors high efficiency of ozone mass transfer into the acidic pressurized water and a steady state mode in a lower portion of the dissolution column that favors a high concentration of dissolved ozone in the acidic pressurized water coexistent in the body of the acidic pressurized water, wherein an ozone concentration gradient is formed along a height of the body of the acidic pressurized water.

Disclosed are systems for continuous production of ozone strong water, the systems comprising an injection device that injects an acidification agent into a pressurized feed liquid, a diffuser device that injects ozone into a body of the acidic pressurized feed water, and injection nozzles each controlled by a valve that adjust a flow rate of the ozone strong water discharged from a dissolution column to match a flow rate of the acidic pressurized feed water fed to the dissolution column, thereby maintaining a start-up mode in an upper portion of the dissolution column that favors a high efficiency of ozone mass transfer and a steady-state mode in a lower portion of the dissolution column that favors a high dissolved ozone concentration coexistent in the body of the acidic pressurized liquid, wherein a concentration gradient of dissolved ozone is formed along a height of the body of the acidic pressurized liquid.

Technologies (e.g., devices, systems and methods) for sanitizing reservoirs are described. In some embodiments, the technologies include a sanitization gas system and a connector unit or a hole in the reservoir wall, configured to connect a supply line to the reservoir. The connector unit may include an inlet passageway for supplying sanitizing gas (e.g., ozone) into the reservoir.

A method and apparatus for significantly extending the shelf life of an inert gas infused fluid. Air that has been subjected to a high electrical potential corona and then mixed with a fluid in a constant differential pressure venturi is delivered to an improved container apparatus wherein an inert gas is infused into the fluid such that the resultant stabilized fluid demonstrates significantly improved usable life. Alternatively, an additive may be combined to provide application specific characteristics. The combination of the method and apparatus, taken together, provide substantially increased shelf life of an inert gas infused fluid.

The present invention is generally related to a device and method for sanitizing a medical instrument with ozone, in particular the invention relates to a system, method and a device for sanitizing a continuous positive airway pressure (CPAP) device. The device has an ozone compartment, an ozone operating system and one or more ozone distribution lines that distribute ozone to a continuous positive airway pressure device. The device may further include a heater adapter unit to connect heating systems in CPAP devices while distributing ozone to sanitize the CPAP device in accordance with the present invention.

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.

Technologies (e.g., devices, systems and methods) for sanitizing reservoirs are described. In some embodiments, the technologies include a sanitization gas system and a connector unit or a hole in the reservoir wall, configured to connect a supply line to the reservoir.

The purpose of the present invention is to provide a method which is for producing pulp fibers for cellulose nanofiberization from pulp fibers of used sanitary products, and which can produce pulp fibers for cellulose nanofiberization that have low lignin content and a low distribution thereof and that have excellent cellulose nanofiberization properties. This method is described below. The method is characterized by involving: a step for supplying, from a mixed solution supply port (32) to a treatment tank (31), a mixed solution (51) which contains superabsorbent polymers and pulp fibers derived from used sanitary products; a step for supplying an ozone-containing gas (53) from an ozone-containing gas supply port (43) to a treatment solution (52) inside of the treatment tank (31); a step in which, by raising the ozone-containing gas (53) while lowering the superabsorbent polymers and pulp fibers in the treatment tank (31), the ozone-containing gas (53) is brought into contact with the superabsorbent polymers and the pulp fibers, and pulp fibers for cellulose nanofiberization are formed from the pulp fibers; and a step for discharging the treatment solution (52) from a treatment solution discharge port (33), wherein the pulp fibers for cellulose nanofiberization have a lignin content of less than or equal to 0.1 mass %.
