A method is provided for recovering pulp fibers having little damage from a used absorbent article which includes a water permeable front sheet, a water impermeable back sheet and an absorbent body that contains pulp fibers and a superabsorbent polymer. At least one opening with a circle equivalent diameter of 5-45 mm, or 10-45 mm cut, is made in the front sheet and/or the back sheet of the used absorbent article, which is then agitated in an organic acid aqueous solution with a pH of less than or equal to 2.5, and the superabsorbent polymer is deactivated and the pulp fibers and superabsorbent polymer are discharged from the used absorbent article through the opening or cut.

An ice maker includes an ice making unit comprising an evaporator connected to a refrigeration system, an ice holding bin, a sump, a pump, a drain valve, an ozonated water source, and a controller. The controller activates the ozonated water source supplying a first volume of ozonated water to the sump, thereafter activates the pump to circulate the first volume of ozonated water from the sump to the ice making unit, once a predetermined sterilization time has been reached, the controller turns off the pump and drains the first volume of ozonated water from the sump. The controller initiates an ice making mode, and activates the ozonated water source to supply a second volume of ozonated water to the sump, thereafter activates the pump to circulate the second volume of ozonated water from the sump to the ice making unit forming ozonated ice on the evaporator, and initiates an ice harvest mode to remove the ozonated ice from the evaporator and delivers it to the ice holding bin.

Technologies for sanitizing a medical instrument with ozone are described. In particular, systems, methods, and devices for sanitizing a continuous positive airway pressure (CPAP) device are disclosed. The systems and device include 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.

A disposal system utilizing a direct injection of water for an amount of time to sufficiently sanitize a chamber of the disposal system. The disposal system includes a chamber coupled to a drain of a sink at a first end of the chamber, and to a drainpipe at a second end of the chamber. A cutting mechanism, such as a rotary cutting blade, is positioned within the chamber near a floor of the chamber. A fluid-injection unit, such as a flange attachment, coupled to the first end of the chamber and the drain of the sink, includes a plurality of nozzles for introducing a fluid in a variety of streams in different directions to reach substantially an entirety of the chamber. The flange attachment can also include a water line attachment for connecting to a water line, with an optional ozone generator upstream from the disposal system.

The present disclosure relates to a treatment tool sterilizer with a micro bubble type ozone water supply. The treatment tool sterilizer includes a sterilization tub configured to accommodate an object to be sterilized; a fresh water supply; an ozone water supply including a pressure pump configured to pressurize and transfer fresh water, an ozone generator, a mixer configured to mix fresh water and ozone, and a bubble generator connected to the mixer and configured to pass fresh water and ozone through the bubble generator so as to form micro bubbles; an ultrasonic generator; a drain; a heater mounted on the sterilization tub and configured to apply heat in the sterilization tub; and a controller configured to output a control signal.

An ice maker includes an ice making unit comprising an evaporator connected to a refrigeration system, an ice holding bin, a sump, a pump, a drain valve, an ozonated water source, and a controller. The controller activates the ozonated water source supplying a first volume of ozonated water to the sump, thereafter activates the pump to circulate the first volume of ozonated water from the sump to the ice making unit, once a predetermined sterilization time has been reached, the controller turns off the pump and drains the first volume of ozonated water from the sump. The controller initiates an ice making mode, and activates the ozonated water source to supply a second volume of ozonated water to the sump, thereafter activates the pump to circulate the second volume of ozonated water from the sump to the ice making unit forming ozonated ice on the evaporator, and initiates an ice harvest mode to remove the ozonated ice from the evaporator and delivers it to the ice holding bin.

An apparatus comprises a dispensing system and a sanitizing system. The apparatus has a dispensing mode and sanitizing mode. The dispensing system may comprise a first valve and at least one component, the at least one component having an inner surface. The first valve is opened to send a free-flowing material to the at least one component when the apparatus is in the dispensing mode. The first valve is closed when the apparatus is in the sanitizing mode. The sanitizing system comprises a processing unit having a discharge cell configured to initiate a cold plasma discharge in an air flow. A tank may be configured to receive the air flow from the discharge cell of the processing unit and expose water in the tank to the air flow for a time sufficient to provide dissolution of ozone from the air flow into the water and form ozone-containing water.

A scent elimination device 100 for removing the human scent and any other scent associated with hunters in the field. The device 100 produces ozone, which is applied directly or indirectly to the clothing, equipment and body 300 while the hunter is in the field 200 and/or prior to or after the hunt. The method can also be used by fishermen to eliminate fish odor.

Systems and methods for dissolving ozone gas in a liquid. An embodiment can comprise a tank having an upper region, a lower region, and a discharge outlet, all disposed in a specified geometry. A pump can be coupled with a liquid inlet in order to receive a liquid therefrom and to deliver the liquid via a pipe to the upper region of the tank. The pump can be coupled with the lower region of the tank in order to receive the liquid from the tank and to recirculate the liquid to the upper region of the tank. The apparatus can include an ozone inlet to receive ozone into the tank. The ozone inlet can comprise a venturi inlet disposed on the pipe downstream of the pump. The liquid can be released from the tank and depressurized, thereby providing for the ozone to emerge from the liquid as gas bubbles. The released liquid can be selected for a two-stage gas and aqueous cleaning process.
