This disclosure relates to a method for sanitizing a space. The method includes applying a composition containing triethylene glycol into a space containing a pathogen (e.g., a Staphylococcus, a Pseudomonas, a Listeria, Salmonella, Klebsiella, a Mycobacterium, a mold, or a spore) in an amount effective to inactivate the pathogen.

A method for cleaning medical equipment by scrubbing the equipment with an open-cell melamine-formaldehyde foam comprising an antibacterial active composition, and wherein the open-cell melamine-formaldehyde foam is prepared from a melamine-formaldehyde precondensate, wherein the molar ratio melamine to formaldehyde of the melamine-formaldehyde precondensate is smaller than 0.5.

To provide a sterilizing liquid and a method of producing the same that have no restrictions on application methods and usage and can be widely used for sterilization, a sterilizing liquid including water containing reactive oxygen species and a nanoparticle catalyst in a stationary state is produced by causing cavitation in water having a conductivity of 2000 μS/cm or less and COD of 2000 ppm or less while causing the water to flow by a stirrer 2, and causing generation of plasma by a plasma generation mechanism 3 in which a pulse voltage is applied across electrodes 31 in the water including air bubbles mainly containing water vapor generated by the cavitation.

Disclosed is a method for disinfecting and cleaning to prevent contamination of a passenger vehicle, characterized in that it includes the following operations: —installing at least one filter and condenser in the ventilation circuit; creating a swirling vortex of a disinfectant liquid by a gas referred to as a driving gas; spraying the swirling mixture created onto the clothing and luggage of passengers before they enter the passenger compartment; and spraying the mixture created onto the solid surfaces and/or into the air of the passenger compartment to be disinfected. Also disclosed is a device for implementing the method.

The disclosure relates to a microbicidal composition with excellent action of limiting a decrease in durability of synthetic adhesives as well as high microbicidal action. The microbicidal composition contains 0.03 to less than 1.0 mass % of peracetic acid, 0.045 to less than 1.5 mass % of hydrogen peroxide, and 0.036 mass % or more of glycine.

A sanitizing spray system includes a Nitrogen generation system that produces Nitrogen used as a carrier gas source for spraying an alcohol-based disinfecting and sanitizing composition without flashing.

The present invention achieves a decontamination effect with a proper amount of hydrogen peroxide mist supplied to a room to be decontaminated by further refining such hydrogen peroxide mist supplied to the room for dispersion/diffusion, and reducing the duration of operations such as aeration to increase efficiency of decontamination.

The decontamination system includes a mist generation means, a mist discharge port, and a mist dispersion/diffusion means. The mist generation means converts a decontamination liquid into a mist to generate a mist for decontamination. The mist discharge port is opened at an upper portion on an internal side wall surface of the room to discharge a such mist into the inside of the room. The mist dispersion/diffusion means generates sound flows by an ultrasound in the vertical direction from a plate surface of a vibration plate provided adjacent to a lower portion of the mist discharge port on the internal side wall surface of the room or adjacent to a lower portion on a side surface in a mist discharge direction. The mist is pressed by acoustic radiation pressure backward or laterally in intermittent operation or stronger/weaker operation of the system.

The present technology relates to a novel sanitization method for chromatography media and supporting equipment comprising treatment with a sanitization/sterilization solution comprising acetic acid and hexylene glycol.

The present disclosure provides decontamination system that includes a decontamination chamber for sealably holding one or more items for decontamination. The system also includes a decontamination unit comprising: a controllable air heater and humidity control unit to controllably heat an ambient air source and to control a temperature and humidity of air within a decontamination chamber; a controllable vaporizer unit to controllably vaporize one or more decontamination agents by combining the controllably heated ambient air with the one or more decontamination agents; and controller circuitry to control a controllable air heater and humidity control unit to heat the ambient air to a selected level, and to maintain a selected heat and humidity within the decontamination chamber, and to control the controllable vaporizer unit to provide a selected flow rate of the one or more decontamination agents into the decontamination chamber.

In a method for controlling unpleasant odors in discharge air from containers, rooms or plants in which strong smelling substances such as feces, waste or highly odorous foods are stored or processed, a fluid is introduced into the discharge air in a finely distributed form, which physically and/or chemically neutralizes the odor of the substances contained in the discharge air. The fluid is a 0.1% to 8% aqueous solution of an active substance concentrate which is 55-65 wt.-% triethylcitrate, 17.5 to 22.5 wt.-% 1,2 propanediol and 17.5 to 22 wt.- % di-propylene glycol-methylether. Alternatively, the fluid can also be a mixture of a suitable propellant gas mixture and the active substance concentrate specified above.
