A method for decontaminating a low-temperature article to accomplish decontaminating a surface of the such article, and to reduce duration of operations to increase efficiency of decontamination, and a pass box used in such method.

The method includes an applying step of applying a decontamination agent to external surfaces of the article, and a drying step of irradiating the article with agent thereon with ultrasonic waves and drying the surface. In the applying step, a gas, fog or mist of the decontamination agent is supplied to a target surface to form a condensed film of the agent on the target surface. In the drying step, dry air is supplied to the target surface.

Peroxyformic acid compositions for treatment and removal of biofilm growth and mineral deposits on membranes for energy services applications are disclosed. In particular, peroxyformic acid compositions are generated in situ or on site generation for the reduction and prevention, of biofilms and the mitigation of mineral buildup on the membranes. The compositions according to the invention are compatible with the membranes under application of use conditions.

The invention provides a percarboxylic acid concentration-determining device capable of determining the concentration of percarboxylic acid contained in an aqueous solution for chemical sterilization or disinfection that contains a percarboxylic acid as an active ingredient; and an indicator solution for use in preparing the device. The indicator solution contains a starch, an iodide, a thiosulfate, a water-soluble organic solvent, and water, with the starch, the iodide, the thiosulfate, and the water-soluble organic solvent being present in the following proportions, based on the total amount taken as 100 mass %: (a) starch: 0.01 to 5 mass %; (b) iodide: 0.01 to 5 mass %; (c) thiosulfate: 0.01 to 10 mass %; and (d) water-soluble organic solvent: 0.1 to 40 mass %, wherein the total amount of (a), (b), and (c) is greater than 0.6 mass %.

An antimicrobial composition includes peracetic acid and witch hazel extract. The peracetic acid can be formed by combining and reacting the acetic acid and hydrogen peroxide, for example at the point of use. Alternatively, the peracetic acid may be formed separately and mixed with the witch hazel extract prior to use. The resulting peracetic acid and hydrogen peroxide are, thus, combined with the witch hazel extract prior to use. The combination of peracetic acid, hydrogen peroxide and witch hazel extract may be applied as an antimicrobial. The antimicrobial composition may be applied topically to various organs (e.g., skin, nose, ears, mouth, throat, urethra, urinary bladder, gastrointestinal organs) or instilled through an indwelling urinary catheter or applied or inserted as a topical additive or coating to devices or other organ surfaces or other medical devices, or on the skin of the body or surfaces of inanimate objects.

A preform is sterilized by a preform sterilizer. The preform is blow-molded by a blow-molding device to manufacture a container. Next, the container is filled with a culture medium by a filling device without sterilizing the container by a container sterilizer, and the container is plugged by a plugging device. Thereafter, it is verified how much microorganism survive or propagate in the culture medium in the container. A degree of sterilization in the container sterilizer is adjusted on the basis of a verification result.

Provided herein is a system for disinfection and deactivation of contaminants, and more particularly to a self-contained compressed air disinfection system and method to deactivate pathogens on all surfaces and/or in the air of the targeted interior space comprising reusable compressed air cylinders and single-or multi dose containers of disinfectant or decontaminant.

An antimicrobial composition contains hydrogen peroxide, an organic sulfonic acid, and a peroxide adjuvant. The peroxide adjuvant is a small molecule organic acid, such as formic acid. The antimicrobial composition is very effective at sanitizing surfaces in all different types of fields, such as in the healthcare industry. The antimicrobial composition is well suited for controlling C.difficile.

A self-disinfecting coating (1) for surfaces: is provided that includes a base matrix (2) and a loading solution (3), the matrix (2) in turn includes a gel base (10) and a gel fluid (7), and the loading solution (3) comprises an active disinfectant ingredient (4), in such a way that the base matrix (2) is able to absorb and retain the active ingredient (4) while maintaining, on the free surface of the coating (1), a sufficient concentration of active ingredient (4), thus maintaining the surface disinfected. The gel base (10) may include a protein of collagen, albumin or elastin and glycerine as the plasticising agent (6). The loading solution (3) may include elemental iodine as an active ingredient (4) and ethanol as the loading solvent (8). The self-disinfecting coating (1) may include a base substrate (11) that includes therein the base matrix (2) and loading solution (3).

A cleaning, sanitizing or disinfecting scrubbing device includes a body, a non-thermal plasma generator and damp wipe. Generated plasma activates fluid in the wipe. The device may include spacer posts between the body and wipe and a conductive mesh between the body and wipe or embedded in the wipe. Another embodiment includes a reservoir for holding a water-based fluid, a fluid delivery element connected to the reservoir by a tube through which the fluid can flow and a non-thermal plasma generator. The non-thermal plasma generator activates the fluid. In one embodiment the scrubbing device is a mitt. In another embodiment the scrubbing device is a glove.

Methods and systems for on-site, continuous generation of peracid chemistry, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions, are disclosed. In particular, an adjustable biocide formulator or generator system is designed for on-site generation of peroxycarboxylic acids and peroxycarboxylic acid forming compositions from sugar esters. Methods of using the in situ generated peroxycarboxylic acids and peroxycarboxylic acid forming compositions are also disclosed.
