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 %.

A system for disinfecting an enclosed area may include a humidity sensor, and a fogging device including a portable housing, an atomizing disinfectant generator carried by the portable housing, at least one output circuit carried by the portable housing, and a processor carried by the portable housing. The processor may be configured to determine a humidity level within the enclosed area based upon the humidity sensor, operate a humidity control device via the at least one output circuit responsive to the determined humidity control level being outside of a starting humidity range, cease operating the humidity control device responsive to the humidity level being within the starting humidity range based upon the humidity sensor, and initiate a treatment cycle during which the atomizing disinfectant generator dispenses atomized disinfectant fluid into the enclosed area.

Disclosed is a mutated lactonase belonging to the phosphotriesterase-like lactonase family, which increases the susceptibility of bacteria to antimicrobial agents as compared to the use of antimicrobial agents alone.

The present disclosure relates to methods and system for disinfecting surfaces within an area by forming peracids in a reaction layer in situ on the surfaces to be disinfected. Aqueous compositions comprising peracid reactant compounds, particularly hydrogen peroxide and acetic acid, are sequentially dispersed into the area, preventing peracids from being formed until the two peracid reactant compounds contact each other on the surface to be disinfected. Additionally, aqueous compositions containing peracid reactant compounds can further comprise ethanol to both decrease the surface tension of the droplets and enhance the reactants' biocidal activity. Peracid reactant compounds can be sequentially dispersed as electrostatically-charged droplets, so that droplets of a first aqueous composition containing at least one peracid reactant compound are dispersed with a polarity opposite that of a subsequently-applied second aqueous composition containing at least one peracid reactant compound, driving formation of a peracid on the surface in situ.

The present disclosure relates to methods and system for disinfecting surfaces within a volumetric space by forming peracids in a reaction layer in situ directly on the surfaces to be disinfected. Particularly, a peroxide compound and an organic acid are sequentially dispersed into the volumetric space, preventing peracids from being formed until the two reactants contact each other on the surface to be disinfected. In some embodiments, any of the dispersed aqueous compositions can optionally be electrostatically charged. Additionally, a system for sequentially dispersing the peracid reactant compounds by electrostatic spraying is provided.

A method of disinfecting a fluid circuit of a thermal control for delivering temperature controlled fluid to at least one patient therapy device comprises the steps of providing an aqueous mixture comprising a disinfectant and circulating the aqueous mixture in the thermal control unit to disinfect the fluid circuit. The disinfectant comprises free-chlorine, a phenol, hydrogen peroxide (H.sub.2O.sub.2), or combinations thereof. If the disinfectant comprises free-chlorine, the free-chlorine is provided by a chlorinated isocyanurate (e.g. sodium dichloroisocyanurate; NaDCC). In addition, the free-chlorine is present in the aqueous mixture in an amount of at least about 100 parts per million (ppm). If the disinfectant comprises the phenol, the phenol is natural (e.g. thymol). In addition, the phenol is present in the aqueous mixture in an amount of at least about 10,000 ppm. If utilized, H.sub.2O.sub.2 is present in the aqueous mixture in an amount of at least about 5,000 ppm.

Methods of inactivating microbiological contamination described herein use a textile or membrane which can generate a contamination-inactivating amount of ozone or a reactive oxygen species. The textile or membrane includes first and second conductive layers and at least one ion conductive or porous intermediate layer positioned between the first and second conductive layers. The textile or membrane can form part of a protective face mask, for example a medical or surgical face mask. A voltage effective to generate a microbiological contamination-inactivating amount of the inactivating species is applied across the intermediate layer of the textile or membrane.
