A method of inactivating an enveloped ssRNA virus, such as SARS-CoV-2. The method involves contacting the enveloped ssRNA virus with an antiviral polyelectrolyte compound and/or a conjugated aromatic compound effective to inactivate the virus. The disclosure also provides a method of reducing the period of viability of enveloped ssRNA virus, such as SARS-CoV-2, on personal protective equipment, in air, in water, and/or on surfaces that have come into contact with the virus.

A device for purifying drinking water in multiple stages by combining orthogonal purification technologies in one module is described, where the device comprises a housing, a water inlet opening, a water outlet opening, a hollow cylinder which is filled with activated carbon, and a hollow cylinder with a semipermeable wall, wherein the hollow cylinder contains a chelating bactericidal gel or a chelating and bactericidal gel for removing heavy metals or bacteria or for removing heavy metals and bacteria.

A tent comprising an exposed surface and an antimicrobial substance applied to the exposed surface. The tent can further include an interior. The exposed surface can be disposed within the interior. The tent can include a fabric. The fabric can provide the exposed surface. The tent can be a medical center. The antimicrobial substance can be a silane quaternary ammonium ion or salt thereof. The silane quaternary ammonium ion can be one or more of: 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium ion, 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, and 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride.

An object is to provide an excrement treatment agent, which can suppress not only the odor of feces but also the ammonia odor in various environments. An excrement treatment agent, comprising limonite, lignin and bentonite, wherein, when further comprising slaked lime, the amount of the slaked lime is 10 mass % or less.

Disclosed is a method and apparatus for providing polyiodide resin-enhanced personal protective equipment (PPE) including but not limited to face masks, gloves, gowns and respirators. The disclosed method comprises the application of a polyiodinated ink polymer in or on one or more targeted surfaces of PPE to create a molecular sub-microscopic protective barrier between the equipment and the user. The disclosed system provides a PPE device capable of direct contact kill of organisms. In addition, the system provides for a sustained kill of organisms for up to 96 hours. The resultant PPE device is broadly effective against viral, bacterial, fungicidal and other microbial agents.

The invention provides a unit operation formed by a device and its use for continuous virus inactivation of a continuous flow of a process fluid. The unit operation formed by a device comprises a single inlet at one end and an outlet at the opposite end and at least one HFI, characterized in that the HFI further comprises at least one installation.

Methods include producing a gelled sanitizer composition, including preparing a hydrating fluid composition including water and one or more of alcohol and peroxide; preparing a hydratable additive; and combining the hydrating fluid composition and the hydratable additive to produce a gelled composition. Methods also include flowing a hydrating liquid composition in an extensional flow regime through an elongated passageway of an extender, wherein the hydrating liquid composition includes water and a C2-C10 solvent, and a flow rate of the hydrating liquid composition and a diameter of the elongated passageway are sufficient to achieve a Reynolds number of 20,000 or greater; and adding a hydratable additive to the hydrating liquid composition in the elongated passageway to produce a mixture comprising the hydratable additive that is at least partially hydrated.
