Various implementations include a fluid treatment device. The device includes an outer tube, an inner tube, a plurality of blades, and a media. The outer tube includes an inner surface. The inner tube is coaxially disposed within the outer tube. An outer surface of the inner tube and the inner surface of the outer tube define an annulus that axially extends between the ends of the inner tube. The plurality of blades is disposed within the annulus. The plurality of blades is configured to alter a component of a flow direction of fluid flowing over the blades in a circumferential direction and/or a radial direction. The media is disposed within the inner tube. The inner tube defines a plurality of perforations extending between its outer surface and inner surface. The annulus defines an entire flow path of fluid flowing between the outer tube and the inner tube.

The present disclosure relates to a method for treating an object with chlorine dioxide gas, comprising contacting the object with chlorine dioxide gas while exposing the object to less than 1000 lux of light. The disclosed method minimizes chlorine containing residue on the surface of the object. The object can be a raw agricultural commodity (RAC) such as a raw fruit or vegetable.

Methods for treating an object with chlorine dioxide

The present disclosure relates to a mixture for producing chlorine dioxide gas provided in an enclosure comprising an impregnate comprising a chlorine dioxide precursor impregnated in a porous carrier and a proton-generating species, wherein the impregnate and proton-generating species are intermixed to produce a stable mixture and the mixture is provided in an enclosure. The present disclosure also relates to methods for producing chlorine dioxide gas.

The invention is a method for attracting mosquitoes by producing a volatilized acid by combining an acid precursor with water to produce the humidified vapor acid attractant, preferably hydrogen chloride. The humidified volatilized acid can be further combined with carbon dioxide, or carbon dioxide can be simultaneously produced to attract mosquitoes. The acid precursor can be a hydrate of ferric chloride, such as ferric chloride hexahydrate. The acid precursor can be impregnated in a carrier, and can be combined with water through exposure to water vapor in the atmosphere, the intentional addition of water, or water produced by a chemical reaction.

A self-contained generator/fumigator and delivery system is described herein that provides for sealed containment to store, isolate and protect two or more solid and/or liquid reactants in separate chambers. Upon activation, the container facilitates robust mixing of the reactants, the containment thereof and allows the release of a pre-determined amount of gaseous products, e.g., chlorine dioxide, carbon dioxide and others, into a targeted volume of water, air or other solution.

Container for mixing

The invention is a method and composition for producing carbon dioxide that is based on the reaction or activation of at least one carbon-containing compound with protons. The carbon-containing compound can be in the form of a powder, an impregnated carrier (e.g. zeolite crystals) or an aqueous solution and is preferably selected from the group consisting of carbonates, bicarbonates or sesquicarbonates. The protons are preferably provided by a proton-generating species such as an acid or metal salt. The method and composition can further include a water-retaining substance and/or a chlorine dioxide-producing compound in accordance with the invention.
