A medium for purifying fluids containing toxic compounds can be made by a method which comprises applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier to the surface of a substrate having a high surface area and allowing the inert liquid carrier to penetrate into the substrate, wherein the inert liquid carried does not react with halogen atoms in the halogenated heterocyclic N-halamine, wherein the halogenated heterocyclic N-halamine is capable of destroying the toxic compound by oxidative action, and wherein the halogenated heterocyclic N-halamine becomes deposited on the surface of the substrate after the inert liquid carrier penetrates into the substrate.

Method for manufacturing a medium for purifying fluids containing toxic compounds

Articles can be provided with odor resistance by applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier onto the surface of the article and allowing the inert liquid carrier to penetrate into it. The N-halamine accordingly becomes deposited on the surface of the article after the inert liquid carrier penetrates into the article. This method can be used to provide odor resistance to a variety of substrates, including garbage bags. It can also be used to deposit other functional particulates onto the surface of substrates having sufficient porosity to take up the vehicle. For instance, such functional particles can be oxidants that display antimicrobial and/or enzyme inhibitory efficacy or particles having toxin interaction potentials through oxidative degradation or adsorption of toxic substances in air and/or water, such as fluoride uptake by metal oxide microparticles.

The present invention includes multifunctional compositions, methods and binding systems to provide disinfecting and deodorizing coatings for hard and soft surfaces, inorganic and organic solid surfaces and particulate media and other related substrates, including human and animal skin and skin lesions; to provide neutralizing functions for malodors generated by both human, animal and industrial fluids and solid wastes; and to provide neutralizing and degrading functions for nuisance and noxious chemicals. The present invention provides compositions and methods for producing disinfecting, oxidizing and enzyme-inhibiting fluids enabling preparation of durable, stable biocidal and deodorizing coatings and media which can be widely used for biological agent control, prevention and elimination of odors, and degradation of noxious agents susceptible to chemical oxidation, and which take forms that are inoffensive to users and offer high convenience.

A method uses anionic and cationic polymers added in, any order or simultaneously, to aqueous media for the removal of substances. The sequential addition of the two biopolymers, anionic xanthan, followed by cationic chitosan, causes the rapid formation of very large and cohesive fibrillar aggregates that may exhibit high solids to liquid ratios and that quickly settle out from the aqueous media. The aqueous media can be easily separated from the large fibrillar aggregates by settling under gravity or by filtration through a porous containment device, such as a synthetic or non-synthetic woven or non-woven fabric including a geotextile fabric or a solid containment device containing a solid mesh screen.

A water treatment composition includes a water soluble film formed into a sealed pouch. The pouch contains a composite of a phosphate removing substance, a polymer flocculant, or an enzyme, or any combination. The phosphate removing substance, the polymer flocculant, and the enzyme are bound to each other within the composite. The pouch is added to a body of water. The pouch dissolves to release the compounds and treat the water.

Water treatment composition and method of using same

A method for removing submicron colloidal particulates, such as hydrocarbons, from water. The method includes first adding a soluble, cationic polymer, such as chitosan, a salt, or solution of chitosan to water containing the submicron particulates and a halogenating agent, followed by adding a soluble, anionic polymer or anionic salt to the water. The resulting flocs are filtered to remove the submicron particulates.

A method for stabilizing and removingoocysts orcysts from water. The method comprises adding chitosan, a salt or solution of chitosan to water containingoocysts orcysts and a halogenating agent. The method may also include adding a secondary polyelectrolyte flocculant to the water. The resulting flocs are filtered to remove theoocysts orcysts.

A composition and the method for sustaining the biocidal activity of chlorinated polystyrene hydantoin beads. The method comprises supplying a continuous low level halogen concentration to the chlorinated polystyrene hydantoin beads in the water to be treated that flows in contact with the chlorinated polystyrene hydantoin beads, resulting in treated water suitable for drinking.
