Abstract:
A method for removing at least one of an odor component and a noxious component from an atmospheric effluent, the method comprising:combining a solution comprising a predetermined concentration of hydrogen peroxide and a solution comprising a predetermined concentration of ferrous sulfate at a feed ratio within a range of about 1:1 to about 100:1, wherein said feed ratio is defined by weight and based on a 50% by weight hydrogen peroxide solution and a 38% by weight ferrous sulfate solution, to form an aqueous hydrogen peroxide composition; contacting an atmospheric effluent containing at least one of an odor component and a noxious component with said aqueous hydrogen peroxide composition, wherein said ferrous sulfate is at a sufficient concentration to catalyze the decomposition of said hydrogen peroxide to predominantly produce hydroxyl free radicals; and oxidizing at least one of said odor component and said noxious component in said atmospheric effluent to a substantially non-odor-offensive, environmentally acceptable by-product, said oxidation producing a liquid effluent containing at least said by-product and said aqueous hydrogen peroxide composition, and an exhaust effluent having reduced amounts of at least said odor component and said noxious component.
