Filter media, method for oxidizing and removing soluble iron, method for removing and inactivating microorganisms, and particulate filter aid

Abstract: A filter media is provided which comprises an amount of particulate immobilized in a substantially inert porous matrix. A least a portion of the particulate surface has thereon a divalent metal peroxide. The metal peroxide is magnesium peroxide or calcium peroxide, preferably magnesium peroxide. The filter media is preferably used for oxidizing and removing soluble iron and manganese from an aqueous fluid. The filter may also be used for removing and inactivating microorganisms from fluids, e.g. aqueous fluids. Particulate filter aid having coated or adsorbed on the surface the aforementioned metal peroxide may be used as the particulate in the filter media, as well as the metal peroxide in particulate form.
