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.

A filter media for oxidizing and removing soluble iron contained in an aqueous fluid comprising an amount of particulate immobilized in a substantially inert porous matrix, at least a portion of the particulate having on its surface magnesium peroxide (MgO2), the amount of peroxide on the particulate surface is sufficient to oxidize the soluble iron when the fluid is passed through the filter media, to form an insoluble iron which is captured by the media.
