FILTER MEDIA, METHOD FOR OXIDIZING AND REMOVING SOLUBLE IRON, METHOD FOR REMOVING AND INACTIVATING MICROORGANISMS AND PARTICULATE FILTER AID

摘要

ABSTRACTA filter media is provided which comprises an amount ofparticulate immobilized in a substantially inert porous matrix. Atleast a portion of the particulate surface has thereon a divalentmetal peroxide. The metal peroxide is magnesium peroxide orcalcium peroxide, preferably magnesium peroxide.The filter media is preferably used for oxidizing and removingsoluble iron and manganses from an aqueous fluid. The filter mayalso be used for removing and inactivating microorganisms fromfluids, e.g. aqueous fluids. Particulate filter aid having coated oradsorbed on the surface the aforementioned metal peroxide may beused as the particulate in the filter media, as well as the metalperoxide in particulate form.
