Filtering medium for fluid purification

Abstract

A filtering medium, a method for the production thereof, the use of said filtering medium and a method for reducing the content of multiple contaminants simultaneously in fluids by means of said filtering medium, wherein said filtering medium has or includes at least one of the following: a mixture (A) containing a major part of an iron-based powder and a minor part of a silver powder, an iron-silver powder alloy (B), and an iron-based porous and permeable composite containing silver (C).

1 . A filtering medium for reducing the content of contaminants in fluids, wherein said filtering medium comprises iron and silver in a form chosen from at least one of:
 a mixture (A) comprising a major part of an atomized iron-based or iron powder and a minor part of a silver powder,   an iron-silver powder alloy (B), and   a silver containing iron-based porous and permeable composite (C);   and wherein said contaminants are selected from the group consisting of chlorine containing compounds, nitrates, nitrites, heavy metals, toxic inorganic substances, toxic organic compounds, microorganisms and/or combinations thereof.
