ABSTRACT:
A method for treating fluid to remove undesirable constituents contained therein such as chlorine and nitrate constituents is disclosed. The method includes passing fluid containing the undesirable constituents through a bed of metal particulate matter. The metal particulate matter is preferably chosen from metals having favorable redox potentials relative to the redox potentials of the undesirable constituents so as to establish conditions for spontaneous oxidation and reduction reactions between the undesirable constituents and the metal particles.
