A fluid treating method for treating fluid to reduce the concentration of undesirable nitrogen compounds and/or metal constituents contained therein is disclosed. The method utilizes a bed of metal particulate matter. The metal particulate matter comprises copper. Preferably, the metal particulate also contains zinc and can be in the form of an alloy. The fluid treated is often water, preferably, drinking water. Among the nitrogen compounds that may be effected by the present method are inorganic nitrates and nitrites and/or metals may be aluminum, arsenic, barium, cadmium, chromium, copper, gold, iron, lead, mercury, selenium and silver. |
