Abstract
A method for treating fluid to remove hydrogen sulfide and sulfur dioxide is disclosed. The method includes passing fluid containing the hydrogen sulfide and/or sulfur dioxide 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 these undesirable constituents so as to establish conditions for spontaneous oxidation and reduction reactions between the undesirable constituents and the metal particles.
Claims13
A long lived low maintenance method for reducing the concentration of undesirable inorganic hydrogen sulfide which is present in drinkable water, said hydrogen sulfide having a first redox potential, said method comprising passing said water containing said hydrogen sulfide through a bed of metal particles, said metal particles comprising copper and zinc, said metal particles having a sufficient surface area and a second redox potential such that relative to said first redox potential conditions are established for spontaneous inorganic oxidation and reduction reactions between said undesirable hydrogen sulfide and said metal particles when said fluid is in contact with said metal particles.
