A method for treating water which comprises causing the water under treatment to contact a catalyst thereby deodorizing, sterilizing, and decoloring said water by the action of ozone or to decompose the remove ozone dissolved in said water, wherein said catalyst comprises a first catalyst component
A method for treating water which comprises causing the water under treatment to contact a catalyst thereby deodorizing, sterilizing, and decoloring said water by the action of ozone or to decompose the remove ozone dissolved in said water, wherein said catalyst comprises a first catalyst component formed of the oxide of at least one metal selected from the group consisting of titanium, silicon, and zirconium and a second catalyst component formed of at least one metal selected from the group consisting of manganese, iron, cobalt, nickel, cerium, tungsten, copper, silver, gold, platinum, palladium, rhodium, ruthenium, and iridium or a sparingly water-soluble compound of said metal, wherein manganese, iron, cobalt, nickel, cerium, tungsten, copper, and silver are used in said second catalyst component only as oxide or sulfide, and gold, platinum, palladium, rhodium, ruthenium and iridium are used in said second catalyst component only as metal, said catalyst comprising in the range of 70 to 99.99% by weight of said first catalyst component and in the range of 30 to 0.01% by weight of said second catalyst component, provided that the sum of the two catalyst components is 100%, and wherein said treatment is carried out at 0°to 60°C.
