Abstract
Hydrogen peroxide or a hydrogen peroxide producing agent is added to a water system having copper or copper alloy such as a thermal storage water system or a closed water system whereby the concentration of hydrogen peroxide in the circulating water becomes 1 to 200 mgH.sub.2 O.sub.2 /L. Hydrogen peroxide produces oxygen and oxygen works microbes directly so as to remove the microbial fouling and thus prevent the pitting corrosion in copper or its alloy due to microbial contamination.
