PURPOSE:To prevent the undermentioned equipment from sticking algae, fur, iron rust, carbonate, etc., onto said equipment by mixing the aqueous solution of stabilized chlorine dioxide with a metallic ion-sealing agent and a rust- preventing agent to make a mixture as the circulating water for a cooling tower and the heat-exchanger of a refrigerator. CONSTITUTION:0.5-30%, preferably 5% aqueous solution of stabilized chlorine dioxide or chlorite is added with 0.5-10%, preferably 3% water-soluble rust- preventing agent and 0.1-10%, preferably 5% metallic ion-sealing agent to make an aqueous solution, which is added into the circulating water for a cooling tower and the heat-exchanger of a refrigerator. As a result, cooling water is extremely effective for removing algae and preventing its growth, for removing fur and iron rust and preventing their generation and for removing carbonate, etc., and preventing their sticking.
