<p>PROBLEM TO BE SOLVED: To maintain the function of a cooling tower by inhibiting the growing of algae and slime in a water-sprinkling tank by a method that is harmless and does not have any risk of environmental pollution. SOLUTION: A light catalyst is immobilized in the water-sprinkling tank 2 that the cooling tower has, the oxidation operation of the light catalyst being grown by receiving the application of ultraviolet rays is utilized, and the growing of the algae in the water-sprinkling tank is inhibited. The light catalyst is a particle P made of titanium oxide, is added in a ratio of 20% or more to an organic adhesive A, and is applied, as a paint T, to the inner surface of the water-sprinkling tank where sunlight is directly applied.</p> |
