PROBLEM TO BE SOLVED: To achieve a purification for the environment and the water quality by a method wherein a liquid metabolite by a lactic acid bacterium continues to be fed into equipment of a cooling tower at an interval of a fixed period so that the balance of microorganisms is kept in the equipment to prevent the generation of water-bloom and harmful germs. SOLUTION: A proper amount of a liquid metabolite by a lactic acid bacterium is measured in equipment of a cooling tower to be mixed into water circulating in a piping at an interval of a fixed period. As a result, the balance of microorganisms is kept in the equipment to prevent and remove possible water- bloom and harmful germs. This achieves a purification for the water quality in the cooling tower and for the environment in a building thereby creating a comfortable space. |
