摘要

PROBLEM TO BE SOLVED: To provide a slime preventing method in an open circulating cooling water system capable of suppressing the corrosion by metals and effectively suppressing the generation of slime. SOLUTION: In the method for preventing slime by adding chlorine to the open circulating cooling water system, chlorine water obtained by generating residual chlorine by electrolyzing a saline solution is added and the concentrated cooling water is electrolyzed to generate residual chlorine.
