METHOD FOR PREVENTING SCALE AND SLIME

摘要

PROBLEM TO BE SOLVED: To provide a method for preventing scale and slime capable of simultaneously preventing scale trouble and slime trouble by simultaneously performing the removal of a hardness component and the supply of an oxidizing agent without using chemicals in a cooling water system. SOLUTION: In the preventing method of the scale and the slime in which the hardness component in water is stuck and removed as solid on the surface of a cathode by applying voltage to an electrode immersed in the cooling water and also chloride ion is converted into an oxidizing agent on the surface of an anode, at least anode out of electrodes is the electrode having the element or oxide of a platinum group element on the surface.
