<p>PROBLEM TO BE SOLVED: To provide a method for preventing scaling in a cooling water system capable of effectively preventing scaling in the cooling water system for a heat exchanger in an air conditioning system for buildings, a common factory, a petrochemical complex, and so forth. SOLUTION: The method for preventing scaling in an open circulatory cooling water system, wherein the cooling water is made to flow through an apparatus including means to make the cooling water contact inorganic matter same as or similar to the scale produced in the cooling water system, is characterized in that the cooling water passes through an electrolyzing process prior to its contact with the inorganic matter same as or similar to the scale.</p> |
