Abstract: The currenttreatment of circulating cooling water is limited to descaling with little scale inhibition，which israrely reported. This study proposed a new technology of electrochemical treatment of circulating cooling water by using simulating the treatment of circulating water by a high frequency electric field in electrolytic system. Optimal operational conditions were obtained by adjusting electrochemical parameters，and the mechanism of the process was analyzed. Based on the experimental data，the device was applied on a pilot scale at a facility. The results confirmed the optimal experimental conditions，with the current of 16 A，voltage of 5 V，plate spacing of 75 mm，and flow of 1000m3/h. The result suggested that this process had excellent scale inhibition convenience and efficiency.
