Abstract：Scaling is a universal phenomenon for industrial circulating cooling water. In order to study the mechanism of the scale removal by the magnetized circulating water treatment for anti-scaling, the influences of the change in the physical properties of the magnetized water (viscosity, surface tension and the number of hydrogen bonding) and the change in the scaling structure (aragonite and calcite) on the variation of the system energy were summarized by the literature investigation on the study of the magnetized circulating water treatment for anti-scaling. Combining with the factors affecting the effect of the scale removal by the magnetized circulating water treatment for anti-scaling, for the divergence of the magnetic anti-fouling mechanism, the mechanism was discussed on the basis of the relevant experimental results about energy. When the liquid water was in the magnetic field, the number of the hydrogen bonds was increased, which formed more hydrated ions. It resulted in the reduction of the scale formation, the decrease of the system energy and the increase of the activation energy which can promote the transformation of hard deposit to soft dirt. The variation caused by the redistributing of the system energy can explain the common magnetic theory. And the factors affecting the scale removal by the magnetized water treatment were discussed.
