Abstract
In order to improve the scale inhibition effect of polyepoxysuccinic acid, a high-voltage electrostatic field was introduced to combine with polyepoxysuccinic acid in the water sample flowing through an electrostatic water treatment apparatus. The synergistic scale inhibition performance was investigated by the static and dynamic experiments and the CaCO3 deposits formed in the static experiments were analyzed by IR and SEM. The results showed that there existed obvious synergistic scale inhibition effect between polyepoxysuccinic acid and the electrostatic field. The efficiency of the scale inhibition of polyepoxysuccinic acid was improved by 18.9 % in the static experiment and 14.5 % in the dynamic experiment under the influence of the electrostatic field. The electrostatic field was in favour of the formation of aragonite and the synergism between polyepoxysuccinic acid and the electrostatic field distorted CaCO3 crystallite completely and made the CaCO3 deposit more dispersive which could be washed away by water flow easily.
