Reasonable selection of electromagnetic frequency is one of the necessary conditions for the best result of electromagnetic anti-scaling. This research designed a set of static electromagnetic experiment with electrical conductivity method, based on the analysis of the present and commonly used anti-scaling performance evaluations. Titration experiment was conducted according to the conductivity titration method. The characteristics of varying conductivity with time in the titration process under the given experimental conditions were compared. The effects of different frequency electromagnetic fields on the scale inhibition performance were investigated. The results showed that conductivity changed over time under the different electromagnetic frequencies. The regression model and the optimum frequency of electromagnetic anti-scaling were obtained. The method developed in this research is stable and repeatable and could effectively meet the needs of the accurate and rapid evaluation of electromagnetic anti-scaling performance.
