On the basis of the electromagnetic anti-fouling dynamic simulation experimental platform

the influence of electromagnetic field on three water quality parameters

such as conductivity

pH value and dissolved oxygen

in the process of fouling formation was analyzed

with magnetic induction intensities of 0 and 200 Gs.Moreover

the correlation characteristics between water quality parameters and fouling resistance were studied by using the mathematical statistics method.The results of correlation analysis and partial correlation analysis indicate that

whether the electromagnetic field was applied

the correlation coefficient between conductivity and thermal resistance was the largest

then was the pH value

and the dissolved oxygen was the least

that is

the conductivity had a significant effect on fouling resistance in the heat exchanger.Compared with the situation with nonelectromagnetic field treatment

the correlation degree between water quality parameters and fouling resistance with electromagnetic field was weaker.The correlation analysis between water quality parameters and fouling resistance provides a powerful theoretical basis for establishing the suitable mathematical model and exploring the mechanism of electromagnetic anti-fouling.
