Abstract

Based on the online monitoring experimental rig of water treatment technology for fouling prevention and corrosion inhibition

the effect of electromagnetic field on CaCO3 fouling behavior was studied.The crystallization of CaCO3 was studied by monitoring the change of fouling resistance.The crystal form and crystal appearance of calcium carbonate fouling were qualitatively and quantitatively analyzed by Quanta 200 SEM and X'Pert Pro XRD to describe the effect of electromagnetic field on calcium carbonate fouling.Electromagnetic field could reduce the rate of scaling on the surface of heat exchanger. The mass fraction of the calcite of scale sample decreased from 100% to 40.55%

and the mass fraction of aragonite increased to 59.45%.
