Abstract

Physical water treatment attracts more attention because of its environmental protection and economic characteristics. The scale inhibition efficiency of frequency conversion pulsed electromagnetic water treatment were measured by weighing method. The results show that the scale inhibition efficiency increases with the treatment time and the hardness of the simulated water. The effect of electromagnetic water treatment to corrosion behavior of carbon steel was investigated by electrochemical impedance spectroscopy and polarization curves. It shows corrosion inhibition to carbon steel after electromagnetic treatment for short time, and it promotes the corrosion of carbon steel when the treatment time was longer.
