Abstract :
The electromagnetic heating device based on the heat effect of secondary current and vortex hysteresis effect of magnetic materials was built for treating scaling waters. Water was circulated at a constant flow rate in the device. The effects of magnetic treatment for calcium carbonate crystallization were investigated. It was found that a series of changes have taken place in water´s physico-chemical characters after it was handled by electromagnetic field and the scale is aragonite. The mechanism of preventing and removing scale through magnetic treatment was also investigated.
