Abstract

Magnetic treatment of aqueous solutions containing dissolved CaCO3 is known to affect its precipitation exerted by heating or raising the pH of the solution. In this work, experiments have been performed on two kinds of water: (a) a simulated water containing only CaCO3 as dissolved salt and (b) a real brackish water sample of high total hardness from an industrial area containing a wide range of impurity salts. It has been discovered for the first time that using a sinusoidal magnetic field, treatment at a frequency of ca. 150 kHz (for a range of 0–1000 kHz) results in the maximum calcite precipitation independent of the initial water composition. The discovered phenomenon could be explained based on the resonance taking place due to the synchronization of the induced magnetic field with the proton exchange rate of water molecules.
