MAGNETIC TREATMENT OF WATER AND SCALING DEPOSIT

A series of experiments confirms that a suitable magnetic field is able to prevent scale deposit on water contining Ca+2 ions and carbonic species. The magnetic field acts inducing the precipitation of CaCO3 in crystalline form, (calcite or aragonite) that does not adhere to the walls and tubes, whereas amorphous CaCO3, which is formed in absence of the magnetic field, is responsible of the scale deposit. The nucleating effect of Fe ions on the formation of crystalline CaCO3, in the presence of the magnetic field, is discussed
