Characterization of the efficiency of antiscale treatments of water. Part II : Physical processes.

Résumé

The efficiency of physical antiscale treatments of water was evaluated by various techniques, such as chronoamperometry, electrochemical impedance and chronoelectrogravimetry. It was found that the antiscale electrolytic treatment is more efficient than magnetic treatment, at least for the commercial devices used here, and that it also has a longer lasting effect. The electrolytic process generates CaCO3 nuclei in suspension in the bulk water, which provokes homogeneous scaling rather than heterogeneous scaling on the walls which is to be avoided. If the small crystals generated in the bulk are eliminated by filtration, surface scaling is again observed.
