<p>The water is conditioned after having circulated in a cylindrical enclosure (1) forming a magnetic protection screen, along a spiral path determined by baffles (12,13) around a central column of permanent magnets (8) mounted in opposition with interposition of soft iron studs (10) in a jacket (6) of electrically insulating material. The magnetic field of the magnets (8), which is concentrated in the cylindrical regions around the studs (10), enriches the water in the magnetically neutral regions which surround the magnets (8) in positive ions and negative ions alternately. The positive CaCO3 macromolecules which are in suspension in the potable water pass through the regions enriched in positive ions without change; but on passing through the regions enriched in negative ions their positive charge is gradually neutralised in the water and no longer on the walls of the conduits. The crystallisation nuclei which may result therefrom are then carried off by the water. The ionic imbalance thus produced in the water reduces the scaling existing beforehand in the conduits and storage vessels. The disappearance of the scale entails to a large extent that of the oxidation. <IMAGE></p> |
