Magnetic water treatment

Carbonates formed by heating water containing approximate to 120 mg(Ca)/l are characterized by X-ray diffraction and electron microscopy. Tests on 32 pairs of samples establish, at the 99.9% probability level, that drawing water through a static magnetic field(B approximate to 0.1T, del B approximate to 10 T/m) increases the aragonite/calcite ratio in the deposit. There is an incubation period of several hours, and memory of magnetic treatment extends beyond 200 h. (C) 2000 Elsevier Science B.V. All rights reserved.
