Magnetic water treatment

Carbonates formed by heating water containing approximate to 120 mg(Ca)/l a re characterized by X-ray diffraction and electron microscopy. Tests on 32 pairs of samples establish, at the 99.9% probability level, that drawing wa ter through a static magnetic field(B approximate to 0.1T, del B approximat e 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 ex tends beyond 200 h. (C) 2000 Elsevier Science B.V. All rights reserved.
