<p>Process for the treatment of a medium, in particular an aqueous medium, in which the said medium is subjected to the action of a field created between at least two means of transfer (4, 5) so as to modify the nucleation and/or the formation and/or the growth of crystals, in particular of CaCO3, at least one of the said means of transfer receiving substantially rectangular electrical signals comprising a first phase in which the signal is close to a lower level (I) and a second phase in which the signal is close to a higher level (II), the said signals exhibiting a series of damped variations when they are close to the lower level (I) or to the upper level (II). <IMAGE></p> |
