Abstract

L'invention concerne un procédé pour la diminution de la concentration de certains métaux dans la composition de l'eau. Ce procédé consiste à effectuer une micro-électrolyse de l'eau constituant l'électrolyte, l'ampérage du courant électrique utilisé se situant entre 15µA et 200 A/m ou m2 d'électrodes; la tension se situe avantageusement entre 20 µ.V et 48 V. Selon un mode de réalisation, le dispositif de mise en oeuvre de ce procédé comprend un réacteur (1), l'eau à traiter arrivant en partie inférieure (2), l'eau traitée étant récupérée en partie (3), le carbonate de calcium et l'oxyde de fer étant récupérés à la base (4). Application au traitement de l'eau notamment destinée à la consommation humaine.
