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 15u A et 200 A/m2 d'électrodes ; la tension se situe avantageusement entre 20u.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.The invention relates to a method for reducing the concentration of certain metals in the composition of water. This process consists in carrying out a microelectrolysis of the water constituting the electrolyte; the amperage of the electric current used being between 15u A and 200 A / m2 of electrodes; the voltage is advantageously between 20u.V and 48 V. According to one embodiment; the device for implementing this method comprises a reactor (1); the water to be treated arriving in the lower part (2); the treated water being recovered in part (3); calcium carbonate and iron oxide being recovered at the base (4). Application to the treatment of water especially for human consumption.
