Abstract

The invention relates to a method for reducing the concentration of certain metals in the composition of water. Said method consists in carrying out microelectrolysis of the water that makes up the electrolyte, the amperage of the electric current used ranging from15µA and 200 A/m or m2 of electrodes; the voltage advantageously ranging from 20 µ.V and 48 V. According to one embodiment, the device for carrying out said method comprises a reactor (1). The water to be treated arrives in the lower part (2), the treated water is recovered in part (3), the carbonate and calcium and the iron oxide are recovered at the base. The invention can be used for treating water such as water for human consumption.
