Abstract: The invention relates to a device for forming concretions in an electrolytic medium by electrolysis, the device comprising an anode and a cathode device connected to each other, the cathode device comprising an arrangement of metal conductors forming a mesh that can be developed in a plane, in a plane P, the cathode device having a surface coefficient ? of between 20% and 150%, in which: ?=chemical surface area/influence surface area; the chemical surface area corresponding to the total surface area of the metal conductors intended to be in contact with the electrolytic medium; the influence surface area corresponding to the orthonormal projection of an influence volume in the plane P; and the influence volume corresponding to the volume that extends at any point in space within two centimetres of one of the metal conductors when the mesh is considered developed in a plane, in the plane P.

Abstract: The invention relates to a device for forming concretions in an electrolytic medium by electrolysis, which comprises an anode 110 and a cathode 120 submerged in the electrolytic medium and a regulating circuit 100 configured to regulate an electrolysis current in order to form concretions on the cathode 120. The anode 110 and the cathode 120 are used as a current source for supplying the electrolysis process and are connected in the regulating circuit by at least one regulating element capable of limiting the electrolysis current.

Abstract: Process for capturing and cleaning up pollutants by the formation of cement or concrete by electrolysis, the creation of a rocky conglomerate, assembly of sediments linked together by a calcium-magnesium deposit acting as binder. This process is thus applicable to the decontamination of ports, by enabling the capture of pollutants and by containing them in a sediment matrix.
