Abstract
(EN) A method of recovering metal from a chemical bath (100) for chemically treating a structure with metal, wherein the method comprises supplying a chemical composition comprising metal from the chemical bath (100) to a membrane distillation device (106), separating at least part of the metal in the membrane distillation device (106), and reintroducing the separated metal into the chemical bath (100).
(FR) L'invention concerne un procédé de récupération de métal à partir d'un bain chimique (100) pour le traitement chimique d'une structure avec du métal, le procédé comprenant l'alimentation d'une composition chimique comprenant du métal à partir du bain chimique (100) à un dispositif de distillation à membrane (106), la séparation d'au moins une partie du métal dans le dispositif de distillation à membrane (106), et la réintroduction du métal séparé dans le bain chimique (100).
