Abstract

Cette invention concerne le domaine de la purification de l'eau, notamment l'élimination d'ions de métaux lourds, et trouve des application dans le traitement des effluents des industries du cuir et de galvanoplastie et des entreprises travaillant les métaux non ferreux, entre autres. Ce procédé d'élimination des métaux lourds dans l'eau prévoit le traitement de l'eau par un système colloïdal comprenant de 0,3 à 1,3 % en poids de Fe(OH)3, de 3,2 à 6,4 % en poids de Fe(OH)2 et de 0,3 à 1,0 % en poids d'un chlorure de métal alcalin, le reste étant de l'eau. On procède à la précipitation des additifs puis à la séparation du précipité, le système colloïdal étant ensuite mélangé à l'eau à traiter dans une proportion variant de 1 à 10 ml pour 1 litre, à un pH se situant entre 8,0 et 9,2. Ce système colloïdal se présente sous la forme d'une suspension générée électriquement, laquelle peut être stabilisée, pour longue conservation, par l'ajout de 0,1 % à 1,2 % d'une substance choisie dans un groupe comprenant des silicates d'alumine naturels ou artificiels, de l'orthophosphate de calcium, ainsi que des polyélectrolytes organiques ou non organiques. Les particules de la suspension ont une taille variant entre 5 et 15 νm, une surface spécifique de 100 à 250 m2/g, la densité de la suspension variant entre 1,05 et 1,1 g/cm3. Le mode de réalisation principal permettant d'obtenir ce système colloïdal consiste en une dissolution électrochimique d'anodes de fer dans une solution aqueuse, sous une conductivité électrique au moins égale à 3.10?-3 ohm-1cm-1¿, et avec un soufflement d'air périodique jusqu'à ce que l'on dépasse un seuil de 10 % à 20 % en fer dissous trivalent.
