Title (EN) METHODS FOR THE PURIFICATION OF CONTAMINATED WATERS
(FR) PROCEDES POUR L'EPURATION DES EAUX CONTAMINEES
Abstract:
(EN) The present invention describes a method for the purification of waters containing high levels of contaminants by sequentially intermixing with the contaminated water a first anionic polymer, a cationic polymer, and a second anionic polymer, and then separating the contaminants from the water.
(FR) La présente invention a trait à un procédé pour l'épuration des eaux contenant des niveaux élevés de contaminants par le mélange séquentiel avec les eaux contaminées d'un premier polymère anionique, d'un polymère cationique, et d'un deuxième polymère anionique, suivi de la séparation des contaminants des eaux
