Title (EN) MIXED ALUMINUM (III) AND IRON (II) SALT SOLUTION FOR ENHANCING THE HYBRID ZERO-VALENT IRON MEDIA SYSTEM REACTIVITY FOR TREATING METAL-CONTAMINATED WASTEMATER
(FR) SOLUTÉ SALIN MIXTE D'ALUMINIUM (III) ET DE FER (II) POUR AMÉLIORER LA RÉACTIVITÉ DU SYSTÈME DE SUPPORT DE FER À VALENCE ZÉRO HYBRIDE POUR LE TRAITEMENT DE DÉCHETS CONTAMINÉS PAR DU MÉTAL
Abstract:
(EN) Methods for reducing the concentration of one or more contaminants in water using zero-valent iron media. In the method, a mixed aluminum (III) and iron (II) salt solution is added to water containing one or more contaminants that is in contact with a zero-valent iron media that comprises (a) a reactive solid comprising zero-valent iron and one or more iron oxide minerals in contact therewith and (b) magnetite to provide an aqueous reaction medium. The aqueous reaction medium is contacted with the zero-valent iron media for a period of time sufficient to reduce the concentration of one or more of the contaminants.
(FR) L'invention concerne également des procédés de réduction de la concentration d'un ou plusieurs contaminants dans l'eau à l'aide de milieux ferreux à valence zéro. Dans le procédé, un soluté salin mixte d'aluminium (III) et de fer (II) est ajouté à de l'eau contenant un ou plusieurs contaminants qui sont en contact avec un milieu de fer de valence zéro comprenant (a) un solide réactif comportant du fer de valence zéro et un ou plusieurs minéraux d'oxyde de fer en contact avec celui-ci et (b) de la magnétite pour fournir un milieu réactionnel aqueux. Le milieu réactionnel aqueux est mis en contact avec le milieu ferreux de valence zéro pendant une durée suffisante pour réduire la concentration d'un ou plusieurs des contaminants.
