Abstract: front page image
(EN)Process, apparatus and article for treating an aqueous solution containing biological contaminants. The process includes contacting an aqueous solution containing a biological contaminant with an aggregate composition comprising an insoluble rare earth-containing compound to form a solution depleted of active biological contaminants. The aggregate includes more than 10.01% by weight of the insoluble rare earth-containing compound. The insoluble rare earth-containing compound can include one or more of cerium, lanthanum, or praseodymium. A suitable insoluble cerium-containing compound can be derived from a cerium carbonate, a cerium oxalate or a cerium salt. The composition can consist essentially of cerium oxides, and optionally, a binder and/or flow aid. The aggregate includes no more than two elements selected from the group consisting of yttrium, scandium, and europium when the aggregate is to be sintered. Although intended for a variety of fluid treatment applications, such applications specifically include removing or deactivating biological contaminants in water.
(FR)L'invention concerne un procédé, un appareil et un article de traitement d'une solution aqueuse contenant des polluants biologiques avec une composition agrégée contenant un composé insoluble comprenant des terres rares afin d'obtenir une solution sans polluants biologiques actifs. L'agrégat contient plus de 10,01% en poids du composé insoluble comprenant les terres rares. Le composé insoluble comprenant des terres rares peut contenir un ou plusieurs éléments parmi le cérium, le lanthanum ou le praséodymium. Un composé insoluble adapté contenant du cérium peut être dérivé d'un carbonate de cérium, d'un oxalate de cérium ou d'un sel de cérium. La composition contient essentiellement des oxydes de cérium et, éventuellement, un liant et/ou un adjuvant d'écoulement. L'agrégat ne comprend pas plus de deux éléments sélectionnés dans le groupe composé d'yttrium, de scandium et d'europium lorsque l'agrégat doit être fritté. Bien que destinées à diverses applications de traitement fluidique, ces applications comprennent spécifiquement l'élimination ou la désactivation des polluants biologiques de l'eau.
