    Abstract: A process for treating a fluid comprising at least one chemical contaminant. The process comprises the steps of: (i) contacting the fluid with a particulate adsorbent material; (ii) allowing the adsorbent material to adsorb the chemical contaminant to produce a substantially purified fluid and a contaminant-carrying adsorbent material; (iii) separating the contaminant-carrying adsorbent material from the substantially purified fluid; (iv) contacting the contaminant-carrying adsorbent material with an aqueous slurry of a photocatalytic metal oxide powder in the presence of an electron acceptor and electromagnetic radiation in at least one of ultraviolet and visible regions; (v) allowing the contaminant to decompose to form a product which dissociates from the contaminant-carrying adsorbent to provide a regenerated adsorbent material, the aqueous slurry and the product; (vi) separating and recycling the regenerated adsorbent material to step (i); and (vii) recycling the aqueous slurry to step (iv). The process may be used to remove contaminants from and thereby purify fluids such as water, off-gases from air stripping processes and chimney gases.

    Abstract: Procédé de traitement d'un fluide contenant au moins un contaminant chimique. Le procédé consiste: (i) à mettre en contact le fluide avec un matériau adsorbant particulaire; (ii) à laisser ledit matériau adsorbant adsorber le contaminant chimique, de manière à obtenir d'une part un fluide sensiblement purifié et d'autre part un matériau adsorbant contenant le contaminant; (iii) à séparer du fluide sensiblement purifié ledit matériau adsorbant contenant le contaminant; (iv) à mettre en contact le matériau adsorbant contenant le contaminant avec une boue aqueuse de poudre d'oxyde métallique photocatalytique en présence d'un capteur d'électrons et d'un rayonnement électromagnétique dans au moins une des régions de l'ultraviolet et du visible; (v) à laisser se décomposer le contaminant, de manière à obtenir un produit qui s'est dissocié de l'adsorbant contenant le contaminant pour donner un matériau adsorbant régénéré, la boue aqueuse et le produit; (vi) à séparer et recycler le matériau adsorbant régénéré vers l'étape (i); et (vii) à recycler ladite boue vers l'étape (iv). Le procédé peut servir à éliminer des contaminants contenus dans des fluides tels que l'eau, les effluents gazeux de procédés de séparation à air et les gaz de fumée, et ainsi à les purifier.
