A method for removing ionic, organic and elemental mercury from aqueous streams such as wastewater streams from hydrocarbon processing. The method comprises four primary removal steps. First, a mercury precipitant is added to the stream to convert dissolved ionic species of mercury water-insoluble form. The majority of these precipitated solids, as well as other forms of particulate mercury, are subsequently removed by means of gas flotation. Following the flotation step, additional particulate and precipitated ionic mercury removal is accomplished with media filtration and finally, activated carbon acts to remove the remaining dissolved ionic mercury species as well as elemental and organic forms of mercury.

L'invention concerne un procédé d'élimination de mercure ionique, organique et élémentaire de courants aqueux tels que les courants d'eaux usées provenant d'un traitement d'hydrocarbures. Le procédé comprend quatre étapes d'élimination primaires. Tout d'abord, un précipitant de mercure est ajouté au courant pour convertir les espèces ioniques dissoutes du mercure en une forme insoluble dans l'eau. La majorité de ces solides précipités, ainsi que d'autres formes de particules de mercure, sont ultérieurement éliminées au moyen de flottation à l'air dissous. A la suite de l'étape de flottation, l'élimination du mercure ionique particulaire et précipité supplémentaire est accomplie avec une filtration de milieu, et enfin, du charbon actif agit pour éliminer des espèces de mercure ionique dissoutes restantes ainsi que les formes élémentaires et organiques du mercure.
