Abstract: A system for reducing a level of metallic contaminants from an aqueous stream is described, including at least one of an aluminum oxide sorption media and an ion exchange media (media 1) and a functionalized activated alumina media (media 2), wherein the system is configured to: a. lower the pH of the metallic contaminant -contaminated aqueous stream to less than 6, b. contact the metallic contaminated aqueous stream with at least one of the aluminum oxide sorption media and the ion exchange media (media 1) c. contact the metallic contaminant-contaminated aqueous stream with the functionalized activated alumina media (media 2) wherein the contact with the at least one of the aluminum oxide sorption media and the ion exchange media and the functionalized activated alumina media forms a metallic contaminant-reduced aqueous solution; and d. discharge a metallic contaminant -depleted aqueous solution.

Abstract: Techniques for reduction of copper from aqueous streams using an iron promoted activated alumina are disclosed. An adsorbent media composition that reduces copper levels in an aqueous feed stream includes an iron containing activated alumina. A process for reducing copper levels in an aqueous fluid using an iron promoted activated alumina sorption media includes contacting the aqueous fluid containing a copper contaminant with the iron promoted activated alumina to achieve reductions in copper from the aqueous fluid.
