Patent number: 8673152Abstract: Wastewater treatment systems, methods and apparatus for polishing a wastewater stream comprising a plurality of contaminants are provided. One system includes a vessel containing a plurality of natural media filtration agents selected to remove selected ones of the plurality of contaminants from the wastewater stream. In one embodiment, the vessel includes a bed of bauxite residue and at least one other natural media filtration agent. In another embodiment, the vessel includes a bed of compost and at least one other natural media filtration agent. The vessel includes a wastewater inlet that is in fluid communication with one or more of the natural media filtration agents. The vessel includes a wastewater outlet that is in fluid communication with one or more of the natural media filtration agents.Type: GrantFiled: May 3, 2013Date of Patent: March 18, 2014Assignees: Alcoa Inc., Corporate Environmental Solutions LLCInventors: John R. Smith, Jaw K. Fu, Rajat Ghosh, Kevin Kitzman, Jonell Kerkhoff, Robert C. Horger, Dennis L. Fulmer, Aniruddha Bhattacharyya, Andrew C. Middleton, Robin L. Weightman

Publication number: 20120160757Abstract: Systems and associated methods for treating contaminant-containing wastewater are provided. The systems generally include a reducing zone for reducing the oxidation-reduction potential of the water and a clean-up zone comprising zero valent iron for removing at least a portion of the contaminant from the contaminant-containing water. The systems are operable to remove one or more contaminants from the contaminant-containing water and are operable for extended durations without clogging due to the formation of iron hydroxides.Type: ApplicationFiled: February 29, 2012Publication date: June 28, 2012Applicant: Alcoa Inc.Inventors: Rajat S. Ghosh, Dennis Fulmer, Kevin Kitzman, John Smith
