Publication number: 20120091061Abstract: Water from underground and other sources is brackish and not suitable for human consumption. Naturally present dissolved chemicals in water make it brackish. The precipitants and dissolved chemicals need to be separated from water to make it consumable. A combination of aeration systems, filtration systems, crystallizers and hydrophobic membrane carrying filter are used to desalinate the brackish water. Pressure retarded osmosis process using an apparatus is also used to further purify water. Various heat exchange apparatus are used for energy conservation and efficient processing of water in a feasible way. The disclosure enables to purify water and provide a useful technology to eradicate water scarcity.Type: ApplicationFiled: December 27, 2011Publication date: April 19, 2012Applicant: King Abdulaziz City for Organization Name Science and Technology "KACST"Inventor: Saad A.

Patent number: 8157993Abstract: In a wastewater treatment plant using methane gas, a by-product of anaerobic sludge digestion, to generate energy in a combustor to run the plant, a system for collecting the gas stream from the plant biological process and feeding the gas stream, containing nitrous oxide emissions, into the combustor. The nitrous oxide is thermally reduced down to nitrogen (N2) and oxygen (O2).Type: GrantFiled: January 21, 2010Date of Patent: April 17, 2012Inventor: Philip B. Pedros

Patent number: 8157995Abstract: 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: GrantFiled: January 27, 2011Date of Patent: April 17, 2012Assignee: Alcoa Inc.Inventors: Rajat S. Ghosh, Dennis Fulmer, Kevin Kitzman, John Smith

Publication number: 20120080382Abstract: The invention relates to a method and apparatus for restoring the extractive potential of organic hydroxyoxime-based extraction solution used in the recovery of metals by liquid-liquid extraction. The method is two-stage, in which an aqueous solution of hydroxylamine or some hydroxylamine compound is used in the reaction stage, and the removal of the undesirable compounds generated in the reaction occurs in the second stage by adsorption purification. The reaction stage and the adsorptive stage are carried out in a mixing tank.Type: ApplicationFiled: May 26, 2010Publication date: April 5, 2012Applicant: OUTOTEC OYJInventors: Erkki Paatero, Kai Jyrkkä, Sami Virolainen

Patent number: 8137547Abstract: A fluid treatment tank for use in a well fluid processing system. The tank is divided into at least three compartments, including an oil treatment compartment for receiving oil from a separator vessel of the well fluid processing system so as to allow stabilization and/or final separation and treatment of the oil, a reject treatment compartment for receiving reject fluid from one or more water treatment units of the well fluid processing system so as to allow gravitational separation of heavier and lighter components of the reject fluid, and a water treatment compartment for receiving de-oiled water from one or more water treatment units of the well fluid processing system so as to allow degassing and/or final separation of the water. Also, a well fluid processing system including such a fluid treatment tank.Type: GrantFiled: March 14, 2007Date of Patent: March 20, 2012Assignee: Hamworthy PLCInventors: Pål Jahre Nilsen, Matteo Chiesa, Peder Hansson, Helge Andersen

Patent number: 8137550Abstract: A fluid remediation system for removing particulates from an aqueous stream having a separation component and a clarifier component is described herein. The separation component can include a frame, a scalping shaker for receiving a primary slurry and forming a first effluent, a mud cleaner for receiving the first effluent and forming a second effluent, a desilter for receiving the second effluent and forming a third effluent, a tank for containing the effluents, agitators in the tank, and pumps for pumping the effluents. The clarifier component can include a second frame and a second tank for receiving the third effluent from the separation component, which forms a sludge and a clean effluent. The system can include a controller for controlling the system.Type: GrantFiled: November 19, 2010Date of Patent: March 20, 2012Assignee: Tri-Flo International, Inc.Inventor: Edward Beverly Moe
