Patent number: 7662290Abstract: The present invention removes contaminants from well water without creating the problem of large volumes of waste liquid disposal. It uses double-cone devices as pressure amplifiers which due to their lack of moving parts avoid the risk of additional contamination of the well and provide a prolonged lifetime. For toxic contaminants, a periodic purging of the concentrated contaminants is required. In the case of (sea) salt contamination, there is no waste brine to be continuously handled at all and the system may be run without interruption over an extended period. In this case, the brine is dumped into the well simply by periodically stopping the plant. The brine pours out of the double-cone unit(s) and due to its higher density, sinks down in the well without disturbing the operation of the purification plant.Type: GrantFiled: July 21, 2004Date of Patent: February 16, 2010Assignee: DCT Double-Cone Technology AGInventor: John Stark

De-oiled produced water is processed through a high pH/high pressure evaporator driven by a commercial watertube boiler. The vapor produced by the evaporator is suitable for the steam assisted gravity drainage (SAGD) method being utilized by heavy oil recovery installations, without the use of once through steam generators that require extensive chemical treatment, and without requiring atmospheric distillation, which requires high power consuming compressors. Evaporator blowdown may be further treated in a crystallizing evaporator to provide a zero liquid discharge (ZLD) system and, with most produced waters, at least 98% of the incoming produced water stream can be recovered in the form of high pressure steam.Type: GrantFiled: November 24, 2004Date of Patent: September 22, 2009Assignee: Aquatech International CorporationInventors: Keith R. Minnich, Mark C. Nicholson, RamKumar Karlapudi, Richard M. Schoen

Patent number: 7588692Abstract: The present invention is directed to a method and system that separates first particles from second particles, or white blood cells from red blood cells, by sedimentation in a fluid chamber with debulking of one of the first or second particles or red blood cells through the inlet of the fluid chamber. The method and system further includes fractionation of the remaining particles or white blood cells into selected subsets. In one embodiment of the instant invention a blood product containing white blood cells is loaded in a separation chamber, a diluting or sedimenting agent is added to encourage rouleaux formation of any red blood cells, the cells are sedimented and the red blood cells are removed.Type: GrantFiled: February 28, 2007Date of Patent: September 15, 2009Assignee: CaridianBCT, Inc.Inventors: Glenn Delbert Antwiler, Linda A. Taylor

Patent number: 7588688Abstract: The disclosed principles for providing a chemical-free filtering of particulate down below sub-micron levels, while concentrating the particulate into a sludge. The disclosed principles integrate cross-flow filtration (i.e., micro-filtration or ultra-filtration) with a settling tank (or “weir”) to provide sequential filtration and dewatering of an aqueous media. The disclosed technique operates chemical-free and is continuous. Applications for systems and processes in accordance with the disclosed technique are wide, and include aggregate fines removal, sediment removal, replacement for clarifiers, etc.Type: GrantFiled: March 2, 2007Date of Patent: September 15, 2009Assignee: Purifics Environmental Technologies, Inc.Inventors: Brian E. Butters, Anthony L. Powell

Patent number: 7572376Abstract: Disclosed herein are processes for the recovery of 1,3-propanediol from an aqueous feed stream. The present invention involves contacting an aqueous feed stream that comprises water, 1,3-propanediol, and at least one contaminant with at least one solvent extractant to form a mixture. The mixture is separated into a first phase and a second phase. The second phase comprises a majority of the water from the aqueous feed stream. The first phase comprises solvent extractant and at least some of the 1,3-propanediol that was present in the aqueous feed stream. The weight ratio in the first phase of 1,3-propanediol to any one contaminant present is greater than the weight ratio of 1,3-propanediol to the same contaminant in the aqueous feed stream prior to the aqueous feed stream being contacted with the solvent extractant. The first phase can be removed from the separated second phase in order to recover the 1,3-propanediol.Type: GrantFiled: February 13, 2006Date of Patent: August 11, 2009Assignee: Tate & Lyle Ingredients Americas, Inc.Inventors: Avraham M. Baniel, Robert P. Jansen, Asher Vitner, Anthony Baiada

Patent number: 7572378Abstract: A process for irrigation involves monitoring reclaimed water, and treating it when necessary. The reclaimed water is tested with monitors to obtain results for water quality characteristics, including: pH; residual chlorine; and, sodium. These results are inputted to a computerized data handling system for data collection, storage and analysis for comparison to predetermined acceptable ranges for water quality characteristic, and to show any deviation from said acceptable ranges. Either alarms are set off or treatment occurs or both, when deviations are observed. Treatment includes a dechlorination system to correct active chlorine, and, optionally, an oxidation system. There is also a reverse osmosis step for reduction of salts, such as sodium. Other monitors may include one or more of hardness; turbidity; alkalinity; conductivity and nitrates.Type: GrantFiled: December 15, 2005Date of Patent: August 11, 2009Assignee: Turf Sentry, Inc.Inventors: Peter L. Rosen, Robert D. Hodges

Patent number: 7569245Abstract: Deboned meat is subjected to processing in a surimi-type procedure in order to substantially reduce the heme content and thus the color intensity of the deboned meat, with bone marrow components and fat also being removed. When desired, the washed meat is subjected to dewatering, such as by pressing, in order to provide a color and fat reduced deboned meat. Multiple-stage separation is practiced, and the protein yield of the washed meat is advantageously elevated.Type: GrantFiled: May 26, 2004Date of Patent: August 4, 2009Assignee: Kraft Foods Holdings, Inc.Inventors: Iksoon Kang, Gary Robert Skaar, William Nathaniel Gale Barron, III, Cory Jay Painter, James Donald Colby, Henri K.
