Patent number: 8349191Abstract: A method of treatment of water in an aquatic environment. Water is first pumped from a reservoir to a first mixing station. An inert gas is introduced into the pumped water at the first mixing station to provide inert gas saturated water, which inert gas saturated water will displace undesired gasses in the water in the reservoir. The inert gas saturated water is then pumped to a sparging column such that the inert gas and undesired gasses will be released from the inert gas saturated water to provide depleted water.Type: GrantFiled: February 15, 2011Date of Patent: January 8, 2013Assignee: Revalesio CorporationInventor: Anthony B. Wood

Patent number: 8348065Abstract: A separation apparatus for separating mud from water has an input tank device, a pipe device and a first separating assembly. The input tank device has an input tank. The pipe device has a first pipe having a first end and a second end. The first end of the first pipe is connected securely to the input tank. The first separating assembly has a main structure having a hydrocyclone. The hydrocyclone is connected to the second end of the first pipe. Accordingly, the hydrocyclone can efficiently and quickly separate mud from liquid of the raw water in the input tank.Type: GrantFiled: August 18, 2010Date of Patent: January 8, 2013Inventor: Shun-Tsung Lu

Patent number: 8337704Abstract: The invention concerns a device and a method for the manipulation of a liquid sample material in which magnetic microparticles are suspended whereby the microparticles have a functionalized surface and an analyte is bound to the surface. The sample material is introduced into a device with a liquid system through an injection device (50) and in a first mobile phase the sample material is carried to an extractor (90). In a first section (97a) of the extractor (90) the microparticles are immobilized by means of a magnetic field of a controllable device (96) and separated from the remaining sample material. By switching over of a switching unit (110) a second mobile phase (75) is carried to the extractor (90) and the second mobile phase (75) detaches the adsorbed analyte from the surface of the microparticles.Type: GrantFiled: December 4, 2008Date of Patent: December 25, 2012Assignee: Roche Diagnostics Operations, Inc.Inventor: Michael Vogeser

Patent number: 8329033Abstract: A fuel supply device (1), particularly for an internal combustion engine (6), is equipped with a particulate filter and a water trap. In order to improve the separation effect, while simultaneously reducing the separation material that is required, it is proposed to configure the water trap (5, 8, 30) as a separate component connected downstream of the fuel filer (4) and to provide it with a first separation stage made of coalescent material and a second separation stage made of hydrophobic material, and to dispose the separation stages such that between them the fuel is diverted.Type: GrantFiled: April 29, 2008Date of Patent: December 11, 2012Assignee: Mann & Hummel GmbHInventors: Martin Klein, Steffi Kiedaisch

Publication number: 20120305466Abstract: A structure for filtering water comprises a housing, an inlet pipe, a dirty-water pipe, an outlet pipe, and a membrane assembly. The inlet pipe is connected to a first end of the housing. The dirty-water pipe is connected to a second end of the housing. The outlet pipe is connected to a side of the housing. The membrane assembly is composed of multiple tubular membranes fitted within the housing, each tubular membrane defining a central passage therein, each tubular membrane defining multiple pores through a cylindrical wall surrounding the central passage, such that water fed from the inlet pipe can be filtered out of the membrane assembly to flow into the outlet pipe for a further treatment or a use point, or can be used to wash away impurities left in the membrane assembly and then be directed to the dirty-water pipe for a utilization.Type: ApplicationFiled: May 30, 2011Publication date: December 6, 2012Inventor: YAO-TSUNG WU
