Patent number: 8758622Abstract: A method of cleaning a membrane (6) in a membrane filtration system by flowing gas bubbles past the surfaces of the membrane (6) to scour accumulated solids therefrom. The method includes flowing a liquid past a supply of gas; creating a reduced pressure within the liquid flow to cause a flow of gas from the supply of gas (9) into the liquid flow and form gas bubbles therein and then flowing the liquid containing the gas bubbles past the surfaces of the membrane (6) to scour the surfaces thereof. Apparatus for performing the method is also disclosed.Type: GrantFiled: December 22, 2005Date of Patent: June 24, 2014Assignee: Evoqua Water Technologies LLCInventor: Joachim Muller

Patent number: 8506812Abstract: The present invention relates to a membrane separation method and a relevant equipment, in particular to a method and an equipment for membrane separation utilizing concentration polarization during membrane filtration process, especially, to a concentration process and equipment and a drawer special for drawing a concentration polarization layer. The direct removal of the concentration polarization layer from membrane surface not only decreases the adverse influence of concentration polarization on membrane separation but also obtains concentrated retention components, thereby significantly improving the ability to maintain membrane flux, solving the twinborn problems concerning concentration polarization and membrane fouling during the membrane separation process, and achieving a high-efficiency concentration for retention components.Type: GrantFiled: July 23, 2012Date of Patent: August 13, 2013Assignee: Institute of Process Engineering, Chinese Academy of SciencesInventors: Yinhua Wan, Xiangrong Chen, Zhiguo Su, Guanghui Ma, Xiaoguang Jiao, Fei Shen, Zhanfeng Cui

Publication number: 20110049015Abstract: A system and method for removing and managing water in liquid hydrocarbons is disclosed. The system and method utilize a water absorbent filter, such as one that utilizes super absorbent polymers, cellulose, cotton or other suitable material to remove water from the system that is either present as free water or as dissolved moisture within the liquid hydrocarbon. The super absorbent polymer filter can be regenerated through the introduction of a dried liquid hydrocarbon, through the use of an air drying system, or a combination of both.Type: ApplicationFiled: June 30, 2010Publication date: March 3, 2011Applicant: Donaldson Company, Inc.Inventors: Brian D. Babcock, James Doyle, Gregory L. Lavallee, Michael John Madsen, Philip Edward Johnson

Patent number: 7824547Abstract: A filter apparatus, particularly for filtering coolant/lubricant from a machining, including a filter tank having an inlet for the liquid to be filtered, an outlet for the filtered liquid and a belt of filter medium adapted to circulate within the filter tank and having a top side and a bottom side. The liquid to be filtered is introduced below the bottom side and is discharged between the top side and the bottom side. The filter material of the bottom side separates the unfiltered liquid from the filtered liquid and prevents floating particles in the liquid from reaching the outlet for the filtered liquid.Type: GrantFiled: September 6, 2006Date of Patent: November 2, 2010Assignee: Mann + Hummel GmbHInventors: Luc Reynders, Marcel Peumans
