Publication number: 20140091020Abstract: An autonomous filter device and a method for improving the filter life and performance is disclosed. The filter element is equipped with one or more sensors, adapted to measure one or more characteristics. In response to the measured characteristic, the control logic within the filter element is able to determine an appropriate response. For example, the control logic may determine that a sudden, but temporary, blockage has occurred in the filter membrane. In response, the control logic may initiate a specific response designed to alleviate the blockage. The control logic will then determine the success of the response, based monitoring any change in the fluid characteristics. Based thereon, the control logic may alert the operator that the filter element must be replaced. Alternatively, if the response was successful in correcting the blockage, the control logic need not notify the operator, as the filter element is back to normal operating operation.Type: ApplicationFiled: October 15, 2013Publication date: April 3, 2014Applicant: EMD Millipore CorporationInventors: Aaron Burke, Anthony DiLeo, Timothy O'Brien

Publication number: 20130306569Abstract: A water treatment device may comprise a photocatalytic oxidation (PCO) element, an oxide generation module, a flow switch, and a plurality of water-conveying elements. The oxide generation module may comprise a housing, an oxide generator, and a fan arranged such that, when the fan is powered on, a ducted flow of air passes along the oxide generator. The plurality of water-conveying elements may comprise a vacuum generation element. While the flow switch indicates that water is not flowing through the plurality of water-conveying elements, the PCO module and the oxide generator may be configured in an OFF state.Type: ApplicationFiled: May 20, 2013Publication date: November 21, 2013Inventor: Allen Johnston

Patent number: 8585892Abstract: A wastewater treatment system includes independent wastewater treatment facilities. Each of the facilities has a number of wastewater treatment subsystems. A wastewater collection subsystem holds wastewater to be treated. A pump subsystem moves wastewater from a wastewater collector to a filtration subsystem having a bioreacting filter. The filter has a sump and a fluidized-bed filter therein and supports the filter upright. The filter has an upwardly expanding, hollow, conical filter body with filter media. A monitoring subsystem measures wastewater process parameters. Control devices receive control commands and, dependent upon the command received, alter parameters of the wastewater treatment subsystems.Type: GrantFiled: June 3, 2010Date of Patent: November 19, 2013Assignee: Biofilter Systems, LLCInventors: Mark B. Robertson, David O'Keefe, John D. Cox, Daniel T. White

Patent number: 8580109Abstract: A water filter system includes a filter unit having a body portion adapted to be rotatingly received into a filter head assembly. An engagement protrusion extends from the body portion and is adapted for reception in a complementary receiver in the filter head assembly. An electronic device is disposed on the filter unit having a memory storage unit. A laterally extending key member is disposed on the body portion between the first engagement surface and the second engagement surface. The laterally extending key member is adapted to reposition an interference member from an interference position, whereby the body portion can be fully inserted into the filter head assembly to a non-interference position, whereby the body portion can be fully inserted into the filter head assembly.Type: GrantFiled: September 15, 2011Date of Patent: November 12, 2013Assignee: Whirlpool CorporationInventors: Christopher A. Kruckenberg, John W. Morrison, Peter J. Richmond, Jeffrey A. Spindler

Patent number: 8580110Abstract: A proposed blood treatment apparatus includes: a blood treatment unit, a pair of fluid pumps and a pair blood pumps. The blood treatment unit is configured to receive untreated blood and fresh blood treatment fluid, and emit treated blood and used blood treatment fluid. The fluid pumps are configured to pass blood treatment fluid through the blood treatment unit. The blood pumps are configured to extract untreated blood from a blood source, pass extracted blood through the blood treatment unit and deliver treated blood to a target vessel. Additionally, the fluid pumps are configured to control the operation of the blood pumps via the blood treatment fluid. Moreover, a flow control device is configured to control a trans-membrane flow between the blood side and the a fluid side of the blood treatment unit. Hence, for instance ultrafiltration can be adjusted to a desired level in a very straightforward manner.Type: GrantFiled: April 14, 2009Date of Patent: November 12, 2013Assignee: Gambro Lundia ABInventors: Lennart Jönsson, Olof Jansson, Mattias Holmer, Jan Sternby, Anders Nilsson, Per Hansson
