20090071892 | FILTER CARTRIDGE - A filter cartridge that is designed to accommodate differences in lengths between an outer filter media and an inner filter media by providing a flexible connection between the inner filter media and the outer filter media. In addition, the endplates of the inner filter and the outer filter together define a gasket groove that receives a gasket. Using the endplates of the inner and outer filter media to define the gasket groove eliminates a mold parting line that can lead to fluid leakage. | 03-19-2009 |
20090159521 | METHOD AND APPARATUS RELATED TO LIQUID FILTRATION SYSTEMS - A filtration module comprises a housing having an inlet and an outlet; a plurality of hollow fiber membranes disposed in the housing, each membrane having a wall and a lumen open to the outlet; a porous shell disposed in the housing and encasing the plurality of hollow fiber membranes, the shell having an opening through which ends of the hollow fiber membranes pass; and a plug in the outlet, the ends of the hollow fiber membranes passing through the plug and the shell ending in the plug. A liquid treatment apparatus comprising the filtration module is also disclosed, as are method for making the filtration module and the liquid treatment apparatus. | 06-25-2009 |
20090321343 | Dual body drum for rotary separators - A drum is for a rotary separator including a shaft rotatable about a central axis. The drum includes an inner drum member having inner and outer circumferential surfaces and being disposed generally about the shaft such that a first flow passage is generally defined between the inner drum member inner surface and the shaft. The inner drum inner surface is configured to separate liquids from a fluid flow contacting the surface. An outer drum member has inner and outer circumferential surfaces and is disposed generally about the inner drum member such that a second flow passage is generally defined between the outer drum member inner surface and the inner drum member outer surface, the second flow passage being generally coaxial with the first flow passage. Further, the outer drum inner surface is also configured to separate liquids from a fluid flow contacting the surface. | 12-31-2009 |
20100219117 | COALESCING ELEMENT - A filter element includes a cylindrical housing enclosing a ring-shaped filter media assembly. The media assembly includes inner and outer media rings, moveably supported relative to one another, to remove particulate matter and water from a fluid stream. The outer ring surrounds the inner ring and is sealed by a first seal to the housing. An end cap assembly at the upper end of the element includes an annular end cap piece attached to an upper end of the inner ring, a flat plate, and a threaded flange portion bounding the periphery of the plate. A second seal is provided between the upper end cap of the inner ring, and an upper end cap of the outer ring. The housing is secured to the media assembly by forming an open end of the housing around the flange portion. | 09-02-2010 |
20100276354 | Systems and methods for removing contaminate material from a flowable material - A tank assembly for holding first and second removal materials, comprising a first container and a second container. The first container defines a first chamber. The second container defines a second chamber. The second container is arranged within the first chamber to define a lower portion, an upper portion, and an annular portion of the first chamber. The second chamber comprises a lower portion and a filter portion. The filter portion of the second chamber is adapted to contain the first removal material. The annular portion of the first chamber is adapted to contain the second removal material. | 11-04-2010 |
20100282661 | FLUID TREATMENT SYSTEM - There is described a fluid treatment system comprising: (i) a fluid inlet; (ii) a fluid outlet; and (iii) a fluid treatment zone in fluid communication with the fluid inlet and the fluid outlet. The fluid treatment zone comprises a housing within which is disposed a fluid separation section (the separation section may include a single separation device or a combination of two or more similar or disimilar separation devices) and a fluid radiation section in fluid communication with one another. The fluid separation section removes solids in the fluid and the fluid radiation section irradiates the fluid to deactive microorganisms in the fluid. The fluid separation section and the fluid radiation section are configured to have a substantially common fluid flow path which significantly reduces the space or footprint requirement of and/or significantly reduces hydraulic head loss (pressure drops) in the overall fluid treatment system while allowing the two sections to perform their respective functions. | 11-11-2010 |
20140158604 | Platelet Storage Container - Compositions, methods, devices and media are provided for platelet storage container that prevents bacterial growth in the stored platelets. The invention relates to blood bank needs in safely storing platelets collected from donors for more than 5 days at room temperature. The container is built with natural adsorbent media that have the characteristics in capturing and killing bacteria and viruses. The stored platelets are isolated from the natural adsorbent material during storage to preserve their medical quality and safety. | 06-12-2014 |
20140311962 | Water Filter System - A slow/intermittent sand filter that purifies polluted water by flowing through sand in a manner that achieves greater purity and permits simpler and more effective maintenance than existing filters. | 10-23-2014 |
20150041383 | WATER CONTAINER - A container ( | 02-12-2015 |
20160038855 | PHASE SEPARATION TANK - A separation tank for separating a contaminant from a contaminated fluid. A series of juxtaposed interconnected chambers having a series of baffles therein provide a revolving flow of fluid in each chamber to maximize distance for which contaminants travel to separate from the fluid. The interconnected chambers may be juxtaposed in end-to-end relation or in side-by-each configuration. | 02-11-2016 |
