Patent number: 7309429Abstract: The invention is a granular media filter for in-line liquid applications that allows media as fine as 44 micron to be used to increase the removal of contaminants from the liquid with adequate flows consisting of a specific arrangement. A flow distributor has a non-woven fiber web welded to it; followed by a mixture of fine particle media (finer than 20×50 mesh); followed by a compressible chlorine resistant open cell polyurethane foam, then a 5 micron rated meltblown fiber tube attached to the outlet end by melt adhesive on one end and closed with a plastic plug on the other end. The foam can be either polyurethane or polyolefin, and it can be either open cell foam, or reticulated and open cell foam. A preferred embodiment includes within the fine particle media 10% by weight of flow-enhancing antimicrobial plastic pellets, about 4-5 mm in diameter and having an aspect ratio of 2-3, the pellets encapsulating an antimicrobial additive.Type: GrantFiled: January 25, 2006Date of Patent: December 18, 2007Assignee: Ricura Technologies, LLCInventors: Arvind S. Patil, Glenn F. Cueman

Patent number: 7303682Abstract: The present invention relates to a fluid distributing device for distributing fluid into a column and to a fluid collecting device for collecting fluid from a column. The invention relates also to methods of using the devices of the present invention. The distributing device and/or the collecting device of the present invention can be used in fixed or fluidized bed reactors or columns, such as chromatographic separation columns, ion exchange columns, adsorption columns etc. A fluid distributing device comprises a) a first fluid conveying system; and b) a distributing plate, which comprises i) first means for fluid transfer for dividing the fluid flow coming from the delivering points into several partial fluid flows and for distributing the partial fluid flows into the column; and ii) first means for controlling of the partial fluid flows by differential pressure in the first means for fluid transfer.Type: GrantFiled: December 13, 2005Date of Patent: December 4, 2007Assignee: Finnfeeds Finland OYInventors: Hannu Paananen, Heikki Heikkilä, Jari Lewandowski, Esko Varteva

Patent number: 7288194Abstract: An underdrain system having a bottom formed of concrete. The concrete bottom includes a plurality of depressions formed therein. A porous plate is operably associated with at least one of the depressions. An anchor assembly is provided for anchoring the porous plate to the concrete bottom in an efficient and cost effective manner. Preferably, the anchor assembly permits the porous plate to be readily replaced. An optional insert may be used to enhance the distribution of the flow of fluid through the porous plate.Type: GrantFiled: January 20, 2006Date of Patent: October 30, 2007Assignee: RG Deleware, Inc.Inventors: R. Lee Roberts, Mark Kevin Addison

Patent number: 7267770Abstract: A radial flow cartridge, especially for use with an ion exchange resin, includes inner and outer tubular cages, and a tubular knitted liner extending the length of the cartridge between the inner and outer cages and spaced apart from the outer cage. The resin medium fills the space between the liner and the inner cage. During use, the medium absorbs fluid and expands, stretching the knit liner radially and, thereby filling the space between the liner and the outer cage.Type: GrantFiled: October 9, 2003Date of Patent: September 11, 2007Assignee: The Hilliard CorporationInventors: Leslie R. White, Douglas Smith
