Patent number: 8911633Abstract: Fluid treatment arrangements and elements and methods for making and using fluid treatment arrangements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. Two or more fluid treatment elements may be positioned along a core assembly with spaces between at least some of the adjacent fluid treatment elements. Posts may be located in some of the spaces and may be bonded to the adjacent fluid treatment elements. Bands may encircle some of the spaces to block radial fluid flow into or out of the spaces.Type: GrantFiled: March 14, 2008Date of Patent: December 16, 2014Assignee: Pall CorporationInventors: Thomas Welch, Jr., Tanweer ul Haq, Joseph Verschneider

Patent number: 8640884Abstract: Fluid treatment arrangements and methods for making and using fluid treatment arrangements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. For some embodiments, the ribbon may comprise a composite having first and second layers. At least two and as many as many as fifty or more fluid treatment elements may be positioned along a core assembly with spaces between at least some of the adjacent fluid treatment elements. Many, most, or substantially all of the spaces may be substantially free of structure. A fluid treatment arrangement may be contained in a housing to form a fluid treatment assembly. The housing may include an inlet port and an outlet port and may define a fluid flow path between the inlet port and the outlet port. The fluid treatment arrangement may be positioned in the housing across the fluid flow path.Type: GrantFiled: March 14, 2008Date of Patent: February 4, 2014Assignee: Pall CorporationInventors: Thomas Welch, Jr., Tanweer ul Haq, Joseph Verschneider

Patent number: 8640885Abstract: Fluid treatment arrangements having at least first and second radially displaced sets (12,13) of fluid treatment elements and methods for making and using them are disclosed: A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element of either set. At least two and as many as fifty or more fluid treatment elements (14?, 14?) may be positioned along a hollow core assembly (11) in each set. Fluid may be directed to or from the interior of the core assembly through a fluid treatment element of the first set and a fluid treatment element of the second set. In each fluid treatment element, fluid flows generally edgewise through the permeable fluid treatment medium.Type: GrantFiled: March 14, 2008Date of Patent: February 4, 2014Assignee: Pall CorporationInventors: Thomas Welch, Jr., Tanweer ul Haq, Joseph Verschneider

Patent number: 8048315Abstract: Fluid treatment arrangements and methods involve a plurality of fluid treatment modules and a core assembly that extends through the plurality of fluid treatment modules. Each fluid treatment module has a feed region, a permeate region, and a fluid treatment medium separating the feed region from the permeate region. The feed region extends along a feed surface of the fluid treatment medium, and the permeate region extends along a permeate surface of the fluid treatment region. Feed fluid is directed along the feed region of each module, and a portion of the feed fluid passes as permeate through the fluid treatment medium, into the permeate region, and then into the core assembly. One or more control mechanisms are fluidly coupled to the permeate region of one or more fluid treatment modules to control a flow parameter in the permeate region of the module.Type: GrantFiled: July 28, 2008Date of Patent: November 1, 2011Assignee: Pall CorporationInventors: Thomas J. Fendya, Xianyao Shen, Tanweer ul Haq, Mark F. Hurwitz, Stephen A. Geibel

Patent number: 8043512Abstract: Fluid treatment arrangements and methods involve a spirally wound fluid treatment pack. The fluid treatment pack includes a fluid treatment medium, a feed region, and a permeate region. The feed region extends along a feed surface of the fluid treatment medium and the permeate region extends along a permeate surface of the fluid treatment medium. The fluid treatment pack is spirally wound around a core assembly to form a plurality of windings of the feed region, a plurality of windings of the fluid treatment medium, and a plurality of windings of the permeate region.Type: GrantFiled: April 11, 2008Date of Patent: October 25, 2011Assignee: Pall CorporationInventors: James A. Bair, Thomas J. Fendya, Mark F. Hurwitz, Tanweer ul Haq, Stephen A. Geibel

Publication number: 20100219139Abstract: Fluid treatment arrangements and methods for making and using fluid treatment arrangements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. The disk-shaped body may include opposite end surfaces, an inner rim, and an outer rim. Up to one hundred or more fluid treatment elements may be positioned along a core assembly, and a surround may be positioned around the fluid treatment elements. The fluid treatment elements may be sealed to the core assembly with the inner rims covering openings in the core assembly, or the fluid treatment elements may be sealed to the surround with the outer rims covering openings in the surround. A fluid treatment arrangement may be contained in a housing to form a fluid treatment assembly. The housing may include an inlet port and an outlet port and may define a fluid flow path between the inlet port and the outlet port.Type: ApplicationFiled: March 14, 2008Publication date: September 2, 2010Applicant: PALL CORPORATIONInventors: Thomas Welch, Jr., Tanweer ul Haq, Joseph Verschneider

Publication number: 20100206819Abstract: Fluid treatment arrangements and elements and methods for making and using fluid treatment arrangements and elements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. The disk-shaped body may have first and second opposite end surfaces, e.g., an inflow surface and an outflow surface, and an outer rim. One or both of the end surfaces may be an uneven surface. At least two and as many as many as fifty or more fluid treatment elements may be positioned along a hollow core assembly. Fluid may be directed to or from the interior of the core assembly through each fluid treatment element. In each fluid treatment element, fluid flows from the inflow surface to the outflow surface generally edgewise through the permeable fluid treatment medium.Type: ApplicationFiled: March 14, 2008Publication date: August 19, 2010Applicant: PALL CORPORATIONInventors: Thomas Welch, JR., Stephen Geibel, Tanweer ul Haq
