| 20080210623 | Square Mbr Manifold System - A membrane module ( | 09-04-2008 |
| 20080230470 | Filter Module and Process for Manufacture of Same - The present invention provides a filter module comprising a body of wound layers of a sheet material, said sheet material having a plurality of openings formed therein, said openings forming two types of channels within the wound layers of sheet material of said body, said channels extending in a direction from the inner peripheral surface to the outer peripheral surface, a first type of channels being open at one end at said outer peripheral surface of the body and closed at the other end located adjacent to said inner peripheral surface, a second type of channels being open at one end at said inner peripheral surface of the body, and closed at the other end located adjacent to said outer peripheral surface, said channels of the one type being separated from the channels of the other type by portions of sheet material, wherein the surface of at least one type of the channels supports a precoat and a process for the manufacturing of such a filter module. | 09-25-2008 |
| 20100206801 | FILTERING BASKET FOR FIBRES IN WATER DISPERSION - The invention is a filtering basket for fibres in water dispersion, comprising a plurality of profiled bars arranged side by side to define a tubular structure with the inner lateral surface provided with a plurality of longitudinal slots that define a filtering surface; two or more annular elements coaxial to one another and spaced from one another, coupled by interference outside the profiled bars. The profiled bars comprise a plurality of main bars, each one of which is provided with a shaped edge whose cross-section is in the form of a trapezium and has the long side facing towards the inside of the basket and a plurality of secondary bars, each one of which is provided with a shaped edge whose cross-section is curved, with the convex part facing towards the inside of the basket. | 08-19-2010 |
| 20120012518 | CORELESS FILTER CARTRIDGE AND METHOD OF FORMING A CORELESS FILTER CARTRIDGE - A coreless filter cartridge includes a filtration media having a plurality of pleats formed in a tubular configuration. The filtration media includes a first end that extends to a second end through an intermediate portion having an exterior surface and an interior surface that defines a hollow core. At least one retention device is adhered to the exterior surface of the filtration media. The at least one retention device is configured and disposed to limit radial movement of the filtration media. The filter cartridge is devoid of an internal core support provided within the hollow core thereby establishing a coreless filter cartridge. | 01-19-2012 |
| 20130008847 | FILTERING ELEMENT AND METHOD FOR ITS MANUFACTURE - The disclosed subject matter is concerned with a screen-type filter element, and a method for its manufacture. The screen type filter comprises a substantially rigid screen-bearing skeleton and at least one fine screen sheet material extending within or over the skeleton and secured thereto by a plurality of enveloping ribs, the enveloping ribs being applied over one face of the filter screen sheet to thereby support it at discrete portions and secure it to the skeleton. | 01-10-2013 |
| 20130146528 | FILTER ELEMENT FOR FILTERING FLUIDS - The invention relates to a filter element for filtering fluids, comprising a flat support structure which forms the wall of a support tube ( | 06-13-2013 |
| 20130161253 | REINFORCEMENT ELEMENT - The present disclosure describes a means to provide structural reinforcement for spiral wound membrane elements. The reinforcement includes a wire and, optionally, an outer wrap. The wire is wrapped around an outer layer of the spiral wound membrane layer and reinforces the spiral wound membrane element. The wire is made from materials that do not deform substantially during sanitization procedures. The outer wrap is wrapped around the wire and limits unsanitary areas of tight tolerance between the perimeter of the spiral wound membrane element and a housing. | 06-27-2013 |
| 20130306547 | PLEATED FILTER MEDIA WITH CONTINUALLY VARYING INTERMEDIATE PLEAT HEIGHTS - Pleated filtration media and filtration devices generally include a filter media radially disposed about the annular perforated inner core, the filter media comprising a plurality of circumferentially disposed linear pleats extending from the inner core to a constant height (h) defined by an outer diameter; and one or more intermediate pleats circumferentially disposed between adjoining linear pleats, wherein each one of the intermediate pleats has a height less than the constant height, and wherein the height of the intermediate pleats progressively decreases in a clockwise or a counter clockwise direction. Also disclosed are methods for increasing surface area of a pleated filtration media. | 11-21-2013 |
| 20140197093 | FILTER SEGMENT WITH A LIGHT WEIGHT FRAME - A disc segment adapted to be attached to other disc segments to form a disc assembly, the disc segment including an isosceles trapezoid frame. The frame comprises a left side rail and a right side rail, and a plurality of spaced apart parallel horizontally extending ribs connected between the side rails. The frame defines a first disc side and an opposite second disc side, each disc side including a corrugated left bottom clamp list adjacent the left side rail and supported by the ribs, and a corrugated right bottom clamp list adjacent the right side rail and supported by the ribs. Each disc side also includes a corrugated wire mesh supported by the left and right clamp lists, and supported by the frame ribs. | 07-17-2014 |
| 20150096933 | Filtration Article Having Thermoplastic Filled Edges - A filtration article and a method for manufacture of the filtration article. The filtration article includes a filtration medium that includes a porous membrane. A thermoplastic end cap component is potted onto the filtration medium along the peripheral edge of the filtration medium. To enhance the quality of the seal between the end cap component and the filtration medium, a thermoplastic material is imbibed through at least a portion of the thickness of the filtration medium along the peripheral edge. Methods for the manufacture of such a filtration article and the filtration medium are also provided. | 04-09-2015 |
