摘要:
A device, which is suitable for the processing of at least one fluid, is provided with at least one elongated foil, which is formed in a number of reciprocating foil layers. Between two opposite layers of foil, a spacer is situated 5 that is permeable at least parallel to the foil layers. The foil layers and interposed spacers extend spirally around a central axis, wherein folding lines between two foil layers extend substantially parallel to the central axis. Each spacer is coupled to at least an end near the central axis with a support extending parallel to the central axis where, of the supports near the central axis, first supports are situated between 10 two foil layers, which foil layers are connected to one another near the central axis, whereas second supports are situated between two successive first supports.
摘要:
A water filtration device and method in which water is pumped through a chamber (513) containing iron oxide particles or material (750), which allows removal of ionic contaminants, including fluoride. Water is then pumped through a plurality of ultrafilration tubes (632, 521). The water enters the sides of the tubes into the tube interior and flows out of the open ends of the tubes. The sides and the ends of the tubes are separated by a water impermeable barrier (22).

A filter module for fluids, comprising a pleated filtering membrane (6) the surface of which separates a pre-filtration volume, upstream of the filtering membrane (6), from a post-filtration volume, downstream of the filtering membrane (6), said pleated filtering membrane (6) presenting, on its surface, pleats bounded by contiguous crests (7), said filtering membrane comprising, on the pre-filtration volume side, a conveyor (10) for causing the filtrate to flow substantially between the pleats of the pleated filtering membrane (6).
摘要:
An encapsulated filter cartridge is disclosed, which includes a filter assembly including a carbon block filter element and a microporous filter element. The filter cartridge has a permanently sealed sump defining an interior chamber configured to accommodate the filter assembly, the sump having an inlet for permitting unfiltered fluid to enter the interior chamber for communicating with the radially outer surface of the filter assembly and an outlet for permitting filtered fluid to exit the interior chamber from the axial portion of the filter assembly. The microporous filter element of the filter assembly may include a hollow fiber subassembly housed within the axial cavity of the carbon block element, said fiber subassembly including a plurality of hollow microporous fibers, or a pleated filter element surrounding the radially outer surface of the carbon block element.

A filtration module (1) is provided which includes a manifold (3), a filtration cartridge (50) and a bowl (2) that houses the filter cartridge (50). The filtration cartridge (50) and bowl (2) are connected to each other by a snap fit construction (22) to form a unitary construction. The filtration cartridge (50) and bowl (2) are in fluid communication with the manifold (3) which prevents mixing of a fluid feed to the module (1) and a permeate removed from the module (1).
摘要:
A filter element (10) comprising a hydrophilic organic polymeric microporous filter membrane (12) having a preformed substantially non-porous sealing area (16) and a filter housing (14) having, preferably, a hydrophilic thermoplastic sealing surface in thermoplastic sealing relationship with the sealing area (16). Preferably, the filter element (10) comprises a hydrophilic nylon microporous filter membrane (12) having a performed substantially non-porous sealing area (16) of non-porous tape (16) heat sealed to the membrane (12) and a filter housing (14) having a hydrophobic thermoplastic sealing surface in thermoplastic sealing relationship with the sealing area (16). The filter membrane (12) is preferably a pleated cylindrical membrane and the housing (14) includes endcaps (32, 34) thereto. The preferred cylindrical membrane (12) is produced from an elongated porous filtration area longitudinally bordered by substantially non-porous sealing areas (16). Such a membrane may be produced by a specific casting method or collapsing the pores along the longitudinal borders of the filtration area. Additionally, such a membrane (12) may be produced by applying a heat sealable non-porous tape (16) along the longitudinal borders of the filtration area. The filter element (10) is particularly useful for the filtration of aqueous liquids, particularly parenteral or body liquids.
