摘要： A reduced pressure water filtration system provides for water filtration at a pressure lower than line pressure while preventing exposure of the reduced pressure water filtration system to potentially damaging static pressures such that the system and components are exposed to significantly less water pressure. The reduced pressure water filtration system can comprise a distribution module, at least one filter element, a filtered water storage module and a control unit. The filtered water storage module and the control unit may or may not be physically connected with the distribution manifold and/or filter element. A downstream side of the reduced pressure water filtration system is vented to atmosphere such that closing an inlet valve to the reduced pressure water filtration system in a non-flow mode results in any static pressure being vented.

摘要： An at least two zone, unsupported, continuous microporous membrane is disclosed. The at least two zone, unsupported, continuous microporous membrane may include at least two different membrane pore size zones or the pore sizes may have about the same pore size. Apparatus and processes for fabricating at least a two zone unsupported, continuous, microporous membrane are also disclosed. One representative process disclosed for forming a continuous, unsupported, multizone phase inversion microporous membrane having at least two zones comprises of the acts of: operatively positioning at least one dope applying apparatus, having at least two polymer dope feed slots, relative to a continuous moving coating surface; applying polymer dopes from each of the dope feed slots onto the continuously moving coating surface so as to create a multiple layer polymer dope coating on the coating surface; subjecting the multiple dope zone layer to contact with a phase inversion producing environment so as to form a wet multizone phase inversion microporous membrane; and then washing and drying the membrane. Other representative apparatuses and processes are also disclosed.

摘要： Systems and methods for the manufacture of reinforced, three-zone, microporous phase inversion membrane having any one of a plurality of different possible pore sizes in any of the three zones from at least a single mother dope batch is disclosed. The systems and methods include formulating at least a single mother batch of dope in a vessel preferably maximizing the non-solvent to solvent ratio for a given weight percentage of polymer for use in a microporous phase inversion membrane production operation to produce three-zone phase inversion membranes having one of a plurality of different predetermined pore sizes in any or all of the three zones. The at least one mother dope batch is controllably formulated in at least one vessel such that the temperature of the dope does not exceed a predetermined maximum mixing temperature and is maintained at a relatively low temperature (lower than the mixing temperature) suitable for storage. A small portion of the dope from the at least one mother batch is then heated to a temperature no higher than any one of a plurality of target temperatures, in at least one thermal manipulation apparatus, the target temperature corresponding to a specific desired pore size to be formed in at least one zone of the microporous phase inversion membrane that results from operations at a dope processing site. The dope is then cooled to about room temperature or the temperature which results in a suitable and/or optimal coating viscosity. At least one dope application apparatus is connected to the at least one thermal manipulation apparatus such that any one of a plurality of different pore size producing dopes from the thermal manipulation apparatus is transported to the dope processing site and applied to any one of the three-zones of the three-zone reinforced, microporous membrane being produced.

摘要： A cell-type filter unit having two or more filter media layers and/or zones, at least one of the layers/zones having a different particle retention capability disposed on each side of a non-filtering separator element. The filter media are preferably positioned such that each succeedingly distal filter layer or zone from the separator has a decreased particle retention capability than each proceeding filter layer or zone. The filter media layer most proximal to the separator element may be separated from the separator by a support material for supporting such filter media element and preventing collapsing of the media into any separator conduit.

摘要： A spiral wound filter element is disclosed which includes alternating layers of filter medium and diffusion medium wrapped about a cylindrical core defining a central axis of the filter element. The alternating layers extend from a radially innermost layer of the filter element to a radially outermost layer of the filter element, the diffusion medium is defined by a continuous lengthwise sheet of mesh material, and the filter medium is defined by at least one sheet of filter material arranged along the length of the continuous sheet of mesh material. The alternating layers of filter medium and diffusion medium define three distinct radially disposed layered filtering sections surrounding the cylindrical core, and include a first filtering section having radially outer prequalifying layers, a second filtering section having middle prequalifying layers and a third filtering section having radially inner qualifying layers. The radially outer prequalifying layers and the middle prequalifying layers define about two-thirds of the radial distance from the radially outermost layer of the filter element to the radially innermost layer of the filter element.

摘要： A cell-type filter cartridge has a plurality of cells (22,24) arranged co-axially and each having first and second filter media (44) with netting (42) stretched over the outer (unfiltered fluid) sides thereof. A plastics ring is moulded in position around and over the peripheries of the first and second filter media (44) and the netting. A separator (46) is centrally disposed between the media (44) of each cell to prevent the collapsing thereof, and inter-cell spacers (48) are positioned between adjacent cells, the spacers having sealing rings (50).

摘要： A method for retrieving excess pharmaceutical process fluid from the hold-up volume of a primary fluid filtration device. The hold-up volume is the volume of excess process fluid which accumulates in the bottom of the filter housing below the outlet opening thereof. Because it is considered valuable, the excess pharmaceutical process fluid is retrieved from the lower housing (22) via a drainage port (23) formed therein below the level of the outlet. The excess process fluid is then filtered in a supplemental filtration device (100) that is connected to the drainage port. The supplemental filtration device has a smaller volumetric capacity than the capacity of the primary fluid filtration device.

摘要： The media includes cellulosic fiber and silica based particulate or fiber filter elements and a charge modifying amount of a cationic charge modifying system bonded to the surfaces thereof. A component of charge modifying system is a primary charge modifying agent characterized as a water soluble organic polymer capable of being adsorbed into the filter elements and having a molecular weight greater than about 1000. Each monomer of the polymer can have at least one epoxide group capable of bonding to the surface of the filter elements and at least one quaternary ammonium group. A portion of the epoxy groups on the organic polymer are bonded to the secondary charge modifying agent. This secondary charge modifying agent is an aliphatic polyamine having at least one primary amine or at least two secondary amines.
