摘要： A pleated filter includes a filter base having folds that repeatedly form peak portions and valley portions and having a shape of a cylinder whose axial direction is a ridge line direction of the folds, and a reinforcing sheet disposed in a valley portion viewed from the inside of the shape of the cylinder. The reinforcing sheet includes a first reinforcing sheet located on a back side of a fold forming a projection toward the outer circumferential side of the shape of the cylinder and a second reinforcing sheet located in a spacing between adjacent folds forming projections toward the inner circumferential side of the shape of the cylinder. The first reinforcing sheet and the second reinforcing sheet are disposed apart from each other in a depth direction of pleats of the pleated filter.

摘要： The present invention is an integral multilayered composite membrane having at least one ultrafiltration layer made by cocasting or sequentially casting a plurality of polymer solutions onto a support to form a multilayered liquid sheet and immersing the sheet into a liquid coagulation bath to effect phase separation and form a multilayered composite membrane having at least one ultrafiltration layer. Asymmetric ultrafiltration layer exposes wider pore side to feed. Separation of viruses and proteins are carried out using hydrophilic polymers.

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.

摘要： The present invention provides a liquid filtration device with internal flow paths that facilitate the purging of air bubbles from the device. The device includes internal channels that collect bubbles from fluid entering the filtration device and more efficiently direct fluid to sweep bubbles from the device during operation. The present invention also provides for an automatic means to minimize fluid loss during a vent process.

摘要： Fluid treatment assemblies and elements may include a plurality of axially extending pleats and may be used to treat fluids, including gases, liquids, or mixtures of gases, and/or solids, in a crossflow mode of operation. For example, some fluid treatment assemblies and elements may be used to remove one or more substances from the fluid and may then function as separators, including filters and concentrators. Other fluid treatment assemblies and elements may be used to transfer substances between two fluid streams and may then function as mass transfer devices.

摘要： A filtration module is provided which includes a manifold, a filtration cartridge and a bowl that houses the filter cartridge. The filtration cartridge and bowl are connected to each other by a key and a mating keyway to form a unitary construction. The filtration cartridge and bowl are in fluid communication with the manifold in a manner which prevents mixing of a fluid feed to the module and a permeate removed from the module.

摘要： A porous fluorocarbon membrane comprising a porous support having the average pore size from 5,0 to 500,0 mcm and the difference by specific weight in one sample of 7,0% max., completely impregnated with copolymer containing 23 - 25 weight percent tetrafluoroethylene and 73 - 75 weight percent vinylidene fluoride and having the ratio of viscosity of the solution thereof in acetone to acetone equal to 2,0 - 4,0. A method for producing a porous fluorocarbon membrane comprising porous support having specified characteristics by dissolving tetrafluoroethylene / vinylidene copolymer in a readily-boiling solvent, mixing said solution with a precipitating mixture of alcohol and water to produce a casting solution, impregnating said porous support with heated casting solution and storing said support for a short time vor evaporating a portion of solvent and partial hardening of a casting solution followed by at least three-zone drying of the resulting membrane with the temperatures increasing from one zone to another in sequence. A cartridge filter comprising protective and supporting cylindrical perforated hollow housings, a pleated porous fluorocarbon membrane having specified design including a prefiltration device and a drainage, placed between said housings and tightly connected to the housing cases of the end caps. A cartridge filter comprises two said membranes superimposed such that membrane closer to the prefiltration device has the pore size ranging from 0,25 to 0,65 mcm, and second membrane has the pore size ranging from 0,15 to 0,45 mcm.
