摘要:
Described are porous filter membranes that include two opposed sides, a thickness, and a porous structure between the opposed sides; filter components and filters that include this type of porous filter membrane; methods of making the porous polyethylene filter membranes, filter components, and filters by co-extrusion techniques; and methods of using a porous filter membrane, filter component, or filter as described.
摘要:
A corrugated membrane plate and frame module for use in fluid treatment applications is disclosed, where the corrugated design increases production capacity of a module by more than 200% as compared to conventional modules. The increase is achieved by tripling the membrane packing density per module using an optimized corrugated design. The disclosed corrugated membrane plate and frame also reduces the inactive membrane area per module, which is caused by deactivation of membranes edges attached to the plate and frame core in order to prevent leakage.

Pleated, tapered, and spiral-wound cross-flow filter elements (100) are described. The filter elements have pleated and tapered membrane leaves (110). The pleated and tapered membrane leaves maintain retentate fluid velocity in high permeate flux applications.

A microfiltration filter, an assembly containing such a filter and a method of manufacturing such a filter is provided. In one embodiment the method comprises folding a sheet of woven fibre filtration material onto itself, thereby providing an elongate double sheet of filtration material having two substantially parallel planar sides with aligned edges. The double sheet has open and blind long edges and two short opposing open edges. The method includes positioning an elongate collection manifold between the sides at least partway along and at or near the blind edge, providing a fluid outlet in at least one of the sides wherein the fluid outlet is in fluid communication with an interior of the collection manifold. The method further includes sealing the open long edge and short edges of the double sheet to form a liquid impervious seal and a planar, elongate collection chamber between the sides, and folding the elongate collection chamber across the long edges to create a filter with multiple adjacent layers of the planar, elongate collection chamber.

The present disclosure relates to modular purification systems using removable purifier cassettes for purifying liquids including, for example, liquids used in semiconductor manufacturing. A purification system may include a removable purifier cassette having a purifier inlet port and a purifier outlet port, and a manifold assembly. The manifold assembly can include a plurality of connection systems to that provide manifold ports to provide fluid to/from the cassette. In some embodiments, the connection systems may use connection nuts that can provide 360 degrees of thread engagement with less than 360 degrees of rotation.
