Membrane filtration module

Provided is an improved filtration module assembly comprising a vessel having a filtration cartridge disposed within it and a header coupled to an end of the vessel, the header including a housing having an open-ended upper end and a lower end, and an end cap including a portion that mates with a complimentary structure defined by the inner all of the open ended upper end of the housing to removable engage with the housing and the end cap may further define a passageway for fluid to flow out of the vessel. The filtration module assembly may enable an improved manifold arrangement used to communicate fluids to and from a filtration system comprising a plurality of such modules and the configurations of the present invention may facilitate improved operation of such filtration systems.

Manifold arrangement

Disclosed herein are aspects and embodiments of an apparatus for securing hollow fiber filtration membranes in a filtration module. In one example, the apparatus comprises a restraining structure engaging elongate portions of the plurality of hollow porous membrane fibers and an anchor formation engaging the plurality of hollow porous membrane fibers and positioned closer to eye portions of the plurality of hollow porous membrane fibers than at least a portion of the restraining structure. Neither the anchor formation nor the restraining structure sealingly engage open ends of the plurality of hollow porous membrane fibers.

Membrane securement device

Provided is an improved filtration module assembly comprising a vessel having a filtration cartridge disposed within it and a header coupled to an end of the vessel, the header including a housing having an open-ended upper end and a lower end, and an end cap including a portion that mates with a complimentary structure defined by the inner wall of the open ended upper end of the housing to removably engage with the housing and the end cap may further define a passageway for fluid to flow out of the vessel. The filtration module assembly may enable an improved manifold arrangement used to communicate fluids to and from a filtration system comprising a plurality of such modules and the configurations of the present invention may facilitate improved operation of such filtration systems.

Disclosed herein are aspects and embodiments of filtration membrane modules including porous membranes and methods and structures associated with potting ends of the porous membranes in the membrane modules. In one example, there is provided a method of forming a filtration module. The method comprises securing a portion of a porous membrane in a pre-pot, positioning at least a portion of the pre-pot in a potting mold, introducing a pot forming substance into the potting mold, the pot forming substance surrounding at least a portion of the pre-pot and at least a portion of the porous membrane, curing the second pot forming substance to form a membrane pot, and separating the membrane pot from the potting mold.

Filtration assembly

A module arrangement () according to an embodiment of the invention consists of a plurality of membrane modules () arranged in a two dimensional array () and extending between upper and lower block-type manifolds () and (), respectively. The array of modules is further divided into sub-groups of modules () separated from each other by space () extending transversely across the membrane array (). An integrated support frame () is positioned in the space () between the sub-groups () and is fixed to the upper and lower manifold blocks () and () to form an integrated support structure within the module array ().

Frame system for membrane filtration modules

A method and apparatus for removing fouling materials from the surface of a plurality of porous membranes () arranged in a membrane module () by providing, from within the module, by means () other than gas passing through the pores of said membranes, gas bubbles in a uniform distribution relative to the porous membrane array such that the bubbles move past the surfaces of the membranes () to dislodge fouling materials therefrom. The membranes () are arranged in close proximity to one another and mounted to prevent excessive movement therebetween. The bubbles also produce vibration and rubbing together of the membranes to further assist removal of fouling materials.
