Description

    TECHNICAL FIELD
  • The present invention relates to membrane filtration manifold systems. More particularly the invention relates to membrane filtration manifold systems for hollow fibre membrane filters comprising elongate bundles of hollow fibre membranes, wherein feed to be filtered is fed to the outside of the bundles of fibres and filtrate is extracted from the end or ends of the fibre lumens. The systems also preferably incorporate a cleaning facility for periodic cleansing of the feed surfaces of the fibres. [0001]
  • The invention has been developed primarily for use in a membrane filtration system which is open to atmospheric pressure and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use. [0002]
  • BACKGROUND ART
  • Typical prior art filtration manifolds are employed in filtration systems of the type described above. These filtration systems generally include elongate tubular cartridges enclosing a bundle of the hollow fibre membranes. Manifold or header arrangements are used to connect the cartridges, usually at one or both ends, these manifolds acting to separate and divert the respective flows of the contaminated feed. filtrate and cleaning fluid through the system. In this regard, cross-flow systems typically have two feed manifolds (inlet and re-circulation outlet) and one or two filtrate manifolds. In cross-flow filtration systems of the prior art the feed stream to be filtered flows tangential to or across the surface of the membrane. This generates a sweeping action at the membrane surface, keeping the surface cleaner. Conversely, systems configured for dead end operations utilise only one feed inlet manifold and one filtrate outlet manifold during filtration mode. Further, these prior art manifolds or header arrangements are often configured to facilitate the construction of modular two or three dimensional cartridge arrays. [0003]
  • Most typically, the prior art filtration systems, as previously described, are closed to the atmosphere. In such systems, fluid to be filtered, hereinafter referred to as feed, is fed under positive pressure to the filters. In order for this type of system to operate effectively, the elongate tubular filtration cartridges are encased in pressure tight housings. Such housings are then connected to a manifold system which both separates the feed from the filtrate and supports the pressure tight housing. The manifold system may also serve to introduce cleaning fluid to the filtration system. [0004]
  • Prior art filtration systems, as previously described, may also be open to the atmosphere. Typically in such systems, feed is drawn through the membranes under negative pressure. This is achieved by applying a negative, or suction, pressure on the filtrate side of the membrane. Such systems tend to employ less infrastructure and capital works compared with systems closed to the atmosphere as they do not require components that are able to contain relatively higher pressures. For example, there is no need to encase filtration cartridges in individual pressure tight housings in systems open to atmosphere. Typically in these systems, the filtration cartridges are merely substantially immersed in an open tank containing the feed. In such systems it is desirable that an appropriate manifold be provided to both support the filter cartridges and to allow the filtrate to be drawn from the filter while separating the feed from the filtrate. Similarly, as with closed systems, such a manifold may also serve the purpose of supporting a cleaning fluid system. [0005]
  • Prior art filtration systems and their associated filtration cartridges referred to above are often a complex configuration of pipes and parts which are difficult and time consuming to assemble. Further more, the actual manifold system components of the prior art filtration systems are often a complex assembly of parts in themselves. [0006]
  • The prior art filtration systems described above also require regular testing to assess system integrity. Non-integrity may be due to failure of individual filtration membrane hollow fibres, ‘o’-rings or other system components. Integrity testing often requires the removal of either individual system components or filtration cartridges. This removal is often difficult in typical prior art filtration manifolds. Furthermore, as previously discussed, typical prior art filtration manifolds may contain many complex parts. It then follows that integrity testing of these parts can also be time consuming. [0007]
  • It is an object of the present invention to provide a filtration manifold system of the kind herein described which overcomes or ameliorates at least some of the deficiencies of the prior art or at least offers a useful alternative thereto. [0008]

  • PREFERRED EMBODIMENTS OF THE INVENTION
  • Referring to the drawings, the membrane filtration manifold system includes a membrane filtration manifold [0053] 1 for connecting filter submodules 2 of the kind comprising elongate bundles of hollow fibre membranes. As best shown in FIGS. 1 and 2, the preferred embodiment of the manifold includes a housing 3 connected with four submodule connecting collars 4.
  • Referring to FIG. 3, the collars [0054] 4 are adapted to receive and locate submodules 2 having a connecting sleeve 5 with a locking flange 6. In this embodiment, the submodule 2 can be secured at one end with its respective collar 4 by a clip 7 which simultaneously engages the submodule 2 and locking flange 6 to prevent axial withdrawal of the submodule 2 from the collar 4. The locking flange 6 further engages bearingly with a lip 8 of the collar 4. Engaging and releasing the clip 7 enables substantially simple respective assembly and removal of the submodules 2 from the manifold 1. The manifold 1 further includes filtrate passageways 9 for fluid communication between the housing 3 and collars 4 and cleaning fluid passageways 10 for cleaning fluid communication with a cleaning fluid conduit 11.
  • FIGS. 4[0055] a, 4 b and 5 show the preferred embodiment of the clip 7. The clip 7 has a substantially cylindrical sidewall 12 with a top and bottom flange 13 and 14, each of which projects radially inwardly from the sidewall 12. The clip 7 is split in a line parallel to the central axis of the submodule 2 to allow radial expansion of the clip when slid axially into and out of locking engagement with the collar 4. Radial expansion is achieved by manually parting a pair of projections 40 provided on the top flange 13 of the clip, on either side of the split respectively. Furthermore, the clip 7 is resiliently biased to enable radial contraction of the clip when the clip snap-lockingly engages with both the submodule 2 and collar 4. When the clip is employed to engage both the submodule and the locking flange, bottom flange 14 locks over the submodule flange 6 and top flange 13 bearingly engages with the lip 8. Furthermore, the collar 4 has a stepped seat 15 for locking engagement with top flange 13.
  • FIG. 4[0056] c shows an alternate embodiment of the clip 7. This embodiment has additional projections 41 to aid in the manual removal of the clip 7 from both the submodule 2 and collar 4. The additional projections 41 extend radially from the sidewall 12 of the clip 7, on either side of the split of the sidewall 12.
  • FIGS. 7[0057] a-c and 8 a-c show embodiments of the submodule connection sleeves 5. These Figures show detail of the flange 6 and ‘o’-ring seat channel 17 features of the connection sleeves 5. One side 18 of the flange 6 is for bearing engagement with the collar 4 and a second side 19 is for locking engagement with the clip 7. Further, the embodiment of the submodule connection sleeve 5 shown in FIGS. 7a-c, has one channel 17 for use as an ‘o’-ring seat, while the embodiment of the submodule connection sleeve 5 shown in FIGS. 8a-c, has two channels 17 for use as ‘o’-ring seats.
  • The manifold [0058] 1 may also include a removable cap 20, for fluid-tight sealing engagement with the housing. The preferred embodiment of the cap, shown in FIGS. 9a and 9 b, includes a disc 21 with an axially extending threaded shaft 22 mounted to its centre on one side. The disc 21 also has projections 23 on the other side to facilitate manual turning of the cap 20. The cap will be described in more detail below.
  • A radially spaced flange [0059] 24 extends axially outwardly from the cap 20 on the same side of the cap as the shaft 22. This flange allows fluid tight sealing engagement of the cap 20 with the housing 1. FIG. 10 shows the preferred embodiment of the cap 20 in use.
  • In another embodiment of the invention shown in FIG. 11, a membrane filtration apparatus [0060] 25 includes a headpiece 26 and a basepiece 27, each being an embodiment of the membrane filtration manifold 1 as described above, and connected to four membrane filter submodules 2. Each headpiece 26 connects to a filtrate conduit 28 allowing fluid communication between each headpiece 26 and the filtrate conduit 28. The cap 20 is not required when the membrane filtration manifold 1 is used as a headpiece 26. Absence of the cap 20 allows fluid communication between the manifold 1 and the filtrate conduit 28.
  • Further, as seen particularly in FIGS. 12[0061] a and 12 b, each basepiece 27 is connected to a cleaning fluid conduit 11 allowing fluid communication between each basepiece 27 and the cleaning fluid conduit 11. When the membrane filtration manifold 1 is used as a basepiece 27, the threaded shaft 22 of the cap 20 is threadedly engaged with a corresponding bore on the cleaning fluid conduit 11. Also, in the preferred embodiment, the clip 7 is not required to lock the submodule 2 to the basepiece. This is because the submodule 2 will be held in its respective collar 4 of its basepiece 27, both by gravity and by virtue of the top of the submodule being held in place in its headpiece 26 and a clip 7.
  • In an alternate embodiment of the invention, the shaft [0062] 22 is hollow with an internal threaded portion. In this embodiment, rather than threadedly engaging with a bore in the cleaning fluid conduit, the shaft 22 internally threadedly engages with a complementary shaft projecting in a perpendicular direction from the cleaning fluid conduit 11.
  • In another embodiment of the invention, a membrane filtration apparatus bank [0063] 29 includes a plurality of membrane filtration apparatus 25 as described above wherein each headpiece 26 is connected to a filtrate conduit 28 and each basepiece 27 is connected to a cleaning fluid conduit 11. Additional stiffening elements 30, as shown in FIG. 11, may also be provided therebetween to aid physical stability of the filtration system. Typically, there are eight membrane filtration apparatuses 25 in each bank 29 and the apparatuses are arranged in an upright position. When employed in a filtration system, the bank 29 is substantially immersed in the feed, where the feed is contained in a tank 31 with an open top.
  • Preferably, air is used as the filtration submodule cleaning fluid which flows through the cleaning fluid conduit [0064] 11. As best shown in FIGS. 11, 12a and 12 b, the cleaning fluid conduit 11 is proximally above the basepieces 27 and lies in a straight line along the length of the bank 29 in between the collars 4. This allows the cleaning fluid conduit 11 to supply air to the basepieces 27 through a plurality of passageways 10 on the under side of the cleaning fluid conduit 11. Supplying air to the basepieces 27 through the underside of the cleaning fluid conduit 11 allows controlled release of the cleaning air, ensuring it is evenly distributed along the entire length of the bank 29.
  • In another embodiment of the invention, the filtration system includes a membrane filtration apparatus array as shown in FIGS. 11 and 13 having a plurality of apparatus banks [0065] 29 wherein each of the filtrate conduits 28 are connected to an array filtrate conduit 32.
  • The filtration apparatus banks [0066] 29 are further adapted for relatively simple disconnection from the membrane filtration apparatus array. When disconnected, the filtration apparatus banks may be removed from the membrane filtration apparatus array by lifting the bank vertically from the array. Similarly, the banks may also be placed individually into an array by lowering the banks vertically into its predetermined position. This allows for less complicated assembly and disassembly of the arrays and convenient access to submodules disposed in or near the centre of the array.
  • In a further embodiment of the invention, a membrane filtration array train, as best shown in FIG. 15, includes a plurality of membrane filtration apparatus arrays from FIG. 14 wherein the array filtrate conduits [0067] 32 are connected by a train conduit 33 such that the array filtrate conduits 32 are in fluid communication with the train conduits 33.
  • During filtration the tanks [0068] 31 are continuously substantially filled with feed which in turn submerges the arrays of filter submodules 2. Pumps 34 draw the feed through the filter submodules 2 producing filtrate. The filtrate under negative pressure from the pumps 34, travels through the manifolds 1, via the filtrate conduits 28, array filtrate conduits 32, and train filtrate conduits 33 and on to the pump. The filtrate then leaves the pump and also the filtration system via a filtrate exit conduit 35.
  • Although the invention has been described with reference to specific examples and to filtration manifolds used in filtration systems open to atmosphere, it will now be appreciated by those skilled in the art that the invention may be embodied in many other forms including filtration manifolds used in filtration systems closed to atmosphere.
