Abstract

The instant application relates to a high pressure spiral-type hollow fiber membrane fabric-containing module or contactor, comprising: a high pressure module housing or vessel; a pair of end caps; liquid end ports and at least one gas port; and at least one membrane cartridge, wherein each module or contactor has one or more shims, spacers, protrusions, and/or the like on a cartridge shell exterior, on a module housing interior, on the cartridge shell exterior and on the module housing interior, and/or between the shell and the housing.

First claim

The invention claimed is:

1. A degassing module comprising:
a housing enclosing a cartridge;
the cartridge comprising a shell having a first end, a second end, and enclosing a plurality of hollow fibers, each of the hollow fibers having an exterior surface and a lumen;
an end port in fluid communication with the exterior surfaces of the plurality of hollow fibers, and a side port in fluid communication with the lumens of the plurality of hollow fibers;
the plurality of hollow fibers having a shell/potting interface on the first end and having a shell/potting interface on the second end;
a first seal comprising an O-ring in a groove between the shell and the housing adjacent the first end and located distally within a length of the shell/potting interface on the first end, and a second seal comprising an O-ring in a groove between the shell and the housing adjacent the second end and located distally within a length of shell/potting interface on the second end; and
at least one support shim between the housing and the shell, and the at least one support shim positioned between the first seal and the second seal.

2. The degassing module of claim 1 wherein the housing encloses a plurality of the cartridges.

3. The degassing module of claim 1 wherein the housing is a standard reverse osmosis pressure vessel.

4. The degassing module of claim 1 wherein the at least one support shim comprises a first support shim positioned between the first seal and the second seal adjacent the first seal, and a second support shim positioned between the first seal and the second seal adjacent the second seal.

5. The degassing module of claim 4 wherein the first and second support shims comprise rings encircling the shell.

6. The degassing module of claim 4 wherein the at least one support shim comprises a third support shim located between the first support shim and the second support shim.

7. The degassing module of claim 6 wherein the third support shim comprises a third central shim.

8. The degassing module of claim 6 wherein the first support shim, the second support shim, and the third support shim comprise rings encircling the shell.

9. The degassing module of claim 1 wherein the at least one support shim comprises a plurality of shims spaced about the shell.

10. The degassing module of claim 9 wherein the plurality of shims comprise spaced pads located adjacent the first end and spaced pads located adjacent the second end and wherein the spaced pads encircle the shell.

11. The degassing module of claim 9 wherein the plurality of shims comprise spaced pads extending between the first end and the second end and wherein the spaced pads encircle the shell.

12. The degassing module of claim 1 wherein the at least one support shim comprises a spiral wrap.

13. The degassing module of claim 4 wherein the first support shim is located 0.1 to 1.5 inches from the first end and the second support shim is located 0.1 to 1.5 inches from the second end, the first support shim and the second support shim each being 1 to 4 inches wide, and the first support shim and the second support shim are 0.005 to 0.1 inches thick.

14. The degassing module of claim 1 wherein the at least one support shim fills at least a portion of a gap between an exterior of the shell and an interior of the housing.

15. The degassing module of claim 1 wherein the at least one support shim comprises a length of tape wound onto the exterior of the shell in a plurality of turns.

16. The degassing module of claim 15 wherein the tape comprises polyethylene tape.

17. The degassing module of claim 15 wherein the tape comprises a thickness from 0.005 to 0.015 inches and a width from 1.5 to 3.0 inches.

18. The degassing module of claim 1 wherein the at least one support shim is attached to an exterior of the shell.

19. The degassing module of claim 1 wherein the at least one support shim is attached to an interior of the housing.

20. A cartridge for a degassing module comprising:
a cartridge having a shell with a first end, a second end, an interior surface, and an exterior surface;
the shell enclosing a plurality of hollow fibers;
a center tube extending through the plurality of hollow fibers;
the plurality of hollow fibers having potting securing the ends of the plurality of hollow fibers between the center tube and the interior surface on both the first and the second ends;
a first exterior O-ring groove on the exterior surface, the first exterior O-ring groove spaced inwardly away from the first end and located distally within a length of the potting on the first end and an O-ring located in the first exterior O-ring groove; and
a first support shim on the exterior surface, the first support shim spaced inwardly away from the first exterior O-ring groove.

21. The cartridge of claim 20 comprising:
a second exterior O-ring groove on the exterior surface, the second exterior O-ring groove spaced inwardly away from the second end the potting on the second end and an O-ring located in the first exterior O-ring groove; and
a second support shim on the exterior surface, the second support shim spaced inwardly away from the second exterior O-ring groove.

22. The cartridge of claim 21 wherein the first support shim is located 0.1 to 1.5 inches from the first end and the second support shim is located 0.1 to 1.5 inches from the second end, the first support shim and the second support shim each being 1 to 4 inches wide, and the first support shim and the second support shim are 0.005 to 0.1 inches thick.

23. The cartridge of claim 20 wherein the first support shim comprises a length of a strip of material wound in a plurality of turns about the exterior of the shell.

24. The cartridge claim 23 wherein the strip of material comprises a thickness from 0.005 to 0.015 inches and a width from 1.5 to 3.0 inches.

25. The cartridge of claim 20 comprising a housing having a plurality of ports and the housing enclosing the cartridge thereby forming the degassing module.

26. A cartridge for a degassing module comprising:
a cartridge having a shell with a first end, a second end, an interior surface, and an exterior surface;
the shell enclosing a plurality of hollow fibers;
