A method and apparatus for cleaning a membrane module, the membrane module having a plurality of porous membranes, the membranes being arranged in close proximity to one another and mounted to prevent excessive movement therebetween and means for providing, from within the module, by means other than gas passing through the pores of the membranes, gas bubbles entrained in a liquid flow such that, in use, the liquid and bubbles entrained therein move past the surfaces of the membranes to dislodge fouling materials therefrom, the gas bubbles being entrained in the liquid by flowing the liquid past a source of gas to draw the gas into the liquid flow. The gas bubbles are preferably entrained into the liquid using a venturi type device. The membranes are preferably partitioned into discrete groups to assist cleaning while maintaining high packing density.

The assembly as set forth in claim 14 wherein the at least one portion of the side wall having the first thickness is flexible. 17. The assembly as set forth in claim 14 wherein the at least one portion of the side wall having the first thickness is substantially flat. 18. The assembly as set forth in claim 17 wherein the opening extends along an axis, and wherein the at least one portion of the side wall having the first thickness includes an axially-extending external groove. 19. A method of assembling a joint assembly, the method comprising the acts of: providing a first yoke including a ball portion and a second yoke defining a socket, the socket having a socket inner surface; positioning a sleeve in the socket, the sleeve defining an opening for receiving the ball portion, the sleeve having a continuous side wall, a portion of the side wall being flexible, the opening being non-circular such that the opening, in a relaxed state, has at least first and second diameters that are distinct from one another; and positioning the ball portion in the opening in the sleeve. kept under a clean environment and having a box lid opening/closing mechanism for opening/closing the lid member of the clean box; wherein: said clean box is disposed so that said lid member and the box lid opening/closing mechanism on a side of the load port are aligned to confront with each other; and said load port has a device for vacuum exhausting/releasing said substantially vacuum-tight suction space through said intake/exhaust port of the clean box. 7. A clean transfer system according to claim 6, wherein said clean box has a valve device for allowing gas to be introduced and discharged for replacement of gas in said clean box. 8. A clean transfer system according to claim 7, wherein said valve device comprises a gas input valve for introducing a non-oxidizing gas into the interior of the clean box and a gas output valve for discharging the gas within the clean box to the outside of the clean box. 9. A clean transfer system according to claim 8, wherein said load port has a gas feed device in cooperation with the gas input valve and a gas discharge device in cooperation with the gas output valve. 10. A clean transfer system according to claim 7, wherein said load port has means for replacing gas in the interior of the clean box in cooperation with said valve device. 11. A clean transfer system according to claim 10, wherein said intake/exhaust port and said valve device are provided on the same single side surface of the clean box body, and the device for vacuum exhausting/releasing and the means for replacement of the gas in the interior of the clean box are constituted as a single unit so that the clean box may be accessed by one operation. 12. A clean box comprising: a box body having an opening in one surface thereof; a lid member for closing said opening; a substantially vacuum-tight annular groove formed so as to surround said opening on at least one of said box body and said lid member, said substantially vacuum-tight annular groove being configured to form a substantially vacuum-tight suction space sealed by said lid member and said box body when said lid member is mounted on said box body; and an intake/exhaust port for allowing vacuum exhaust/release of said substantially vacuum-tight annular groove, said intake/exhaust port being formed on said lid member. 13. A clean box according to claim 12, further comprising a valve device for allowing gas to be introduced or discharged for replacement of gas in the interior of the clean box is provided on the lid member. 14. A clean box according to claim 12, further comprising a mechanical latch for latching the lid member to the box body. 15. A clean box according to claim 14, wherein said mechanical latch has a mechanism for opening/closing said latch from outside on the side of said lid member. 16. A clean transfer system comprising: a clean box including a box body having an opening in one surface thereof, a lid member for closing said opening; an annular groove formed so as to surround said opening on at least one of said box body and said lid member to define a suction space sealed between said lid member and said box body when said lid member is mounted on said box body, and an intake/exhaust port for allowing vacuum exhaust/release of said annular groove said intake/exhaust port formed on said lid member; and a load port of a clean device whose interior is kept under a clean environment and having a box lid opening/closing mechanism for opening/closing the lid member of the clean box; wherein: said clean box is disposed so that said lid member and the box lid opening/closing mechanism on a side of the load port are aligned to confront with each other; and said box lid opening/closing mechanism of the load port releases the vacuum of the suction space through said intake/exhaust port formed on said lid member of the clean box, opens said lid member, and picks up an article to be transferred in the interior of the clean box. 17.
