1. A membrane module comprising a plurality of porous hollow fibre membranes, said membranes being arranged in close proximity to one another and mounted to prevent excessive movement therebetween but unconfined in a solid modular shell, and a gas distribution means having holes or openings connected through a header used to mount the membranes to air tubes adapted to be connected to a source of pressurized gas for providing, from within the module, by means other than gas passing through the pores of said membranes, gas bubbles such that, in use, said bubbles move past the surfaces of said membranes to dislodge fouling materials therefrom and cause the membranes to sway.
