<p>A method and apparatus for removing fouling materials from the surface of a plurality of porous membranes (5) arranged in a membrane module (4) 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 (5) to dislodge fouling materials therefrom. The membranes (5) 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 (5) to further assist removal of fouling materials.</p> |
