| Zusammenfassung: | A method and filtration module for providing gas bubbles within an array of vertically disposed porous hollow membranes to clean the outer surfaces of said membranes when the array is immersed in a liquid by feeding the gas bubbles into the array transversely of the vertical axis of the array. In one preferred form, the gas bubbles are retained within the array using a sleeve surrounding the array at least along part of its length. |
