Abstract
A membrane filtration assembly (10) including having a filtrate carrier (9) for minimizing backwash. The membrane filtration assembly includes a membrane module (5) having one or more permeable hollow membranes (6) supported therein by an upper header (7) and a lower header (8). The filtrate carrier (9) extends between the upper (7) and lower (8) headers to allow filtrate to be collected from either or both ends of membranes (6). A filtrate collection chamber (18) is associated with the upper (7) and lower headers (9) and in fluid communication with lumens of the membranes (6) for collecting filtrate withdrawn through said membrane lumens. A filtration chamber (11) is provided for receiving feed liquid to be applied to the surface of membranes (6) within the module (5). The filtration chamber (11) includes an open end for receiving the feed liquid. The open end is located beyond the height of the module (5) to enable gravity feed.
