<p num="1"><br/><br/><br/>A method of operating a membrane filtration module (5), the module (5) <br/>including one or more membranes (7) extending longitudinally between <br/>vertically spaced upper and lower headers (8, 9) into which the ends of the <br/>membranes (7) are potted. The membranes (7) have a permeable wall which is <br/>subjected to a filtration operation wherein feed containing contaminant matter <br/>is applied to one side of the membrane wall and filtrate is withdrawn from the <br/>other side of the membrane wall. At least one of the upper and/or lower <br/>headers (8, 9) has one or more openings (10) therein and the method including <br/>flowing the feed, at least in part, through the one or more openings (10) for <br/>application to the membrane wall. Apparatus for performing the method is also <br/>disclosed.<br/>
