<p>TUBULAR FILTER ELEMENT A filter element including a perforated tubular member for supporting a filter medium, a tubular distributor core concentrically located within the support member and having a plurality of aperatures in the core wall, and a plurality of dividers positioned around the tubular distributor core to prevent the unimpeded flow of liquid through the annular space between the support member and the distributor core and to provide a plurality of annular chambers between the core and the support member. The dividers are located so that the ratio of the flow of liquid through the aperatures into an annular chamber to the area of the support member served by the annular chamber is the same for all chambers. In an alternative embodiment the diameter of the apertures is varied along the length of the filter element to assist in distributing the flow of liquid.</p> |
