At one end of the casing (40) there is a header (41) which has a feed passageway (55) therethrough and in communication with the interior of the casing (40) and the exterior of the fibres. The header (41) also has a filtrate passageway (64) therethrough and in communication with the open ends of the fibres. At the other end of the casing there is a second header (42) which has a treated feed passageway (72) therethrough and in communication with the interior of the casing (40) and the exterior of the fibres. The header (42) also has a filtrate passageway (74) therethrough and in communication with the open ends of the fibres. The feed, treated feed and filtrate passageways (55, 72, 64 & 74) area formed in the off set portions (56, 73, 65 & 75) of the headers (41, 42) that have planar parallel end faces whereby a plurality of filter units may be joined together without a manifold to form a bank of filters.
