Zusammenfassung:	An underdrain assembly for filtering particulates from a fluid having an upper structure connected to a bottom plate. The upper structure has first and second filtration members, the second filtration member positioned between the first filtration member and the bottom plate. The second filtration member has a shape that restricts fluid flow within the underdrain. The second filtration member may have a cross-sectional shape that is different from a cross-sectional shape of the first filtration member. The second filtration member may have a cross-sectional shape selected from the list consisting of concave, convex, z-shaped, s-shaped w-shaped and v-shaped.
