ABSTRACT:
A self-supporting modular underdrain member for use in a liquid filtration system comprises a main body or housing including a pair of longitudinally extending inclined walls which may have a pair of generally triangular transverse walls connecting the inclined walls to one another, the inclined walls each being provided with a pair of longitudinally extending recesses and a plurality of orifices communicating with each of the recesses. A pair of flanges are connected to the inclined walls for attaching the underdrain body to a floor surface so that the inclined walls, any transverse walls and the floor surface define a cross-sectionally triangular underdrain chamber. Two pairs of elongate cover plates are attached to the inclined walls over the recesses to form in each of the inclined walls a pair of longitudinally extending plenums for the equalization of backwash air and water flow. Each of the cover plates being provided with a plurality of spaced slots.
