ABSTRACT:
A diatomaceous earth caking filter element includes a first elongated tubular manifold having a slot therein and a suction coupling formed thereon for drawing a liquid from said first manifold. A second elongated tubular manifold has a slot therein and a plurality of hollow pipes connected between the first and second manifolds with one end of each pipe extending into the first manifold through the slot therein and the other end of each pipe extending into the second manifold through the slot therein. Each pipe is held by the slot edges of each manifold extending into an annular groove on each end of each pipe. A filter cake screen covers both sides of the plurality of hollow pipes for catching a filtering medium, such as diatomaceous earth, thereon for filtering liquid passing therethrough, so the liquid can be drawn through the filter medium and filter screen into the first and second manifolds and out the suction coupling. The liquid is drawn into both manifolds at both ends of the filter element to provide a more uniform flow of liquid through the filter cake and screen and to provide a more even distribution of the filter cake.
