A filtering assembly includes a screen housing having two sidewalls and two end walls, defining a perimeter with a length and a width. The screen housing also includes a top face and a bottom face. A plurality of screen segments are positioned on the top face of the screen housing, such that the plurality of screen segments on the top face provide a screening surface area less than a total surface area of the top face, and a plurality of screen segments are positioned on the bottom face of the screen housing, such that the plurality of screen segments on the bottom face provide a screening surface area less than a total surface area of the bottom face. A total screening surface area of the filtering assembly is greater than the total surface area of the top face.
