Abstract: An SBX assembly comprising an ultrafine screen; a three-dimensional screen frame supportive of the screen and sealed along the screen edges to prevent liquids and solids from bypassing the screen; and an air plenum attached to the frame that provides air scouring at the lowest elevation of the screen. The air plenum is attached to the lower region of the SBX. The plenum is supplied from a source of compressed air and is provided with a plurality of exit holes. Air exiting the plenum flows along the upstream surface of the SBX screening below the level of liquid in the primary settling tank, thereby scouring accumulated residues from the screening surface. Upon reaching the liquid surface, the bubbles migrate horizontally away from the SBX assembly and toward one or more nearby scum troughs in the primary settling tank.
