Abstract
A gas baffle for a waste water treatment plant filter housing that includes a first and second deflecting plate. The gas baffle has at least one flow-through opening defined by the first and second deflecting plates. The combination of the first and second deflecting plates deflects rising gas bubbles and any solid particulates so that the bubbles and particulates do not enter the filter housing. The gas baffle may include exterior apertures to dissipate the rising gas bubbles that travel on the bottom surface of each deflecting plate. The gas baffle may be integrally formed with the filter housing or created separately and subsequently connected.
