ABSTRACT:
An aeration apparatus for a wastewater treatment plant having an air line connected to an air source, a drop line connected in fluid communication with the air line, a check valve positioned in the drop line between an orifice at the bottom of the drop line and the air line, and a diffuser member extending around the orifice on the drop line. The check valve serves to prevent liquid from passing therethrough. The drop line includes a tube which extends downwardly from the air line, an upper adapter fastened to an end of the tube opposite the air line, and a lower adapter engaging the upper adapter in fluid communication with said tube. The upper adapter is a male threaded member and the lower adapter is a female threaded member. The check valve is affixed within the lower adapter adjacent to the female threads. The check valve includes a disk having a plurality of holes extending therethrough and a resilient flap valve extending over the holes and juxtaposed against the disk.
