ABSTRACT:
An air diffusion apparatus for aeration of rotating biological contactors or other media in a liquid filled tank includes an air supply manifold, a drop pipe connected to the air supply manifold, and a diffuser header assembly connected to the drop pipe. The diffuser header assembly has shoes allowing it to roll or slide against the tank walls and bottom during installation and removal. The diffuser header assembly is negatively buoyant during installation and operation of the apparatus, so that attachment of the diffuser header to the bottom or sides of the tank is not required. This results in easy installation and removal of the apparatus without requiring prior removal of the contactor or other obstructions from the tank.
