Submerged diffuser lifting arrangement
TLDR
In this article, a plurality of submerged air diffuser arrangements are disposed adjacent to the bottom of in a body of wastewater to be aerated and connected an air supply pipe extending along the surface of the wastewater.Abstract:
In the submerged diffuser arrangement described in the specification, a plurality of submerged air diffuser arrangements are disposed adjacent to the bottom of in a body of wastewater to be aerated and connected an air supply pipe extending along the surface of the wastewater. Air is supplied from the air supply pipe through downcomers leading to the diffuser arrangements. The diffusers may be suspended from the air pipe above the bottom or they may rest on the bottom. In order to raise the diffuser arrangements to the surface of the wastewater for servicing, inflatable buoyant members are affixed to each diffuser arrangement or to the lower ends of the associated downcomers. The inflatable buoyant members are connected through tubing to valves from which air may be supplied under pressure, either from the air supply pipe or form a portable air compressor or a compressed air container or through an air pressure line leading from a remote air supply located on the shore of the basin.read more
