| 1995 | Invention patented by Charles E. Tharp on June 5th, 1995. Abstract: An aeration/mixing system for applying air or another gas to wastewater or another liquid. A main air supply pipe receives air from a blower and directs the air to a plurality of aeration modules each including a submerged conduit and a plurality of diffusers on the conduit. Flexible hoses connect the main pipe with the conduit of each module. In one form of the invention, a flexible line connected with each module has a sliding connection with a ballast block and may be pulled tautly and secured at the surface to hold the module down in the basin. Retrieval of the module for maintenance requires only that the line be released so that the buoyancy of the module floats it upwardly. A modified embodiment includes an inflatable bladder on each module which can be inflated to cause the module to float upwardly for retrieval. |
