Abstract
The diffuser assembly of the present invention includes first and second diffuser bodies in fluid communication with an air distribution pipe. The diffuser assembly further includes a saddle that supports the first diffuser body and the second diffuser body. The saddle is connected to the distribution pipe by a hollow core rivet. Gas is forced from the distribution pipe through the hollow core rivet where the gas passes into the first and second diffuser bodies. The gas exits the first diffuser body through a first diffusion media and exits the second diffuser body through a second diffusion media. The first and second diffusion media form the gas into fine bubbles that serve to facilitate aeration of a fluid.
Claims26
A diffuser assembly for diffusing a gas received from a distribution pipe into a fluid in order to aerate the fluid, said diffuser assembly comprising:
- a first diffuser body in fluid communication with the distribution pipe;
- a second diffuser body in fluid communication with the distribution pipe;
- a first diffusion media supported by said first diffuser body such that the gas flows from the distribution pipe into said first diffuser body and through said first diffusion media into the fluid;
- a second diffusion media supported by said second diffuser body such that the gas flows from the distribution pipe into said second diffuser body and through said second diffusion media into the fluid;
- a saddle supporting said first diffuser body and said second diffuser body;
- and
- a first hollow core rivet connecting said saddle to the distribution pipe such that the gas flows from the distribution pipe through said first hollow core rivet into said first diffuser body and said second diffuser body.
A system for aerating wastewater comprising:
- an air distribution pipe for supplying air,
- a plurality of diffuser assemblies adapted to diffuse air received from said distribution pipe into the wastewater, each of said diffuser assemblies is mounted along said air distribution pipe and includes,
- a first diffuser body in fluid communication with said distribution pipe;
- a second diffuser body in fluid communication with said distribution pipe;
- a first diffusion media supported by said first diffuser body;
- a second diffusion media supported by said second diffuser body;
- a saddle supporting said first diffuser body and said second diffuser body;
- and
- a first hollow core rivet connecting said saddle to said distribution pipe such that air flows from said distribution pipe through said first hollow core rivet into said first diffuser body and said second diffuser body.
A system for aerating wastewater comprising:
- an air distribution pipe for supplying air,
- a plurality of diffuser assemblies adapted to diffuse air received from said distribution pipe into the wastewater, each of said diffuser assemblies is mounted along said air distribution pipe and includes,
- a diffuser body in fluid communication with said distribution pipe;
- a diffusion media supported by said diffuser body;
- a saddle supporting said diffuser body;
- and
- a hollow core rivet connecting said saddle to said distribution pipe such that air flows from said distribution pipe through said hollow core rivet into said diffuser body.
A system for aerating wastewater comprising:
- an air distribution pipe for supplying air, a plurality of diffuser assemblies adapted to diffuse air received from said distribution pipe into the wastewater, each said diffuser assembly is mounted along said air distribution pipe and includes,
- a first diffuser body in fluid communication with said distribution pipe;
- a second diffuser body in fluid communication with said distribution pipe;
- a first diffusion media supported by said first diffuser body;
- a second diffusion media supported by said second diffuser body;
- a saddle supporting said first diffuser body and said second diffuser body;
- a first hollow core rivet having internal threads, said first hollow core rivet including a head compressed against an outside surface of said distribution pipe when said first hollow core rivet is staked against an inside surface of said distribution pipe, and
- a hollow core bolt connecting said saddle to said distribution pipe such that air flows from said distribution pipe through said first hollow core bolt into said first diffuser body and said second diffuser body.
A diffuser assembly for diffusing a gas received from a distribution pipe into a fluid in order to aerate the fluid, said diffuser assembly comprising:
- a diffuser body in fluid communication with the distribution pipe;
- a diffusion media supported by said diffuser body such that the gas flows from the distribution pipe into said diffuser body and through said diffusion media into the fluid;
- a hollow core rivet connecting said diffuser body to the distribution pipe such that the gas flows from the distribution pipe through said hollow core rivet into said diffuser body.
