Bottom Discharge Clog-Free Discharge Diffuser

Bottom Discharge Clog-Free Discharge Diffuser
Diffusers measure 5" Dia x 4.5"H with ½" NPT (male) threads. Units can handle 1 to 13 SCFM, with the best efficiency between 6 and 12 SCFM.

These clog free, bottom discharge diffusers use a trapped bubble of air to keep wastewater out of the air pipes and do not clog!

Air pumped through the piping of the plant's diffusion system must be broken into small bubbles for better oxygen transfer efficiency. Streams of air passing through these diffusers are first broken up when passing through the sectioned orifice. Next, the rubber diaphragm, blown aside by the force of air rushing in, continues to break up the air stream. Finally, notches at the base of the diffuser break the air into still smaller bubbles giving greater surface area for more contact with the wastewater. This greater bubble surface area transfers much more oxygen to the wastewater than large bubbles do. The end result is high oxygen transfer efficiency and a mixing action giving smooth, even, fast aeration process.
