Fine bubble aeration and diffuser types
Fine bubble aeration and diffuser types
(OP)
Hellow Everyone
I am designing a SBR for treating municpal wastewater. I got a bit confused in determining the right type of diffusers. Can anyone help?
Also, I found that disk diffusers have higher pressure loss in the long run, and I need to relate this pressure loss to the blower capacity.
Thanks in advance for your input and time.

RE: Fine bubble aeration and diffuser types
You are wasting your time talking to the sales people that supply these items because everyone of them will tell you that his product is better than the competition.
Refer to Metcalf & Eddy for how to design the aeration system.
RE: Fine bubble aeration and diffuser types
Can anyone calrify what do they mean by SOTE, is it amount of oxygen uptake/ amount of air supplied?
Thanks
RE: Fine bubble aeration and diffuser types
The reason SOTE is used is so that all suppliers of aeration systems can state the performance of their aeration devices at the same operating condition.
Unfortunately the ratio AOR/SOR is not the same for all aeration devices.
