In an effort to acquire better knowledge, and to demonstrate performance characteristics of some of the new fine bubble diffusers, SSI has conducted extensive testing programs to evaluate and compare oxygen transfer performance of the AFD270 and AFD350 EPDM membrane diffusers. Other tests include:
- Data on significant use of the steady state mixed liquor column test to obtain suitable data for predicting both the oxygen uptake rate and alpha factor for various locations within an aeration basin.
- Selected projects related to Oxygen Transfer Systems conducted by independent engineering firm Redmon Engineering.
- Report on Diffuser Data Oxygen Transfer Tests Conducted at Barcelona from Sep 21st to Oct 18th 2005 (PDF).
- Report on Diffuser Data Oxygen Transfer Tests Conducted at Barcelona from Sep 23rd to Oct 9th 2003 (PDF).
- Steady State Column Tests comparing Alpha in zones of a BNR and New and Aged diffusers (.xls).
- Efficiency curves for AFD270 and AFD350 Fine Bubble Diffusers (PDF).
