During Session No. 207 at WEFTEC 2017, Aeration: Knowledge Development Forum, Diego Rosso will talk about using a dynamic model to identify energy conservation opportunities in aeration systems.

Rosso, an associate professor in the University of California, Irvine’s (UCI’s) Civil and Environmental Engineering Department and director of UCI’s Water-Energy Nexus Center, joined other researchers to test an activated sludge model’s ability to dynamically control energy used by aeration systems. The model describes the hydraulic loading dependence of the alpha factor — the ratio of process-water oxygen transfer relative to clean-water oxygen transfer — in activated sludge fine-pore aeration.

Rosso has been investigating the water-energy-carbon nexus as well as water reclamation and reuse processes since 2000. A chemical engineering laureate from the University of Padua in Italy, he earned a doctorate in environmental engineering from University of California, Los Angeles (UCLA). Rosso is chair of the WEFTEC Municipal Symposium and Ambassador of the Water Environment Federation (Alexandria, Va.).

The forum also presents other discussions on the newest developments in research on aeration systems. Organizers of the event invite attendees to also participate in the mobile session on aeration diffusers and blowers.

  • What are the key takeaways from your presentation?
    • Alpha factors are dynamic.
    • It is not a matter of a better aeration diffuser but of better fit for the application and site.
    • Independent testing of the aeration system reduced substantially the uncertainty and pitfalls in design.
  • What makes your project/presentation most interesting?

The involvement of utilities and consulting firms with applied academics.

  • What or who inspired you to get into this sector?

My former adviser, Mike Stenstrom from UCLA, who is both an outstanding professor and an exceptional engineer.

  • How do you pass on that inspiration to others?

I pass on inspiration by paying forward what I learned from my adviser:

• bring your work to the field and bring the field back to your lab, and
• have your student with you throughout the process.
