Research Questions

  • What are the limits to total nitrogen removal from mainstream anaerobic processes?
  • Which microbial populations contribute to nitrogen removal from these processes?
  • How do we apply sensor-mediated controls in a granular sludge reactor?

Research Approach

We integrated one-dimensional biofilm modeling and lab-scale reactors to understand these technologies.
