Impact of worm predation on pseudo-steady-state of the circulating fluidized bed biofilm reactor

- This study demonstrated one bioparticle system with worm predation for COD and N removal.
- The steady-state in the CFBBR for integrated COD, N removal and worm predation was studied.
- A self-balancing worm bioparticle process and BEP circulation was established in the CFBBR.
