文摘
- •
Full-scale modification of anaerobic digestion parameters to investigate foaming causes.
- •
The suspected contributors to anaerobic digester foaming were present in all 3 cases.
- •
No foaming occurred because primary foaming cause was absent.
- •
Reduced mixing to abate foaming did not affect homogeneity in digesters.
