- •
Ammonium dynamics and control in anaerobic digestion of chicken manure was investigated.
- •
Organic and inorganic compounds significantly accumulated after direct slurry recirculation.
- •
Accumulated VFAs and ammonium resulted in decrease of biogas production of 43%.
- •
Integration of air stripping before recirculation shows to be effective for ammonium mitigation.
