Integrated approach to sustain biogas production in anaerobic digestion of chicken manure under recycled utilization of liquid digestate: Dynamics of ammonium accumulation and mitigation control.
TL;DR: Air stripping was integrated for ammonium mitigation of recycled liquid digested slurry and was shown to effectively reduce the ammonium to 3000mg/L, indicating the potential of the integration of air stripping in an anaerobic digestion process with liquid digesting slurry recirculation.

Exploring stability indicators for efficient monitoring of anaerobic digestion of pig manure under perturbations.
TL;DR: The response of two experimental, continuously stirred tank reactors under mesophilic condition was investigated to analyze the perturbation of organic and hydraulic overloading, and low-temperature shock, and the pH was stably maintained in the range of 7.2-7.7, regardless of the presence of most simulated perturbations.

Development and validation of a simplified titration method for monitoring volatile fatty acids in anaerobic digestion.
TL;DR: A simplified titration method was developed and validated using a semi-continuous experiment of chicken manure anaerobic digestion with various organic loading rates and the good fitting of the results obtained in comparison with GC results strongly supported the potential application of this method to VFA monitoring.
