Performance evaluation of a novel anaerobic digestion operation process for treating high-solids content chicken manure: Effect of reduction of the hydraulic retention time at a constant organic loading rate

[Display omitted] •A novel feeding strategy, keeping constant OLR but reducing HRTCM was adopted.•The effect of reducing HRTCM on CH4 fermentation of chicken manure was studied.•High content of ammonia was the main inhibition factor at HRTCM of 52days.•Reduce in HRTCM relaxed the inhibition of high...
