|a The role of total solids (TS) content on sludge mesophilic anaerobic digestion (AD) was investigated in batch reactors. A range of TS below 10% was evaluated with two replicates. The volumetric biogas production rate (VBPR) increased with increasing initial TS. On day 5, VBPR increased from 133.2±11.2mLL-1d-1 at TS 2% to 1111.7±58.1mLL-1d-1 at TS 10%. The ultimate biogas yield (P) firstly increased and then decreased with the increasing TS. The greatest P was 246.8mLg-1-VSadded at TS 8%. The corresponding free ammonia nitrogen (FAN) and total ammonia nitrogen (TAN) were 84.0±16.1 and 1163.0±108.6mgL-1, respectively. Normalized capillary suction time (NCST) and solid content of thickened sludge obtained by centrifuging sludge increased with increasing TS. On day 49, NCST were 1.2±0.2 (TS=2%) and 13.2±1.1 (TS=10%)sg-1-TS. Meanwhile, solid content of thickened sludge was 7.5±0.5 (TS=2%) and 15.4±0.0% (TS=10%). In summary, high VBPR and dewatering effects were obtained after TS content optimization
