摘要: Abstract An examination of the rheological properties activated sludges from three sewage treatment works and a digested sludge dual mesophilic-thermophilic anaerobic digester (TAD-MAD) showed that all exhibited yield stresses magnitude which varied with suspended solids’ concentration type they had received. In particular, TAD-MAD stress was an order lower than at comparable concentrations. Treatment ultrasound reduced values this effect irreversible. The surface charge carried by particles bound water were both found to be related stress. content samples filtration characteristics, as measured capillary suction time method. However, have poor characteristics. Microscopic examinations contained predominance small (
