AB  - The effect of potassium ferrate/ultrasonic (K2FeO4/US) treatment on the 
      physicochemical features of textile dyeing sludge was studied. The soluble 
      chemical oxygen demand (SCOD), deoxyribonucleic acid (DNA), sludge volume index 
      (SVI), sludge viscosity, capillary suction time (CST) and particle size were 
      measured to understand the observed changes in the sludge physicochemical 
      features. The results showed that the combined K2FeO4/US treatment presented 
      great advantages for disrupting the sludge floc structure over K2FeO4 or 
      ultrasonic treatments alone. The optimal parameters of sludge disintegration were 
      found to be a K2FeO4 treatment time of 60 min, a K2FeO4 dosage of 0.5936 g/g SS, 
      an ultrasonic time of 15 min and an ultrasonic intensity of 0.72 W/mL. The 
      initial median diameter of the sludge particles was 15.24 mum, and this value 
      decreased by 35.89%. The CST was initially 59.6 s and increased by 231%, whereas 
      the SVI was 97.78 mL/g and decreased by 25.89%. Scanning electron microscope 
      (SEM) images indicated that the sludge surface was irregular and loose with a 
      large amount of channels or voids during K2FeO4/US treatment. K2FeO4/US treatment 
      synergistically enhanced the sludge solubilization and reached 668.67 mg/L SCOD, 
      which is 31.81% greater than the additive value obtained with K2FeO4 treatment 
      alone (215.95 mg/L) or with ultrasonic treatment alone (240 mg/L).
