Abstract

To test the apparent viscosity of the sludge after hydrothermal pretreated for recovering energy with sludge spray incineration and sludge transportation of sewage sludge. hydrothermal pretreatments and in turn viscosity measurement/particle size distribution measurement/solid volume fraction measurement of the slurry obtained from the pretreated sludge were performed at laboratory-scale. The results particle size distribution and solid volume fraction of the sewage sludge was decreased with increasing pretreatment temperature 473 K-513 K. The decreasing of particle size distribution and solid volume fraction gave a better performance on the fluidity of the pretreated sludge.
