摘要：This research was conducted to evaluate the effects of thermal
and ultrasound disintegration on the disintegration degree (DD) of water
treatment sludge from a municipal water treatment plant. A disintegration
process was used to (i) improve subsequent coagulation efficiencies and
dewatering processes (ii) reduce sludge production, and (iii) obtain both
economic and enviromental benefits. The results show that using the
disintegration process has an influence on DD values. It is also worth
emphasising that the main parameter determining the efficiency of
ultrasonic and thermal disintegration was the time of the applied process.
Other parameters such as ultrasound intensity and temperature had
a reduced impact on DD values.
