- •
Continuous ultrasonic sludge treatment device with multiple transducers is designed.
- •
The characteristics of the ultrasonic wave propagated in the activated sludge are investigated by simulation.
- •
Activated sludge is ultrasonically treated with different exposure times and frequencies, and the capillary suction time, particle size, and moisture content change accordingly.
- •
Ultrasonic treatment can improve gas production.
