文摘
- •
Ultrasound was applied on three typical types of specific BNR activated sludge.
- •
Mean particle sizes after sufficient sonication were similar for different sludge.
- •
SCOD increased rapidly at the earlier time of sonic treatment.
- •
Ammonia release during the ultrasound treatment would not inhibit CH4 production.
- •
Ultrasonic density of 1.04 W mL−1 was economic and effective.
