Due to the different ultrasonic conditions and anaerobic digestion conditions, the effect of ultrasonic pretreatment on anaerobic digestion can be different. In this study, 20 kHz of low frequency ultrasound was used to treat waste activated sludge at different time range from 0 to 100 min at ultrasound densities of 0.5 W/mL. The purpose of this study was to investigate the diversity of archaea in anaerobic sludge.
