The application of low-frequency ultrasound irradiation to domestic wastewater has demonstrated its potential to reduce organic matter and microbial counts in experimental samples, according to a study by Hoang Duc An, Huynh Thi Minh Thanh, and Vo Thi Hong Phuong of the Faculty of Natural Sciences, Quy Nhon University. The findings also indicate that treatment performance depends on operating conditions and influent wastewater quality, suggesting that ultrasound could serve as a supplementary step in wastewater treatment processes.
