| Summary: | Authors and Affiliation: Omprakash Sarkar*, Leonidas Matsakas, Ulrika Rova, Paul Christakopoulos, Biochemical Process Engineering, Division of Chemical Engineering, Department of Civil, Environmental, and Natural Resources Engineering, Luleå University of Technology, 971‑87 Luleå, Sweden, Email: omprakash.sarkar@ltu.se Abstract The present study explored the influence of ultrasound on acidogenic fermentation of wastewater for the production of biohydrogen and volatile fatty acids. Eight sono-bioreactors underwent ultrasound (20 kHz: 2 and 4W), with an ultrasound duration ranging from 15 minutes to 30 days, and the formation of acidogenic metabolites. Long-term continuous ultrasonication enhanced biohydrogen and volatile fatty acid production. Specifically, ultrasonication at 4W for 30 days increased biohydrogen production by 3.05-fold compared to the control, corresponding to the hydrogen conversion efficiency of 58.4%; enhanced volatile fatty acid production by 2.49-fold; and increased acidification to ... |
