Dissolved air flotation (DAF) waste, a byproduct with high lipid content separated from dairy wastewater, is disposed of by land spreading and causing environmental pollution. To develop a sustainable treatment for DAF waste, this study investigated the effects of food to inoculum (F/I) ratio and ultrasound pre-treatment on the anaerobic digestion...

Municipal wastewater constitutes the largest fraction of wastewater, and yet treatment processes are largely removal-based. High-rate anaerobic digestion (AD) has revolutionised the sustainability of industrial wastewater treatment and could additionally provide an alternative for municipal wastewater. While AD of dilute municipal wastewater is com...

Fermentation 2023, 9, 903 2 of 18 on hydraulic retention time (HRT) [9,10], organic loading [11,12], bioreactor configuration [13,14], etc. Compared with a moderate temperature, the psychrophilic temperature (<20 • C) [15,16] is relatively less suitable for microbial growth and metabolism in anaerobic digestion. However, low-temperature anaerobic digestion (LT-AD) requires considerably less energy input than mesophilic AD and has become a research focus. ...
