In this research autothermal thermophilic aerobic digestion (ATAD) of a typical waste activated sludge (WAS) was investigated in a continuous stirred digester, precisely. Volatile solids (VS) reduction, energy audit, pathogen inactivation and sludge dewaterability during aerobic digestion were studied.

Bacterial community analysis of swine manure treated with autothermal thermophilic aerobic digestion
Applied Microbiology and Biotechnology, 2011Due to the environmental problems associated with disposal of livestock sludge, many stabilization studies emphasizing on the sludge volume reduction were performed. However, little is known about the microbial risk present in sludge and its stabilized products.

The one-stage autothermal thermophilic aerobic digestion for sewage sludge treatment
Chemical Engineering Journal, 2011Abstract One-stage autothermal thermophilic aerobic digestion (ATAD) is promising for sewage sludge stabilization in small- and medium-sized wastewater treatment plants (WWTPs). A one-stage ATAD large-scale digester was designed with effective volume 10 m3, and batch-mode operation was conducted on sewage sludge to evaluate the effectiveness of the ...

An evaluation of autothermal thermophilic aerobic digestion (ATAD) of municipal sludge in Ireland
Journal of Environmental Engineering and Science, 2007Autothermal thermophilic aerobic digestion (ATAD) is an exothermic process where sludge is subjected to temperatures greater than 55 °C and a hydraulic retention time of 6–15 days. Organic solids are degraded and the heat released during the microbial degradation maintains thermophilic temperatures.
