Piggery Slurry Composting Using Batch Operating Autothermal Thermophilic Aerobic Digestion System
The performance of an autothermal thermophilic aerobic digestion (ATAD) system was studied to determine if nitrogen loss, as ammonia, was affected by an exhaust gas condenser. The system was run with and without a condenser while treating 8 m 3 of piggery slurry for 8 days.

Operation scheduling of batch autothermal thermophilic aerobic digestion processes
Abstract The autothermal thermophilic aerobic digestion (ATAD) is an exothermic batchwise operated sludge treatment process, in which sludge undergoes heating and pasteurization as temperature attains values about 50–60 °C. Based on detailed process models, different approaches have been suggested (Rojas and Zhelev, 2009) to minimize the specific ...
