Abstract: The idea for energy efficiency improvement in Autothermal Thermophilic Aerobic Digestion (ATAD) batch processes follows the observation that the fresh sludge load to bio-treatment reactors causes a thermal shock of microorganisms. This study focuses on opportunities for the thermal shock reduction in conventional ATAD systems through recovery the heat from the effluent stream, which can lead to substantial savings of the time required for operating temperature recovery, less foaming and quicker bio-degradation. Mathematical model for energy integration of ATAD system using two heat storage tanks is proposed. Solution of the formulated optimization problem gives a response for energy efficiency improvement and thermal shock reduction in bioreactors.
