Two-stage anaerobic digestions have been established to improve overall performance of sludge treatment. Temperature phase anaerobic digestion (TPAD) was often used as the first stage as pre-treatment of sludge at thermophilic temperature for short SRT followed by mesophilic temperature at longer SR...
