Özet
This study evaluates the effects of ultrasonic and thermal pretreatment on apple pomace solubilization and on the performance of the subsequent mesophilic anaerobic digestion. Ultrasonic frequency (35 and 53 kHz) and thermal methods are studied for pretreatment strategies. For each pretreatment method, four different temperatures are selected such as 25, 40, 50, and 60 degrees C, and operation times are selected as 5, 15, 30, and 45 minutes. The highest increase in organic solubilization was observed at 60 degrees C with 53 kHz in the 45 minutes. The highest biochemical methane productivity was achieved by the 53 kHz ultrasonic pretreatment at the 45 min. In addition to this, the solution with 1481.4 mL CH4/g-VS was 1.74 times higher than the nonpretreatment condition 852.8 mL CH4/g-VS. The pretreatment tests showed that the increasing biochemical methane potential could be obtained by using the apple pomace.
