N2 - Thermal pre-treatment is necessary for the feedstock of Anaerobic Digester (AD) to improve the degradation process. This study aims to investigate the effect of thermal pre-treatment on Food Waste (FW) as a substrate through Biochemical Methane Potential (BMP) test followed by pilot scale using a continuous stirred tank reactor (CSTR) digester. TS, VS, COD, SCOD, and solubilization samples were measured during on CSTR reactor. FW was pretreated by heating at 70 °C, 90 °C, and 120 °C for 45 minutes. Results showed that thermal pre-treatment at 70 °C had the most effective digestion process with TS, VS, COD reduction of 8.26%; 2.54%; and 14% and increase SCOD and solubilization of 10.2% and 24.7%, respectively compared to thermal pre-treatment at 90 °C and 120 °C (p<0.05). Therefore, thermal pre-treatment at 70 °C was chosen for AD pilot scale in this study. Meanwhile, pilot scale experiment showed the results that thermal pre-treatment at 70 °C was obtained significant differences of 31% TS; 38% VS; 42% COD; 23% SCOD; and 30% solubilization compare with without thermal pre-treatment (p<0.05). Pre-treatment with thermal on FW as a substrate may help in increasing the degradation process at the hydrolysis phase in order to increase the effectiveness of the process in AD reactor.
