Abstract

Patchouli oil distillery waste (PODW) was used as a substrate for methane production in wet semi-continuous and dry batch anaerobic digestion (AD). In wet semi-continuous AD, the system was operated with recirculation of effluent. Two reactors with 300 mL of working volume were operated for 45 days in three moderate stepwise-increased organic loading rates (OLR), which were 0.5, 1, and 2 g VS/(L.day). Wet semi-continuous AD with recirculation produced the highest methane production at OLR of 1 g VS/(L.day), which was 13.71 ± 2.28 (Nml/g VS). In dry batch AD, three different values of VS, which were 1.5 g VS; 3 g VS; and 6 g VS, were mixed with inoculum, after which distilled water was added to adjust the TS content in the reactor up to 17; 12; 20; 15; 26; and 21%. The experiments were conducted for 47 days. The highest methane yield of 13.87 ± 0.99(Nml/g VS) was obtained with TS 17% of 1.5 g VS.
