Abstract

The potential of methane production in a continuously stirred tank reactor (CSTR) was investigated using dairy manure as inoculum at pH 6.8 and 37 °C temperature in this study. Two identical anaerobic bioreactors namely CSTR₁ and CSTR₂ filled with palm oil mill effluent (POME) as a carbon source were used. CSTR₁ was not added with the inoculum, while CSTR₂ was added with dairy manure as inoculum. Both the reactors were allowed to run for 5 days (d) in batch condition at hydraulic retention time (HRT) 10 d. The CSTR₂produced 0.85 L/d gas yield and 59% methane content compared to 0.39 L/d gas yield and 20% produced in CSTR₁, respectively. A better chemical oxygen demand (COD) reduction percentage of 48% was found in CSTR₂ compared to CSTR₁ with 33%. The investigation showed that dairy manure as inoculum has a marked influence on the start-up period and the biogas production rate.
