Pengaruh Variasi Hrt Pada Reaktor Upflow Anaerobic Sludge Blanket (Uasb) Tahap Metanogenesis Menggunakan Bioball Untuk Pengolahan Palm Oil Mill Effluent (Pome)
ABSTRACT
Palm oil mill effluent (POME) contains high COD levels ranging from 38,080 to 44,928 mg/L. The appropriate method for treating wastewater with high COD concentrations is anaerobic treatment, one of which is using an upflow anaerobic sludge blanket (UASB) reactor. This reactor is effective in wastewater treatment and capable of producing biogas. This study aims to investigate the effect of HRT variations in the methanogenesis stage of a UASB reactor with bioball media on the efficiency of total COD, dissolved COD, TSS, TAV removal, VSS formation, SVI, and biogas production in POME treatment. The main experiment was operated continuously in a two-stage UASB reactor with a working volume of 17.5 L for the acidogenesis reactor and 4 L for the methanogenesis reactors (bioball and control). Before use, the inoculum source from secondary anaerobic pond sludge was cultivated through a seeding process for 12 days with a glucose
