Proses Penyisihan Cod Pada Tahap Asidogenesis Pengolahan Palm Oil Mill Effluent (Pome) Menggunakan Reaktor Upflow Anaerobic Sludge Blanket (Uasb)

---

Palm Oil Mill Effluent (POME) contains high chemical oxygen demand (COD) of 33.600 mg/L. POME contains high concentrations of organic matter and if not treated can be damage to the environment. The most suitable treatment is anaerobic treatment using an upflow anaerobic sludge blanket (UASB) reactor. The purpose of this research is to study the effect of hydraulic retention time (HRT) variation in the acidogenensis stage on the removal of total COD, dissolved COD, bacterial growth through volatile suspended solid (VSS), total volatile acid (TAV) formation, biogas production, sludge volume index (SVI), and pH changes. Main research was carried out using a UASB reactor with a working volume of 17,5 L, waste:inoculum ratio = 70%:30%. Before use, the inoculum source was bacteria from a UASB reactor operating for 4 years that was used by previous researchers who also treated POME and was cultivated through a seeding and acclimatization process for 33 days with a glucose concentration of 25,000 mg/L. The study was conducted by varying the HRT of 4, 6, and 8 hours with flow rates of 4.38; 2.92; and 2.19 L/h respectively. The results showed the highest total and dissolved COD removal at HRT 8 hours with an average removal efficiency of 60% and 57.1%, VSS growth of 10 g/L and SVI of 41.7 mL/g, and the lowest TAV formation efficiency of 45.7%.
