Pengaruh Variasi Laju Upflow Terhadap Pembentukan Biogas Pada Pengolahan Limbah Pome Menggunakan Reaktor Upflow Anaerobic Sludge Blanket

---

ABSTRACT
The chemical oxygen demand (COD) in palm oil mill effluent (POME) is
high 32000 mg/L allows suitable processing is anaerobic digestion because not
only control pollution but also provides valuable resources in the form of biogas.
This research aims to study the effect of upflow velocity variations to biogas
production, dissolved COD, bacterial growth through volatile suspended solid
(VSS), formation of volatile fatty acids (VFA), sludge volume index (SVI) and
changes in PH and temperature in the processing of POME using an upflow
anaerobic sludge blanket (UASB) with effluent recirculation on 10 L working
volume, ratio of inoculum: waste = 30:70%. Source inokulum used in the form of
bacteria mixed culture rumen beef which has been cultivated through the seeding
process for 5 days and the acclimatization I and II for 20 days and 50 days. The
research was done with varying the upflow velocity 0,6; 0,8; and 1 m/h with
hydraulic retention time (HRT) for 5 days. The results showed total and dissolved
COD allowance, and the highest biogas production occurred at an upflow rate of
0,8 m/h by 70,00%; 62,50%; 57,5 mL; and 667 mg/L sequentially with the lowest
concentration of micro-organisms in a VSS effluent of 1380 mg/L. The rate of
formation and efficiency of the highest VFA formation occurs at an upflow rate of
1 m/h 2023,25 mg/L/day and 64.44%. Sludge volume index (SVI) decreases with
the increase in upflow rate to achieve the lowest value at 0,8 upflow rate of 17,75
mL/g.
Keywords: upflow velocity, palm oil mill effluent, COD removal, biogas
