PENGARUH VARIASI KONSENTRASI LIMBAH TERHADAP KINERJA GRANULAR INDIGENOUS MICROALGAL-BACTERIAL CONSORTIUM (G-IMBC) DALAM PENYISIHAN COD DAN NITROGEN TOTAL DARI PALM OIL MILL EFFLUENT (POME)

Indonesia's palm oil industry has increased by an average of 8% per year, resulting
in an increase in wastewater. The production of one ton of palm oil will produce
2.5 tons of wastewater or Palm Oil Mill Effluent (POME) which is treated with an
open pond system. The open pond system still leaves greenhouse gases (GHG) and
nutrient content that can be utilized in the formation of Granular Indigenous
Microalgal Bacterial Consortium (G-IMBC). This study aims to identify indigenous
microalgae and bacteria in POME, analyze the characteristics and performance of
G-IMBC in pollutant removal. This study used a photobioreactor (PBR) with 3
variations of substrate concentration, namely PBR 1 (300±50 mgCOD/L), PBR 2
(750±50 mgCOD/L) and PBR 3 (1,200±50 mgCOD/L). The identified indigenous
microalgae consisted of Chlamydomonas sp, Chlorella sp, Euglena sp, and
Oscillatoria sp. The results of bacterial identification obtained 6 indigenous
bacterial isolates consisting of three bacillus-shaped gram-positive bacterial
isolates, namely PM-3. PM-5, and PM-6, one isolate of coccus-shaped gramnegative bacteria, namely PM-1, and two isolates of bacillus-shaped gram-negative
bacteria, namely PM-2 and PM-4. The best results were shown in PBR 2 with
variations in substrate concentration of 750±50 mgCOD/L. The G-IMBC formed
had a compact and solid structure with a granular diameter of 1-1.22 mm, VSS of
9.91 g/L, SVI5 of 37 mL/g and density of 2.71 g/mL with COD and total nitrogen
removal efficiency of 95.74% and 98.95%.
