PENGARUH VARIASI KONSENTRASI AIR LIMBAH TERHADAP PEMBENTUKAN MICROALGAL-BACTERIA GRANULAR SLUDGE (MBGS) DALAM PENGOLAHAN AIR LIMBAH DOMESTIK

Domestic wastewater is a complex environmental problem that requires
effective treatment technologies. The most widely used biological treatment today
is Conventional Activated Sludge (CAS), but CAS has shortcomings such as poor
sludge settling performance, high energy consumption, requires a large area, long
hydraulic retention time, produces CO2 gas and produces excessive sludge and low
removal efficiency. A new innovation in wastewater treatment is using MicroalgalBacterial Granular Sludge (MBGS). Domestic wastewater contains organic carbon
(C), nitrogen (N), and phosphorus (P) which can be utilized in the formation of
MBGS. This research aims to identify indigenous bacteria in domestic sewage
sludge, study the effect of variations in sewage concentration on the formation and
characterization of MBGS and the performance of MBGS in the removal of COD
and ammonia from domestic wastewater. This study used Photobioreactor (PBR)
with 3 variations of waste concentration namely PBR 1 (300±50 mgCOD/L), PBR
2 (700±50 mgCOD/L) and PBR 3 (1,000±50 mgCOD/L). The results of bacterial
identification obtained 7 indigenous bacterial isolates consisting of 6 Gram
negative bacteria and 1 Gram positive bacteria. The best results were shown in
PBR 3 (1,000±50 mgCOD/L) which has a compact and dense structure with the
characteristics of size, VSS, SVI5, SDI, COD efficiency and ammonia sequentially,
namely, 0.9-1.5 mm; 6.27 g/L; 26.8 mL/g; 2.71 g/L; 97% ;97%.
