Pengaruh Kecepatan Pengadukan Dan Waktu Pengendapan Menggunakan Sequencing Batch Biofilm Reactor (Sbbr) Untuk Pengolahan Limbah Cair Domestik

ABSTRACT
Greywater is a waste from kitchen, bathroom, and laundry activities that contains
high organic matter. The organic matter contained in the wastewater is utilized by
the microalgae Chlorella sp. as a source of nutrient and its reduce the pollutant in
wastewater. This study aims to count the number cells of Chlorella sp. which grew
in suspension and attached to the Kaldness 1 (K1) biocarrier media and the
removal of COD and NH3 in domestic wastewater using Sequencing Batch
Biofilm Reactor (SBBR). The SBBR was operated on 4 cycles consisting of 30
minutes of filling time, 120 minutes of reaction, 45 minutes of decanting, and 120
minutes of stabilization time. This research was carried out with a working
volume of 5 liters, 30% K1 kaldness media, and 25% suspended microalgae
concentration with variations in stirring speed (40 , 60, and 80 rpm) and
variation of settling time (30, 45 and 60 minutes). The best results showed a
decrease in COD and NH3 variations in stirring speed of 60 rpm and settling time
of 60 minutes, COD removal efficiency was 78% from the initial COD
concentration of 288 mg/L to 64 mg/L and NH3 removal efficiency was 80.6%
from the initial concentration. 13.25 mg/L to 2.58 mg/L.
Keywords: SBBR, Domestic Wastewater, Chlorella sp., Biocarrier Kaldness 1
