In this research, the decolourization process of Diamozol Red ED-3 textile dye by using activated sludge collected
from wastewater treatment facility in Bilecik First Organized Industry Zone was examined in membrane bioreactor (MBR)
system. The Lab/Pilot Scale MBR system had a working volume of 170 L and was equipped with a coarse and fine air bubble
creation mechanism for membrane and biological aeration, respectively. The temperature of the aeration tank was controlled at
25±1°C, the pH value and the concentration of DO was kept, respectively, in the range of 6.5-7.0 and 2.0-2.5 mg/L in the aeration
tank. The initial dye concentration and COD concentration of the synthetic wastewater prepared for decolourisation process were
50 and 952 mg/L, respectively. The dye concentration, COD concentration value were measured daily in effluent to assess the
removal efficiency. Most of the analytical techniques used in this study were mentioned in the standard methods. At the end of
the study treatment percentage colour removal was approximately 76% and COD removal was 79% in 7 days. The results
obtained from this study showed that textile dyes can be effectively decolorized by the activated sludge in MBR system.
