Abstract

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.
