Abstract
CHARACTERIZATION OF CELLULAR BIOMASS PRODUCTS IN MEMBRANE BIOREACTOR IN AZO DYE REMAZOL BLACK 5 BIODEGRADATION.In this study the characterization of cellular biomass products in anoxic-oxic membrane bioreactor (MBR) in azo dye Remazol Black 5(RB 5) biodegradation in the low solid retention time (SRT) was evaluated. The MBR consists of anoxic-, contact-, and stabilization tank and was equipped with an external polysulfone membrane which placed between the contact and the stabilization tanks. Feed was the mixture of azo dye RB with a concentration of 120 mg/L and co-substrate tempe industrial wastewater with COD ranging between 2,080-2,400 mg/L. With a combination of filtration and backwash time of 1 hour and 1 minute, the MBR was operated for 50 days with an average flux 9 lmh and pressures of 0.8 to 2 bars. The cellular components of each tank were measured as extracellular polymeric material (EPS) and soluble microbial products (SMP). The color removal efficiency was in the range of 66-77%, while COD removal efficiency i.e. 44-50%. Unfavorable biomass transfer between tanks may decrease the organics removal of MBR, neverthelessthis transfer does not affect the EPS. The carbohydrates content of the SMP and EPS from each tank was higher than that of the the protein content. Carbohydrates coming from the hydrolysis productsseem the main cause of the fouling compared to the proteins. The high concentration of the EPS was in the stabilization tank due to the poor oxygen transfer within the biofilm structure while passing through the membrane.
