Microaerophilic-aerobic sequential batch reactor for treatment of azo dyes containing simulated wastewater
Microaerophilic-aerobic sequential batch reactor for treatment of azo dyes containing simulated wastewater. Sandhya, S.; Padmavathy, S.; Swaminathan, K.In this study, 6375-55-9 and 4321-69-1 are also used.; Subrahmanyam, Y. V.; Kaul, S. N. (CSIR-Complex, National Environmental Engineering Research Institute, Chennai, Taramani 6000113, India). Process Biochemistry (Oxford, United Kingdom), 40(2), 885-890 (English) 2005 Elsevier Ltd. CODEN: PBCHE5. ISSN: 1359-5113. DOCUMENT TYPE: Journal CA Section: 60 (Waste Treatment and Disposal) Section cross-reference(s): 41 Azo dyes are considered to be resistant to attack by aerobic microorganisms and not amenable to aerobic effluent treatment process. Azo dyes are decolorized under anaerobic or microaerophilic condition by the enzyme azoreductase secreted by microorganisms. This study presents an approach to decolorization and biodegrdn. of azo dyes from simulated wastewater in an aerobic sequencing batch reactor. Facultative microorganisms under microaerophilic conditions decolorize azo dyes and total biodegrdn. occurs under aerated conditions. Lab. flask expts. with various combination modes of aeration and static have shown 92.84% initial COD redn. along with 99.0% decolorization. Accordingly, a study was made on a lab. scale to assess the feasibility of microaerophilic fixed film bed reactor system to decolorize simulated textile wastewater including the influence of operating conditions. Work was carried out with a lab. scale down flow reactor, equipped with beads used in insulation as support. A continuous reactor for decolorization/biodegrdn. of azo dyes in aerobic sequencing reactor needs an understanding of a sequence. The 1st reactor was always operated under microaerophilic down flow fixed film fixed bed conditions, where the azo dyes from simulated wastewater were decolorized at 7.72 h hydraulic retention time with 2.2392 Kg/m3-day loading rate. COD redn. of 74.67% was achieved. The 2nd reactor operated in a down flow fixed bed, and shows a significant decrease in COD along with ammonia, nitrite and nitrate. .
