A Performance Comparison of Anaerobic and an Integrated Anaerobic-Aerobic Biological Reactor System for the Effective Treatment of Textile Wastewater

The accumulation of recalcitrant azo dyes from untreated textile effluents has adversely impacted the ecosystem. immense stability in their nature is conferred by presence bonds (N=N) structure. reduction this bond occurs exclusively under anaerobic conditions giving rise to colorless aromatic amines, which are carcinogenic. In present study, a synthetic effluent containing mixed such as Reactive Red, Black, and Brown, was treated using activated sludge lab-scale sequential batch reactor (An-SBR). At concentration 100 mg/L dyes, An-SBR gave maximum 88% decolorization detected through UV-visible spectroscopy. Physicochemical analyses revealed 73% removal BOD, 90% TDS removal, 69% COD 4.05% TKN 66% chloride hardness removal. When increased 500 mg/L, treatment showed decrease efficiency. This then compared anaerobic-aerobic process performed laboratory-scale aerobic moving bed biofilm (MBBR). study that held more potential for commercial application than an process. metabolites formed during phase were extracted analyzed FT-IR HPLC identified GC-MS those found effluent. A phytotoxicity test conducted on remainder (secondary) Vigna unguiculata, it show 50% germination retardation root shoot length.
