| Abstract | The potential of removal of carbon, nitrogen, phosphorus and azo dye in a sequencing batch reactor was studied with five liter capacity single tank using synthetic wastewater. Reactive red 22, azo dye was subjected for biodegradation along with biological nutrients. Twenty four hour single cycle operating pattern was applied to enhance color and phosphorus removal. Batch runs were analyzed for the increasing dose of azo dye and ammonium. Up to the ammonium dose of 40 mg/l, complete decolorization of synthetic wastewater was observed. Phosphorus removal, up to dose of 15 mg/l was in range of 69% to 100%. COD removal was 93% to 97% in single feeding and 87% to 95% in double feeding. Once the ammonium concentration was increased to 45 mg/l decolorization was inhibited due to formation of nitrate subsequently phosphorus removal was hindered. Simultaneous removal of carbon nitrogen, phosphorus and azo dye is attained for lower concentration of nutrients and azo dye. The inhibition in azo dye decolorization indicates that the selected operating pattern is not sufficient for degradation of azo dye in higher ammonium nitrogen concentration. |
