ABSTRACT
Laboratory scale studies were conducted in an up-flow anoxic bioreactor [UFAB] using synthetic fertilizer wastewater for ascertaining the denitrification efficiency. The performance of the reactor was compared using ethanol and topioca starch as the carbon source. The initial NO3-N concentrations [50-250 mg/L] and hydraulic retention time [HRT, 12-24 h] were varied to evaluate the COD and NO3-N removal. The results from this study shows that ethanol gave very good denitrification efficiency [78-98%] compared to topioca starch [68-96%]
