This study examines the impact of organic loading rate (OLR) on the effluent quality and sludge settling performance in a sequencing batch reactor. Four SBR reactors were used in this study; the working volume of each one is 5l. The reactors were operated under different potassium nitrate concentrations (50, 100, 150 and 200 mg/l), constant aeration, 1.0 l/min, ±20 Cº temperature and 6 h cycle time. Each cycle of the SBR operation included Fill (30 minutes), React (240 minutes), Settle (30 minutes), Draw (30 minutes) and Idle (30 minutes). Influent and effluent samples were analysed for NH3-N to determine the removal efficiency. In addition, the sludge volume index (SVI) was used to study the sludge characteristics. The results obtained from this study, which operated for 60 days, showed that the sequencing batch reactor could biodegrade up to 91.5% for NH3-N with potassium nitrate concentration between 50 and 150 mg/l, and a steady sludge settling performance occurred during that range.
