    abstract = {The performance of an aerated submerged fixed film bioreactor was evaluated during 45 days. High
ammonia loading in domestic wastewater from a huge industry was used as the influent of the experiment. A
laboratory experiment was conducted using a bioreactor with 5.6 L capacity operated at different hydraulic
retention times which were 6, 8 and 10 h. Return activated sludge from wastewater treatment plant of Jababeka
was taken as seed sludge. The influent of the experiment has Chemical Oxygen Demand (COD) loading rate from
1181-1987 g COD m<sup>&#150;3</sup> day<sup>&#150;1</sup> and ammonia loading from 134-223 g NH<sub>3</sub>-Nm<sup>&#150;3</sup> day. Results indicated better
performance at 10 h retention time that the system was able to achieve 90-93 and 94-99% removal efficiencies
of COD and ammonia. Data gained exhibited the R<sup>2</sup> value were 0.87 and 0.85, respectively. The effluent COD
an ammonia concentration ranged between 36-60 and 0.4 5 mg/L which lower than the Indonesian national
discharge standards which were 80 mg COD/L and 10 mg NH<sub>3</sub>-N/L. The present study showed also two conditions of aerobic and anaerobic could be worked in a single bioreactor.}
