sequential anoxic moving bed bioreactor (AnoxMBBR) and aerobic continuous stirred
tank reactor (AeCSTR) to remove chemical oxygen demand (COD) and
ammonium-nitrogen from landfill leachate. The sequential AnoxMBBR /AeCSTR
system was tested at constant hydraulic retention time (HRT) of 48. The
performance of this system was evaluated in terms of chemical oxygen demand
(COD), ammonium (NH <sub>4 </sub> <sup>+ </sup>), nitrite (NO <sub>2 </sub> <sup>- </sup>)
and nitrate (NO <sub>3 </sub> <sup>- </sup>) parameters. In AnoxMBBR, nitrate
removal (40%) was limited due to low COD removal efficiency. In AeCSTR, COD and
ammonium removal efficiencies were obtained as 46% and 71%. Also, partial
nitrification in AeCSTR was simultaneously achieved with nitrite accumulation
of 1660 mg/L. The results indicated that the AnoxMBBR/AeCSTR system is quite
efficient to remove COD and ammonium from landfill leachate, however, the
effluent COD and ammonium concentration still did not meet the discharge
criteria. </span> </p> <p> </p>}
