Municipal Wastewater Treatment by Sequencing Batch Reactor

The report presents municipal wastewater treatment using Biological process by Sequencing Batch Reacror (SBR). The aim of the study is to investigate the SBR on the removal of organic compound and nutrient namely nitrogen and phosphorus. Lab scale SBR model with the presence ~f anoxic-aeration state was operated in 5 state of cycle in SBR which are the Filling, React, Settle, Decant and Idle period. Effluent discharged during the Decant state have resulted a high quality ef!luent with low concentration of COD, TSS and annnonia and nitrate. The removal of COD, TSS, ammonia and nitrate was 69.4%, 47.67%, 86.07% and 59.16% respectively. The optimum parameter was evaluated based on the perfOrmance at various rates. Hydraulic Retention Time (HRT) of the SBR cycle at 17.22 hours results in the optimum removal reduction of nitrogen
