A Sequencing Batch Reactor (SBR) was used to reduce the concentration of organic parameters, that consisted of Chemical Oxygen Demand (COD), Total Nitrogen (N Total) and Total Suspended Solid (TSS) in an apartment wastewater, because the SBR system had a high space efficiency and was low in cost. The apartment wastewater was especially from the effluents of water closets and kitchen. In this study, we applied the SBR method and added activated carbon powder to treat apartment wastewater which had previously gone through the first settling process. This SBR was operated with various hydraulic retention times (HRT) which were 12, 24 and 36 hours respectively, and aeration rates of 3.5 and 7 L/min. Dissolved Oxygen (DO) testing was carried out at each stage of SBR, which aimed to measure and maintain stability at each stage of SBR. The results of the study were the optimum HRT and aeration rate, which were 36 hours and 7 L/min respectively. FTIR test was carried out to determine the efficiency of activated carbon addition in this SBR process. It was found that Activated Carbon increased SBR performance as evidenced by the COD removal rate reaching 89.5% and Total N 94.54%.
