There are many wastewater treatment processes combining different unit process to improve dissolved and suspended pollutants recently. In this study, the domestic wastewater system could be carried out with the SBRFSP(sludge blanket rapid flocculation sedimentation process). The following conclusions can be drawn from the study: In the SBRFSP system treatment characteristics, in the operating condition 1(PAC 60ppm) and condition 2(PAC 45ppm. Polymer 2), the removal efficiency of SS has been revealed to 95.0% and 95.2%, respectively. And the removal efficiency of COD was 56.6% and 55.3%, respectively. Also, the removal efficiency of TN was 22.7%, 23.0%, respectively. For TP removal with the condition 1.2, the removal efficiencies of TP have been revealed as 59.5% and 65.0%, respectively. The TP removal efficiencies are improved to as 5.5% for condition2 more than condition1.
