| Abstract |
| The purpose of this study was to understand the difference of removal characterics according to coagulant dose in the SBRFSP system. In this study, the Tertiary treatment 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 10ppm, polymer 1ppm) and condition 2(PAC 10ppm, Polymer 1ppm), the removal efficiency of SS has been revealed to 55.7% and 53.3%, respectively. And the removal efficiency of COD was 45.0% and 42.9%, respectively. Also, the removal efficiency of TN was 28.4%, 24.7%, respectively. For TP removal with the condition 1,2, the removal efficiencies of TP have been revealed as 67.1% and 53.3%, respectively. The TP removal efficiencies are improved to as 13.8% for condition 1 more than condition 2. |
