  • In order to evaluate primary clarifier performance on TSS(Total Suspended solids) removal, four different sampling sets were collected as part of this study; (1) weekly test, (2) the diurnal sampling, (3) the settling velocity distribution sampling. Primary effluent TSS($TSS_{PE}$) and non settleable TSS($TSS_{NON}$) concentrations were averaged 160 and 75.5 mg/L, respectively. These data suggest approximately 85 mg/L TSS can be removed more. Average $TSS_{NON}$, $TSS_{PE}$, and Dispersed TSS(DTSS) concentrations(75.5, 160, and 104 mg/L, respectively) suggest that 28.5 mg/L of TSS difference attributable to poor flocculation, whereas 56 mg/L of TSS difference attributable to poor hydraulics within primary clarifier. In this study, equations for maximum TSS removal efficiency and effluent TSS concentration were suggested and compared with experimented data.
