- Sludge from flocculator outlet of PUSRI-III settles along the channel and generates a problem in wastewater treatment. Aims of this research were to obtain sedimentation characteristics and variables which influenced sedimentation efficiency and to minimize slurry flow into the biological pond. This reseacrh was conducted using vertical sedimentation steel column of 10 inchi diameter and 4.50 m long.. A 0.50 inch valve was installed as sampling tool along the pipe in every 500 mm distant. Settling efficiency was measured at intention time range of 10-50 minutes using initial concentrations of solid particles of 400, 420, 440, 460, and 480 mg/L. results of this study showed that settling efficiency could reach 60%-80% in retention time range of 2-40 minutes. Sedimentation rate of solid particles was not significantly influenced by the variation of initial concentration of solid particles. Results from this reseacrh can be used as a reference for sedimentation column design at flocculator outlet.
