Abstract The objective of this study was improvement of removal efficiency in rectangular sedimentation basin. By revealing the relation between the water temperature and the water flow in the sedimentation basin, when flow rate and sedimentation basin volume are constant, the efficiency of sedimentation basin is preportional to the real retention time in basin. The real retention time by installing diffuser walls and locating overflow weir was investigated by dye-flow and effluent dye-concentration. Density flow could be controlled by diffuser walls. In case of installing diffuser walls to every overflow weir of four piece in equal space arranging, the removal efficiency was improved by placing the first weir from the 60% position flow direction.
