The performance of a rectangular settling tank with two effluent system is described by hydraulic laboratory experiments. The velocity profiles of neutral current by dye tracer method and LDA describe the effect of the two effluent system. The proper location of a baffle may be determined by using flow-through curves from dye tests. The experiments using the clay turbid water as settling suspension show that the overflow rate, the installation of baffle and the location of effluent are crucial influential factors on removal efficiency.
