Abstract

A mathematical model is used to examine the effect of inlet and outlet deflectors on the hydraulic characteristics and the concentration field of the suspended solids in primary settling tanks. From the application of the model to a typical settling tank consisting of an inlet slot , an outlet weir, an inlet and an outlet deflector, it is concluded that the hydraulic characteristics and the suspended solids removal efficiency of the tank improves by the use of an inlet deflector, whose position (distance and submersion) is not very critical The effect of an outlet deflector is of minor importance. 1 Introduction Several types of inlet and outlet configurations of settling tanks have been proposed in the past by vari
