The objective of the present work is to develop a two dimensional numerical model to predict the performance of the sedimentation basin in Al-Karamah treatment plant and consequently to increase the basin efficiency. The mixture model adopted by COMSOL Multiphysics is applied coupling with k-epsilon turbulent model. The model showed that particles commence out from the basin after 5 min and it commence to collect at the sludge zone after 1.6 hr. The model demonstrated the important role of SOR on the performance of the sedimentation basin. Also, the result showed that the removal efficiency increases with a decrease of SOR. The relationship between SOR and removal efficiency is nonlinear second order equation with R2 equal to 0.999. Finally, numerical results demonstrated that the effect of the installation of conical reaction wall on the settling behavior is very small and negligible.
