Abstract: Although, the principle of settling has been known for a very long time, it becomes very complex in the case of sedimentation of more or less flocculated particles, due to the change in the initial physical properties of the particles (shape, diameter and density). A hydrodynamic model of a new settling basin is developed on a reduced model where length is 1.7 m , 0.6 m in width and 0.3 m in theoretical settling height. A comparison of the water flow velocities within the structure with the measurements simulated by the Ansys Fluent computer code is carried out, with several construction features in order to improve its hydraulic and hydrodynamic performance. A better distribution of velocities is obtained by the device called 3 axes.
