A master's thesis at the College of Engineering at the University of Basrah examined (the effect of the shape and arrangement of barriers on the performance of the sinter with barriers)

The thesis presented by the student Duha Muhammad Hadi included the use of the flocculation process to agglomerate very small solid suspended particles to form large and heavy particles that can be removed in the sedimentation process during an acceptable residence period. hydraulic

The thesis aims to conduct an experimental work to study the effect of the shape of the barriers and their arrangement on the performance of this sinter with baffles. Experiments with artificial turbid water

The study concluded that the efficiency of flocculation increases with the increase in the gradient of the speed until it reaches a maximum of it, and then it decreases and the values ​​of G that produce the maximum efficiency change with the change of the residence time, as it decreases with its increase. The correlation between efficiency and primary turbidity is weak to positive and represented by a logarithmic relationship
