Furthermore the sedimentation tank would be drained and cleaned less often because a floc weir constantly removes flocs from the top of the floc blanket and flocs would no longer settle to the bottom of the tank Our underlying goal is to understand how we can form floc blankets in a scaled model and to identify the geometric parameters of the sedimentation tank that enable floc blanket
