    Specifically, CFD models offer advantages for the study of the dissolved air flotation (DAF) technology (Amato and Wicks 2009). On the one hand, these models are able to describe the solid separation process based on the hydrodynamics. This allows finding optimum load rates or reactor geometries to guarantee the maximum separation efficiency.
