Dissolved Air Flotation

One of the well known intermediate stages to treat water and wastewater is Dissolved Air Flotation (DAF). In order to design an efficient DAF unit, it is important to study the system and get familiar with the flow structure in it. Computational Fluid Dynamics (CFD) is used as a tool to study a flotation unit.
