Flotation can be combined with coagulation and flocculation wastewater treatment methods. DAF is a liquid-solid separation method that involves solubilizing air in water employing high pressure (around 400–600kPa) after releasing the supersaturated water in a flotation cell through needle valves or special orifices.
