Title: Floatation

Dissolved Air Flotation (DAF)

Sin título Text

In this system, the air is introduced into the wastewater under a pressure of several atmospheres. The main elements of this equipment are the pressurization pump, the air injection equipment, the holding tank or saturator, and the flotation unit itself, where the sudden reduction in pressure takes place so that the dissolved air is released, forming a multitude of air micro bubbles (El-Gohary et al., 2010)

Induced air flotation

Sin título Text

The operation is similar to the previous case, but the generation of bubbles is carried out through air diffusers, normally located in the lower part of the flotation equipment, or induced by rotors or agitators. In this case, the size of the induced bubbles is greater than in the previous case (El-Gohary et al., 2010).
