Air flotation, in all its variations, is an efficient way to extract oil from wastewater. If the wastewater is chemically pretreated to break the oil emulsions, air flotation units are capable of removing most of the emulsified oil in addition to the free oil. This chapter covers various flotation techniques to achieve oil/water separation.

An alternative method of flotation is "dissolved-air flotation" (DAF), which is much more common in water treatment than induced-air flotation. In DAF, a stream of water is saturated with air at an elevated pressure of the order of 4 atm. The stream is injected into a tank, but customarily there is a continuous flow of the process water ...

Wastewater Treatment Superficial Air for Backwash Water Treatment Dissolved Air Flotation. Product description In the daf treatment for waste water, tiny bubbles are generated and mixed with the incoming waste water. Bubbles attach to pollutants, making them buoyant. The buoyant mixture of particles and bubbles floats on the surface and is ...
An Induced Gas Flotation (IGF) machine is a water treatment device that utilizes the flotation characteristics of air bubbles (Yiantos, 2007 ). The working principle of an IGF is that air bubbles are directly injected into the vessel and forced through a flow passage. Then, the discharged air spreads through the entire IGF vessel via a rotor.

Dissolved air flotation (DAF) is a water treatment process designed to remove oils, solids, and greases. In fact, the process helps clarify wastewaters – and other waters – by eliminating different types of suspended matter. The DAF process dissolves air in the water under pressure – then releases it at atmospheric pressure.
