Flotation: DAF, IAF, SAF - Veolia Water

3. Induced air flotation (IAF) involves saturating the wastewater with air either directly in an aeration tank or by permitting air to enter on the suction side of a pump or with a venturi. The partial vacuum, which is applied, causes the dissolved air to come out of solution as minute bubbles. 4. Suspended air flotation (SAF) is a newer ...

Induced gas flotation - Wikipedia

Induced gas flotation (IGF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by injecting gas bubbles into the water or wastewater in a flotation tank or basin.

Dissolved air flotation - Wikipedia

Dissolved air flotation is very widely used in treating the industrial wastewater effluents from oil refineries, petrochemical and chemical plants, natural gas processing plants, paper mills, general water treatment and similar industrial facilities. A very similar process known as induced gas flotation is also used for wastewater treatment.

4-flotation.ppt | Applied And Interdisciplinary Physics ...

Flotation. Flotation involves separation of solids from the water phase by attaching the solids to fine air bubbles to decrease the density of the particles so that they float instead of sinking. The rising solids are called the "float". The float is skimmed off the surface and further processed in the sludge train.. Advantages of flotation over sedimentation:

Dissolved Air Flotation - School of Civil & Environmental ...

Types of Flotation Different methods of producing gas bubbles give rise to different types of flotation processes. These are electrolytic flotation, dispersed air flotation, and dissolved air flotation. The basis of electrolytic or electroflotation is the generation of bubbles of hydrogen and oxygen in a

Induced Gas Flotation - processgroupintl.com

Induced Gas Flotation D.04 Introduction Induced Gas Flotation (IGF) is a well-proven method of oil recovery in water treatment applications. IGF Units are used extensively around the world for the recovery of oil from produced water streams in a wide range of applications at onshore and offshore production and processing facilities,

A Study of Kinetics on Induced-Air Flotation for Oil-Water ...

Abstract Induced-air flotation makes use of the centrifugal force of a high-speed backspin impeller through which gas is introduced at the top and liquid at the bottom. The gas and liquid become fully intermingled and, after passing through a disperser outside the impeller, form a multitude of gas bubbles, thus completing the flotation separation process of a liquid-solid or liquid-liquid ...
