Induced Gas Floatation Principle
Induced Gas Flotation IGF
· In the induced gas flotation (IGF) (or IAF) process, which resembles the design of a subaeration minerals flotation cell (see Figure 2), bubbles are induced mechanically. IGF uses a starshaped impeller to generate intense local turbulence. This results in subatmospheric pressures being generated in the region surrounding the impeller which causes gas to be induced from the gas space .

INDUCED GAS FLOTATION
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 liquid in a flotation tank or basin. The small bubbles adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be ...

Numerical analysis on performance of induced gas flotation ...
An induced gas flotation (IGF) machine is a type of water treatment equipment that separates oil droplets or particles from wastewater using the characteristics of floating air bubbles. In general, bubble movement inside an IGF is difficult to predict since the internal flow in an IGF is not linear due to vortex formation and recirculating flow. Furthermore, the actual bubbles are distributed ...
