Sep 12, 2013· Induced gas flotation (IGF) is a treatment process that clarifies wastewaters (or other waters) by the removal of suspended oil.The removal is achieved by introducing very small bubbles of air or other gases into the water or wastewater. The bubbles adhere to and enhance the buoyancy of the suspended oil which accelerates the rate at which the oil floats to the surface of the water where it ...

Induced gas flotation - Wikipedia

Induced Gas flotation is a secondary separation technology used for the removal of dispersed oil in produced water. Ovivo-Float IGF designs optimize the principles of Stokes law by using finely dispersed gas to reduce the apparent density of the oil and solids; increase their droplet size and greatly increase buoyancy through coalescence.

The apparatus used is generally termed a flotation cell and when surface-active agents, such as 'collectors' and frothing agents, are employed, the process is known as froth flotation. Alternatively, a gas and liquid stream may be homogenized or air may be diffused through suitable porous media. Dispersed-air flotation systems produce air
