Induced Gas Floatation Principle

Dissolved Air Flotation (DAF) is the process of removing suspended solids, oils and other contaminants via the use of air bubble flotation. Air is dissolved into water, mixed with the wastestream and released from solution while in intimate contact with the contaminants.

Gas Flotation. The key to efficient operation of the gas flotation vessel is to control the bubble size and induce the correct amount of swirl. Gas Flotation Vessels require a certain quantity of gas in the feed to act as flotation gas. This can be provided either as a direct fuel gas feed, or gas can be recycled around the vessel using an educator loop.

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 ...
