بيت /induced air flotation
This work presents a discussion of the induced gas flotation process as a method for cleaning waste waters by removing suspended contaminants using froth flotation. The origin of the process is briefly reviewed, and a comparison is made to dissolved air flotation showing that the 2 processes have both similarities and differences.

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 air bubbles into the water or wastewater in a flotation tank or basin.

Separation by induced air or gas flotation is a process used in many oily water treatment. The bubbles of air or gas are introduced violently into water via turbines cyclones. Oil surrounds the air bubbles and goes up on the surface in the form of scums where it is recovered by selfadjustable skimmer.

Induced Gas Flotation (IGF) and Induced Static Flotation (ISF) units provide a more enhanced approach to oil removal through the addition of gas bubbles to aid in the flotation of oil to the surface. Gas, which is typically induced by sparging tubes or eductors, floats the oil .

Air flotation can separate solids and liquids by having gas bubbles attach to the solid particles to increase buoyancy and lift them to the surface. The small particle sizes of algae require that small bubble sizes be used. Conventionally very fine bubbles are created using dissolved gas flotation DAF).

Finally, dissolved air flotation may occur by trapping both gas bubbles and solid materials in a floe structure. This process (3) occurs after the pressure is released and the gas is coming out of solution. Air To Solids One of the primary operating variables of a dissolved air flotation system is the air .

A very similar process known as induced gas flotation is also used for wastewater treatment. Froth flotation is commonly used in the processing of mineral ores. In the oil industry, dissolved gas flotation (DGF) units do not use air as the flotation medium due to the explosion risk. Natural gas is used instead to create the bubbles.

• induced Air Floatation (IAF): a variant of the DAF unit that is commonly used in oil fields and for ballast water treatment. COMPACT FLOTATION UNITS Increasingly stringent environmental discharge requirements plus the constant pressure to reduce equipment footprint have led to the development of the Compact Flotation Unit.
