Induced air flotation IAF was developed using a rotating-flow microbubble generator for water treatment. This newly-developed generator can produce fine microbubbles with diameters on the order of micrometers, whereas it has to use a large quantity of water as propulsion, especially when surfactant-free water is used.
ESI has spent years improving traditional equipment such as our Skim Pile open drain sump caisson, Quadair induced gas flotation unit IGF and corrugated plate interceptors CPI while continuing to develop new products such as the patented Spiral Ramp LQ-R Hydrocyclone and VertiFloat vertical Compact Flotation Unit CFU.

ABSTRACT. Oil removal from actual produced water was studied in a full-scale four-cell induced gas flotation IGF machine. Objectives were to determine which parameters were influential in IGF oil removal performance, develop oil removal efficiency models as a function of these parameters, and predict machine settings for optimal performance. The influential variables,
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 to the surface, which can then be skimmed off. In addition

A very similar process known as Induced Gas Flotation IGF and Dissolved Gas Flotation DGF are also used for wastewater treatment in the oil industry where atmospheric air is substituted with Nitrogen gas to reduce the risk of explosion. Froth flotation is commonly used in the processing of mineral ores.
The innovation behind Suspended Air Flotation SAF was invented by the late Dr. Felix Sebba in 1975. Since then, the engineering and science team at Heron Innovators has advanced this technology establishing flotation without dissolved air as the next level in liquidsolid separation for water and wastewater treatment and solids thickening.
The Dissolved Gas Flotation produces much higher separation efficiencies than the traditional induced gas flotation units. During more than 40 years of experience in the treatment of oily water, Peerless through its Skimovex range has developed a tremendous knowledge in designing, engineering and supplying the right DGF unit for each ...
disposal. Induced gas flotation IGF systems are sepa-rators that can be used to clean the oily water to the required purity level. These systems work by introduc-ing small gas bubbles, 100 to 500 microns in diameter, into the vessel along with the contaminated water. The hydrophobic oil droplets and oil-coated solids attach to

The Quadricell separator is ideal for use where oilwater separation is required in large volumes, or where other organic matter must be removed from water or industrial effluents. For the removal of volatile organic compounds
suitable size for effective induced gas flotation IGF as a key performance parameter. The simulations further showed the need to generate the gas bubbles within the vessel instead of externally, and to introduce the gas bubbles in a radial pattern. Accordingly, a parallel development effort was instituted to develop the radial eductor.
