Induced Air Flotation - separates suspended solids, oil,
The WaterTectonics Dissolved Air Flotation (DAF) system separates suspended solids, oil & grease, and other insoluble impurities from water slurries. The process dissolves air into water under pressure. Upon release of the pressure, micro-bubbles form. These micro-bubbles interact with the particles to cause them to float to the surface of a vessel where they are skimmed and
Water Treatment by Induced Air Flotation Using Microbubbles
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. That is to say, if the microbubble generator is utilized in

Induced gas flotation - Wikipedia
Induced gas flotation From Wikipedia, the free encyclopedia 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 water or wastewater in a flotation tank or basin.
TECHNICAL PAPER Induced Gas Flotation (IGF) within an API,
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 to the gas, a notable benefit to the IGF
Flotation Cell Design: Application of Fundamental Principles
a mechanical cell is a two-stage process. Firstly, air cavities are formedat the trailing edge of the impeller blades, which is the low pressure region. Thereafter, bubbles form by shedding of vortices from the tail of the cavity, as shown in Figure 3. Thedispersionof airintobubblescan becharacter-ized by three properties: bubble size, gas hold-up and superRcialgasvelocity,
