This process is called dissolved gas flotation ( DAF). However, in minerallurgy and in the oil industry, when air or any other gas is dispersed and produce fine bubbles measuring 0.2 to 2 mm in diameter, this is termed induced air flotation ( IAF ) or induced gas floatation ( IGF ). relationship between design and bubble velocity
Flotation is a widely used, cost-effective separation technique for wastewater treatment [1], mineral beneficiation [2], micro-oxygenation of wine [3], fermentation [4], ink removal [5], plastic recycling [6] etc. Flotation techniques are used for the various chemical, mineral and biological industries.In this technique, components like fine particles, oil droplets, …
Dissolved air flotation (DAF) is a unit operation capable of removing solid or liquid contaminant particles present in a liquid phase. At the beginning of its use (the early 1900s), DAF was widely used in the ore processing industry as a method of separating mineral ores (Edzwald 1995).Sixty years later, water and wastewater treatment plants began applying DAF to remove …
Separation of particles by flotation adheres to the same laws as sedimentation but in a "reverse field of force." The governing equation in air flotation separation, as in all gravity-controlled processes, is Stoke's Law (at least in laminar flow), which is used to compute the rise rate of bubble flocs, agglomerates, and bubble-oil aggregation (2, 11):

In this study induced air flotation (IAF) through Perspex glass column (ID 10cm and 150 cm heights) has been studied experimentally to treat the oily wastewater of Iraqi North Oil Company. The column operated in a semi-batch mode (batch wastewater, continuous air injection). Different samples of oily wastewater (30,100,800ppm) were used. Air introduced at …
Flotation is commonly referred as the counterpart to sedimentation. The principle of flotation lies in attaching the suspended particles to air bubbles, thus driving them to the surface of the water against gravity for subsequent removal (Palaniandy et al. 2017; Kyzas and Matis 2018).For this, the suspended particles are subjected to a coagulation and flocculation …

Using the "shallow layer theory" and "zero speed" principle, through careful design, it integrates agglomeration, air flotation, slag skimming, sedimentation, and mud scraping. It is a high-efficiency equipment for water purification treatment. Superficial DAF in paper mill is designed according to Zero Speed Principle and Shallow Pool Theory.
