Flotation is largely dependent on differences in surface wettability of valuable species and gangue in an aqueous slurry or pulp (Hanumanth and Williams, 1988).The surfaces of valuable particles are either inherently hydrophobic by natural surfactants or selectively rendered to be hydrophobic by an additive—synthetic surfactant or collector (Yu et al., 2017).

Essential for smoothening of the three-phase flow in the flotation cell is the geometric design of the laminator. The hydraulic laminator consists of a register of concentric funnels (diffusers) with a spherical-cap shaped exit area 4.85 times larger than the total inlet area (Fig. 2).

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewater by the removal of suspended matter such as oil, grease, or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank or basin.

A flotation cell is the primary unit operation used to recover fine oil droplets from produced water systems. Both mechanical induced gas flotation (IGF) and hydraulic dissolved gas flotation (DGF) cells have been used for residual oil removal from produced water since the late 1960's (Sport 1970; Bassett 1971). Mechanical IGF cells were ...

Flotation techniques for removal of finely dispersed contaminants have become widespread in industrial and domestic wastewater treatment. In contrast to gravity separation of dispersed wastewater contaminants, the efficiency of the flotation treatment method is ascertained by the hydraulic size of the formed 'air bubble–contaminant particle' aggregates.
