Dissolved Air Flotation - an overview ScienceDirect Topics

Dissolved air is the most common type of flotation gas used in potable water treatment. The dissolved air flotation (DAF) process mixes a clarified stream from the outlet of the unit with air at 3–9 bar, to produce a supersaturated (compared with saturation at atmospheric pressure) solution of air in water.

Dissolved air flotation - Wikipedia

Dissolved air flotation (DAF) 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 dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.

ABSTRACT Microalgae biomass has great potential for being used as feedstock for the sustainable production of biodiesel, as it is able to produce 7–31 times more oil than the top terrestrial crop. It is a green alternative to the currently utilized energy sources as it can reduce CO, CO2 and hydrocarbon emissions. However, downstream processing costs for the dilute biomass are a major challenge.

versely, in mineral flotation or dispersed air flotation systems, about 10 m3 of air are dispersed into 1 m3 of water (pulp) or 500 times more than that used in DAF. Thus, DAF microbubbles are used to capture only the small, light solids and metal-ion hydroxide flocs, bacteria, etc., having specific weights close to that of water.

Hydrodynamic aspects of flotation separation

Jan 01, 2016  In Denver type dispersed-air flotation tanks turbulence is dominant due to the intense mixing imposed by an impeller, so gravitational/buoyant effects can be ignored. In a properly operating flotation tank no settling particles occur in both zones. Ill-functioning may occur if a tank is operated using bubbles larger than it was designed for .
