Dissolved Air Flotation Used In Wastewater Treatment

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.

Dissolved Air Flotation • BiogasWorld

Dissolved Air Flotation (DAF) is a technology used extensively for wastewater treatment in food plants, oil & gas, mining, pulp & paper, many major industries and municipal wastewater plants. It also has a very good fit for its use in clarification of drinking water treatment, especially for difficult to flocculate, low temperature, coloured waters, and waters subject to algae blooms.

Dissolved Air Flotation Process in Wastewater Treatment

13-2-2018· Dissolved air flotation (DAF) is a water treatment process for removing oils, solids, and greases from a water supply. The process helps clarify wastewaters by eliminating different types of suspended matter. DAF dissolves air in pressurized water – then releases it at atmospheric pressure.
