  • Sludge treatment − dissolved air flotation. | Sludge ...

     · Dissolved air flotation (DAF) provides thickening of sludges ( thickens the sludge) by encouraging the solids to float to the surface, rather than allowing them to sink as in gravity thickening. DAF is applied to increase the sludge solids concentration when these solids are neutrally buoyant ( neither sink nor float) and so cannot be readily removed by settling.

  • Dissolved Air Flotation | Best DAF Wastewater Treatment ...

    Dissolved air flotation systems (DAF) are a wastewater treatment process that floats and flocculates particles in wastewater to removes suspended matter like oil or solids. It works by dissolving air in the water 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 waste matter causing it ...
