    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.

    The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.

  • Dissolved Air Flotation Process in Wastewater Treatment

    Dissolved air flotation (DAF) is a water treatment process designed to remove oils, solids, and greases. In fact, the process helps clarify wastewaters – and other waters – by eliminating different types of suspended matter. The DAF process dissolves air in the water under pressure – then releases it at atmospheric pressure. The dissolved air flotation process takes place in a tank basin ...

  • Wastewater treatment by flotation - SciELO

    The flotation process, when applied in wastewater treatment, use methods of air injection in such a way that small air bubbles (<0.1mm) should be formed. This is necessary due to the small size, low density and usually hydrophilic properties of the solids to be removed. These factors when combined make the removal of the solids in solution a difficult or even impossible task [Richter, 1976 ...

  • DAF - Dissolved Air Flotation Wastewater Treatment

    DAF or Dissolved Air Flotation is a simple but ingenious concept. Make tiny bubbles by dissolving gas (air typically) into water under pressure according to Henrys Law of gas whereby the pressure applied to gas will dissolve it into liquid (water). A can of soda demonstrates this nicely in a batch format. When you pop the top on a can of soda you are releasing the pressure and the gas (CO2) is ...
