PIGNAT Water Treatment by Dissolved Air Flotation – TFA3000



Implementation of water treatment by dissolved air flotation

  • Clean method minimizing the use of chemicals

Dissolved air flottation

  • This unit allows the user to perform a water treatment by flotation tanks to dissolved air developed. It is carried out in 4 steps:
    •  Bubbles generated for dissolved air.
    •  Bubble adhesion to particles in order to form solid-air particles.
    • Formation of an air/solid particle conglomerate and flotation of the formed conglomerate.
    • Separation of the floating emulsion

Separation of suspended particles:

  • Agglomeration by using air bubbles dissolved

Optimization of the process:

  • Combination with chemical treatment (flocculation)
  • Feasibility study on different waters

Study of the influence to flow rate and residence time
