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
