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 flota
‐ tion of the formed conglomerate. ‐SeparaƟtin of the floaƟtig emulsion.
2 boosters pumps allows the pressurization in the liquid air contactor and generate dissolved air in water.
