Abstract: A flotation apparatus comprising a treatment chamber provided, at one of its ends, with an inlet for the liquid to be treated circulating without turbulence and, at the other end, an outlet for the treated liquid, an inlet pipe for the treatment water under high compression charged with gas being disposed at the lower part of said treatment chamber. In this apparatus the inlet pipe for the water under high compression is located below and in the neighborhood of the inlet for the liquid to be treated in the treatment chamber, an outlet pipe for the treatment water being disposed at the lower part of the chamber, below and in the neighborhood of the outlet for the treated liquid, means for allowing the passage of the micro-bubbles coming from the water under high compression being furthermore provided to create between the two ends of the chamber two distinct, superimposed and parallel flows, the upper one for the liquid to be treated, the lower one for the water under high compression.
