A system (1) for continuously clarifying liquids having solid suspended substances by means of flotation with dissolved gas substantially comprises a flotation basin (2), a rotary scroll (5) on the top of the basin, in which system (1) the clarified material means comprise a perforated toroidal element (30) spaced from the bottom of the basin (2) at a distance from 1/10 to 5/6 of the height of the liquid in the basin or by perforated pillars, and arranged at a middle distance with respect to the outer diameter of the basin and/or the supplying of the pressurized material being performed partially in a direct manner and partially in an indirect manner with a mixing chamber (7) and by supplying them to said basin eccentrically with respect to the middle vertical axis (A) of the basin, and/or the flotated material removing scroll having a simplified construction, thereby improving the removal or stripping yield of the suspended solid substances and enhancing the flotated layer outlet speed. |
