<p>The invention relates to a method for clarification by flotation of water loaded with material in suspension, characterised in that the clarification treatment is carried out in two successive stages in a single plant. The method comprises a static flocculation step with descending current, integrated with a primary separation step for the heaviest particles, the zone in which the primary separation of the heaviest particles occurs being situated beneath the zone in which the static flocculation step is carried out and comprises a removal of the heaviest particles and a flotation step which guarantees the removal of the light particles, the decantation speed of which is below the threshold for cleaving the flotation agent.</p> |
