<p>The invention relates to a method for separating sludge in a clarification basin, characterized in that the sludge (7) is collected in said clarification basin (2); the sludge is circulated in a stream that has a vertical component using first, static, flow guide means (10), the sludge is recirculated on itself during sedimentation so as to increase the floc size and allow the latter to precipitate more rapidly than in natural sedimentation; the sludge is recirculated in a centripetal flow using second, static, sludge guide means (22) to bring the sludge back toward the centre of the clarifier. The sludge is withdrawn from the clarifier (8). The invention relates to a device (20) for implementing this method, designed so that it can be fitted to a clarifier.</p> |
