<p>The untreated liquid enters into the settling vessel (7) of a settling device composed of three sections (5, 6, 7) beneath a first inclined clarification device (21) and flows upwards in the opposite direction to the settled particles flowing downwards into a thickening region. Beneath the entry region (20) for the untreated liquid, the particles separated off in the first inclined clarification device (21), which particles pass through this entry region (20) on sinking, are further conducted through a second inclined clarification device (24), before they pass into a collection chamber (25). The settling rates for the particles and the thickening of the resulting sludge are intended to be improved by the novel process. <IMAGE></p> |
