<p>Known sedimentation tanks for separating off settling materials utilise, in addition to gravity, also other forces, especially centrifugal forces. The tank, divided by a lead pipe into an outer sedimentation zone with downward flow and an inner sedimentation zone located in the interior of the lead pipe, has parallel-plate separators as a post-purification zone. According to the invention, the feed flow is tangential and the lead pipe tapers conically downwards. In the lower section of the lead pipe, a suspended bed thus forms in which particles suitable for settling agglomerate. <IMAGE></p> |
