Abstract
A settling apparatus for the separation of amalgam from waste water in a dental procedure includes an inclined passage through which the water is caused to flow from below and upwards while depositing amalgam. The inclined passage has an inclination of between 3.degree. and 15.degree.. It is filled with a large number of thin-walled, narrow tubes, which contact each other in a side-by-side manner. The water flows from below and upwards through the tubes and through the channels between the tubes while amalgam is settled and deposited on the interior, as well as on the exterior, surfaces of the tubes.
