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.
Claims9
A settling apparatus for removing amalgam from waste water produced in a dental procedure, comprising a housing having upper and lower compartments separated from each other by an inclined partition wall, said upper compartment defining a pre-settling chamber;
- an inclined passage having an inclination to the horizontal of from about 3.degree. to 15.degree.;
- a plurality of tubes extending through said passage and the number thereof being sufficient that substantially all of the tubes contact other tubes in a side-by-side manner and form channels therebetween;
- means for flowing said waste water from said pre-settling chamber to a lowermost end of said passage and from said lowermost end of said passage through said passage, tubes and channels in laminar flow and out of said passage, wherein the inclination of said inclined partition wall is equal to the inclination of said inclined passage, said inclined passage being disposed in the lower compartment and beneath said inclined partition wall, and wherein amalgam in said waste water is settled in said pre-settling chamber and in and among said tubes and channels in said passage during said flowing of the waste water.
