Apparatus and method for removing amalgam and waste particles from dental office suction effluent
An apparatus and method for removing amalgam and waste particles from dental office suction effluent. The apparatus includes an upper chamber and a solids collection canister removably secured thereto. Dental office suction effluent drawn through a dental suction wand enters the upper chamber along a lateral flow path above a substantially cylindrical internal wall portion. A gas component of dental office suction effluent changes direction by more than 60° before it exits the upper chamber through an exit port. A riser conveys a liquid and solids component of dental office suction effluent through a drain into the solids collection canister. A flow restrictor allows liquids and gases to exit the solids collection canister interior volume but prohibits solids from exiting the solids collection canister interior volume.
1. A solids collection canister that is capable of being removably secured to a dental amalgam separation apparatus for collecting amalgam from dental effluent, said dental effluent originating from at least one dental suction wand, the solids collection canister comprising a top portion and a bottom portion which together form an interior volume;
the top portion is provided with a first opening and a second opening; said first opening communicates with a drain in order to receive dental effluent containing liquids and solids from the dental amalgam separation apparatus; said first opening further being in communication with a riser that conveys said dental effluent containing liquids and solids originating from said at least one dental suction wand drain through said first opening to the bottom portion of the solids collection container, whereupon solids in the dental effluent will settle and accumulate in the bottom portion of the solids collection canister; the second opening communicates with a flow restrictor disposed in the solids collection canister interior volume, said flow restrictor being adapted to allow liquid and gases in the dental effluent to exit the solids collection container, but to prohibit solids of the dental office effluent from exiting the solids collection container interior volume.
2. The solids collection canister of claim 1 , wherein the solids collection canister is defined by a flange located on the top portion of the solids collection canister.
3. The solids collection canister of claim 2 , wherein the flange is capable of removably securing said solids collection canister to a dental amalgam separation apparatus.
