Abstract
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.
