An amalgam separation and collection apparatus for the collecting and separation of amalgam in a dental vacuum waste stream. The apparatus has four primary chambers. The separation chamber is the connection point for th e incoming waste flow and once the waste flow has entered the apparatus, the separation chamber allows the division of waste stream into vacuum air and water particle amalgam. The vacuum air is permitted to flow through the unit via vacuum exhaust tube and is unobstructed. The water/amalgam mixture is deposited from the separation chamber into the sedimentation chamber. Separation by sedimentation occurs in this chamber causing the larger amalg am particles to settle to the container base while the cleaner water raises and water falls under gravity into the filtration chamber. The wastewater with trace amalgam passes through a heavy metal removal bed in the filtration chamber. The purified amalgam free water collects in water re-entrainment chambe r located of the base of the filtration chamber. The collected water is introduced to the vacuum air via an orifice in the vacuum exhaust tubing. A tube is connected to dental office vacuum pump permitting function. The amalgam waste is retained in two removable chambers namely the sedimentation and filtration chambers.
