| 2000 | Invention patented by James D. Tremel, Chenoa J. Jensen, Garland P. Krabbenhoft, Daniel F. Dolan, and Robert A. Meyer on July 12th, 2000. Abstract: Amalgam and other particles of four microns or more in size are removed with at least 95% efficiency from a particle-containing fluid line, preferably connected to a single dental operatory. Desirably a plurality of parallel centrifugal separators have their inlets connected to the fluid line, and gas outlets connected to a dental vacuum pump. The bottom liquid and particle outlet drains to a particle filter. The filtered water can be reintroduced into the gas flow to the vacuum pump, and the collected particles are disposed of in an environmentally sound manner. |
