Stone ME, Cohen ME, Berry DL, Ragain Jr JC. Design and evaluation of a filter-based chairside amalgam separation system. Science of the Total Environment. 2008 Jun 15;396(1):28-33.
This study evaluated the ability of a chairside filtration system to remove particulate-based mercury (Hg) from dental-unit wastewater. Prototypes of the chairside filtration system were designed and fabricated using reusable filter chambers with disposable filter elements. The system was installed in five dental operatories utilizing filter elements with nominal pore sizes of 50μm, 15μm, 1μm, 0.5μm, or with no system installed (control).
