Separator Requirements

Amalgam separators remove particles of amalgam from wastewater that passes through your facility's vacuum system, vacuum line filters and screens, and/or chair-side traps, before the wastewater is discharged to a sewer.

  • Amalgam separators must be demonstrated to remove at least 98 percent of the waste amalgam in wastewater. These demonstrations are usually conducted by professional laboratories at the request of the separator manufacturers, using a specific protocol developed by the International Organization for Standardization (ISO protocol 11143).
  • Facilities that participated in the voluntary program are allowed to continue using their 95 percent efficient amalgam separators, as long as the equipment continues to achieve this removal efficiency and is maintained in accordance with manufacturer instructions. When separators need to be replaced, units that meet the 98 percent removal efficiency standard must be installed.
  • The separator must serve all wastewater that contains waste amalgam (including wastewater from chairs and cuspidors), and needs to be sized to accommodate the facility's maximum amalgam wastewater flow.
  • The separator must be installed, operated, and maintained according to the manufacturer's instructions.
  • At least one employee must be familiar with the procedures for operating and maintaining your amalgam separator system. In addition, all staff members who handle waste amalgam must be informed about these procedures.

Cleaning & Disinfecting Vacuum Lines & Drains

  • Use only disinfectants and cleaning agents that are biodegradable, non-corrosive (pH between 6.5 and 9.0) and non-oxidizing in your facility's vacuum lines and all other drains that are connected to amalgam separator equipment.
  • Bleach is not an acceptable disinfectant, since it mobilizes the mercury in the separator and prevents the separator from capturing waste amalgam.
  • Follow manufacturer instructions on appropriate disinfectants, cleaning agents and maintenance procedures.

List of Approved Amalgam Separators

The following amalgam separators have been tested using a protocol established by the International Organization for Standardization (ISO) Protocol 11143 and have been found to remove at least 98 percent of the mercury from wastewater at specified volumes over time.

Please Note: Most amalgam separators are designed for dry vacuum evacuation systems. Evacuation systems that use wet vacuums or cuspidors generate significantly more wastewater than dry vacuum systems and may not be compatible with certain separators. If your office uses a wet vacuum or cuspidor, you should consult with your separator manufacturer and installation contractor or plumber to ensure that your system removes at least 98 percent of the amalgam from your wastewater.
