Silver Recovery in Dark Rooms
The silver recovery inspection program ensures that no silver is discharged down the drain. Recovering silver from waste water solutions such as those produced by film processing units and medical x-ray films requires compliance with the EPA regulations, holding environmental accountability for those producing silver discharge. The EPA has standards for the disposal of silver in concentrations exceeding 5 ppm (parts per million). It is Emory University’s policy that zero silver is discharged down the drain to ensure this limit is not met or exceeded.
Spaces containing film processing units are inspected annually, at a minimum, to ensure the standards are met. Please email firstname.lastname@example.org for further information about installing and decommissioning dark rooms.
