In accordance with our Class A Recycling Permit, all spent fixer must be poured into the fixer trays that have been installed in all darkrooms. The liquid flows through a bucket that is equipped with a steel wool cartridge that filters out the silver before the remaining liquid is released to the sewer.
The fixer units drain slowly and we ask for your patience in this matter. In order to effectively collect the silver in the cartridge, the flow of the liquid must be restricted.
The five gallon buckets that filter the fixer are serviced each summer. The buckets are replaced and the cartridges are sent out for recycling
Please contact the Office of Safety & Environmental Compliance if you are experiencing any problems with your setup.
