  • Patent number: 5472176
    Abstract: A silver recovery device for recovering silver from photographic fluid is provided. The silver recovery device includes an outside container having a fluid inlet and a fluid outlet. The fluid inlet has an extension tube which causes the entering fluid to fall upon a silver recovery cartridge. The silver recovery cartridge generally includes compressed steel wool surrounded by an outside liner. The steel wool reacts with the silver contained within the photographic fluid. The silver recovery cartridge can also include baffle plates for further dispersing the fluid as it filters through the steel wool. The silver recovery cartridge is supported within the outside container by a support grid. The support grid allows fluid to filter through the cartridge and then flow out the fluid outlet.
