Abstract
Apparatus for recovering silver from spent photographic solutions comprises a tray with a number of non-reactive filter elements having successively smaller porosity through which the spent solutions can be passed. Each successive filter element prevents silver particles of progressively smaller sizes suspended in the liquid from passig therethrough. The filters are stacked in a horizontal position within the tray and a tray cover sits on top of the tray, the cover having an opening into which the developing solutions can be poured. The tray includes a drainage port which allows liquid passing through the filters to drain out of the tray.
