Silver recovery device
 Silver is recovered from the rinse water from a photographic film processing unit by means of a silver recovery device in which the rinse water is passed through at least one bed of ion exchange resin particles maintained in fluidized condition by the water flow. A plurality of such beds are preferably connected in series with rinse water being recirculated until fresh rinse water causes overflow to the next bed and finally to a collection vessel. Fluidization is interrupted periodically to create quiescent periods which aid in removal from the resin particles of accumulated gelatin from the processed film.
