Abstract: In the typical film processing situation the constant addition of the chemical replenishes in liquid form creates an overflow or effluent condition. The disposal of such effluents through sewage facilities wastes costly and potentially reclaimable solutions and adds to water pollution. Chemical mixing, storage and analytical test procedures have been devised whereby a high percentage of most effluents, formerly discarded, are now restored to replenisher condition and reused indefinitely. These procedures are carried out with no loss in image quality and with substantial reduction in both chemical costs and water pollution. Reclamation of the silver content from discarded film is also discussed.
