摘要： The invention relates to a method and device for processing an exposed color reversal photographic film. This method enables the water consumption of the washing baths to be limited, the water levels being maintained by a counter-current coming from the bath placed downstream, an equivalent volume of water being discharged through an overflow. The wash waters are recovered and treated by a nanofiltration unit capable of giving a permeate which can be recycled to the washing baths. This method makes it possible to overcome the problem of the presence of tin (II) in the first washing bath supplied with water by a counter-current coming from the reversal bath. This process also makes it possible to overcome the problems of discharges of chemical substances to the drains while maintaining a good sensitometry of the developed films.
