    • 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.
    • 本发明涉及一种用于处理曝光的彩色反转摄影胶片的方法和装置。 该方法能够限制洗涤水的用水量,通过来自位于下游的浴的逆流保持水位,等量的水通过溢流排出。 洗涤水被回收并通过能够产生可以再循环到洗涤浴中的渗透物的纳滤单元进行处理。 该方法可以克服在来自反转槽的逆流中在供给水的第一洗涤槽中存在锡(II)的问题。 该方法也可以克服将化学物质排放到排水管上的问题,同时保持对显影膜的良好的感光度。

    • The invention relates to a low-water-consumption method for processing an exposed color reversal photographic film. This method comprises the circulation of this exposed film in: i) a black and white development bath, ii) a first washing bath, iii) a reversal bath comprising at least a buffer agent liable to pass through a nanofiltration membrane and, in addition, the collection of waters leaving the said reversal bath, the circulation of these waters through a nanofiltration device to produce a permeate that is recycled in the said first washing bath, a water volume at least equivalent to that supplied by the said permeate being rejected via the overflow and the said buffer agent being chosen so as to keep the pH in the first washing bath between 5 and 7.

    • The invention relates to a method for processing an exposed color reversal photographic film. This method comprises the step of circulating the exposed film in a fixing bath, in and then a final washing zone comprises at least one washing bath. Each washing bath of this zone comprising a buffer prepared from a weak acid and its conjugated base, with a conjugated base concentration more than 1 g/l, said buffer being chosen to maintain the pH between 4.5 and 6. The method comprises then the step of collecting the contents of the washing baths of this zone and the passage of said contents through a nanofiltration device comprising a membrane, whose cut-off threshold is more than the molar mass of the weak acid and the conjugated base making up the buffer, to give a permeate that is recycled in the final washing zone.
