    • In a method for processing silver halide photosensitive materials comprising developing an exposed silver halide photosensitive material, fixing the developed material and washing it with a washing water, the amount of calcium and magnesium compounds present in the replenishing washing water is reduced to not more than 5 mg/l on the basis of the weight of elemental calcium or magnesium and washing water is replenished in an amount of 1 to 50 times the volume of liquid carried over by the photosensitive material from a bath preceding the washing bath per unit area thereof or that the replenishing washing water is introduced into a washing bath after reducing the amount of calcium and magnesium compounds to the range mentioned above and sterilizing the same. The method makes it possible to substantially reduce the amount of washing water while reliably suppressing turbidity and proliferation of microorganisms in the washing water during and after completion of processing.
    • 在用于处理卤化银感光材料的方法中,包括显影曝光的卤化银感光材料,固定显影的材料并用洗涤水洗涤,补充洗涤水中存在的钙和镁化合物的量减少到不超过5 基于元素钙或镁的重量mg / l,洗涤水的补充量是由感光材料从洗涤浴每单位面积之前的浴中携带的液体的体积的1至50倍,或补充 在将钙和镁化合物的量减少至上述范围并对其进行消毒之后,将补充的洗涤水引入洗涤浴中。 该方法可以在可靠地抑制洗涤水中和处理完成后的洗涤水中的微生物的浊度和增殖的同时大幅减少洗涤水量。
