摘要

This invention relates to a process for the treatment of a seasoned stabilization bath containing at least 2 g/l of thiosulfate carried over from the fixing or bleach-fixing bath wherein said stabilization bath is treated by means of a nanofiltration system to yield a photographically useful permeate.
