ABSTRACT:
The present invention concerns a process for treating photographic baths containing organic contaminants and a device for implementing this method.
The process for treating a photographic bath containing contaminants comprises the step of putting the photographic bath in contact with a photographically inert material, resistant to a high pH and having a lipophilic surface.
This method affords an improvement in the processing of photographic products.
