Parameters have been established for effective removal of low concentrations of silver and cadmium from photographic processing effluents using a CROVEX silver recovery metallic replacement system. Parameters include: total photographic processing effluents (composed primarily of wash effluent, fixer, and developer), residence time, pumping pressures, and maximum heavy metal input. Techniques using these parameters yield silver and cadmium removal approaching 98%.
