The use of the Mead Ferricyanide Solution Management System, for batch mode regeneration of all spent ME-4 ferricyanide bleach used at the Aerospace Audio Visual Service, Norton Air Force Base, CA was investigated. Installation of the system was modified to process the effluents from multiple processors in order to increase the cost benefit of the system. Problems associated with maintaining proper bleach feed pressures and replenisher flow were encountered. Results indicated that the system did regenerate ferricyanide bleach to standards required for photoprocessing. Chemical costs using the electrolytic process were less than one half that previously associated with persulfate regeneration.
