Abstract:

This report describes the Metals Recovery from Industrial Sludges Program. The program objective is to identify or develop processes for reclaiming metals from a mixed, metal-bearing, waste sludge produced by the Industrial Waste Treatment Plant at Tinker Air Force Base. A Literature review, market survey, and preliminary laboratory tests have been completed. Metal separations appear promising through selective chemical precipitation processes. Other technologies including electrowinning, electrodialysis, and wet air oxidation may be combined with chemical precipitation to offer a feasible recovery process. A building was constructed around the Tinker AFB demonstration IWTP system in order to offer climatic protection to the other Air Force projects currently being performed at this site. Phase II of the program, currently under way, consists of bench-scale testing of identified unit processes and a continued search for alternative methods. At the end of Phase II an overall metals recovery scheme will have been identified and subjected to bench-scale testing and a data base generated for the design of a pilot field verification unit. Phase III of the metals recovery program will consist of design. construction, and operation and evaluation of the pilot field verification unit.
