The objective of this research was to validate the use of sodium sulfide and ferrous sulfate in reducing hexavalent chromium and removing heavy metals from electroplating, and industrial waste waters. Jar tests, and dynamic tests, were conducted using distilled water, electroplating rinse waters, and industrial waste waters from Tinker AFB Industrial Waste Treatment Plant. Optimum process parameters were evaluated as well as analysis of the effects of typical contaminants and complexing agents, along with the effects of the process on downstream treatment. The information obtained verified that the sulfide-treatment process will meet discharge-permit requirements while reducing chemical and disposal costs. The results were the basis for continuing to Phase II, Pilot-Scale Study on Actual Industrial Waste waters.
