In previous project, jar and dynamic testing showed that the sodium sulfide/ferrous sulfate process was a viable method for reducing hexavalent chromium and removing heavy metals from the Tinker AFB industrial wastewater with significant decrease in sludge production and treatment costs. In this phase, pilot-plant field verification studies were conducted to evaluate the chemical and physical parameters of the chromium reduction process, the precipitation and clarification process, and the activated-sludge system. Sludge production was evaluated and compared to the sulfuric acid/sulfur dioxide/lime process.
