Abstract : This document reports the results of an economic analysis of advanced and emerging industrial wastewater treatment plant (IWTP) technologies. Conventional IWTPs have been capable of handling a wide range of flow rates and concentration of influent waste streams from metal plating and finishing shops. New regulations and the increase in disposal costs for solid wastes have required the Navy to focus on improving the metal removal efficiency and waste generation rates. The Navy is developing Zero Discharge Technologies for three waste steams: (1) chromium, (2) cyanide, and (3) acid/alkali cleaning wastewaters. A Zero Discharge IWTP conceptual design described in this document incorporates advanced separation technologies for metals removal and recovery, advanced oxidation processes (AOP) for mineralization of organics, and membrane separation technologies. This document reports an economic analysis of the unit processes identified in the Zero Discharge IWTP design, identification of further effluent polishing/purification methods, and an assessment of system costs for each effluent recycling option. jg p3
