Minimization of Chromium-Contaminated Wastewater at a Plating Facility in the Eastern United States.

摘要

Because construction of a new plating facility is currently planned, a complete renovation of the existing plating facility is not economically feasible. As a result, the program sponsor, the Naval Energy and Environment Support Activity (NEESA), was given the task of demonstrating the use of innovative wastewater treatment technologies that will minimize the hazardous wastes generated at the facility and maintain compliance with the local discharge limits until the new facility is constructed. This paper will discuss (1) the plating facility modifications which resulted in an 85% reduction of the quantity of chromium contamination exiting the plating facility, (2) the results of the RO pilot-scale tests, and (3) start-up of the full-scale RO/evaporator system at the plating facility. 1 ref., 8 figs., 3 tabs.
