Information : Closed Loop Recycle Systems for Waste Minimization
Naval Aviation Depot (NADEP), Jacksonville has integrated closed-loop water recycle systems into the electroplating and paint stripping operations, and has provisions for another at the aircraft painting and metal finishing operation. These systems, consisting of standard wastewater treatment unit operations, provide a unique system resulting in significant reduction in hazardous waste and water use while ensuring long term environmental compliance.
The former existing wastewater treatment system included both an industrial wastewater treatment plant (IWTP) and domestic wastewater treatment plant (DWTP) in series. Effluent from the IWTP was reprocessed in the domestic wastewater treatment plant before discharge into the St. John's River. Sludge from both the IWTP and DWTP were characterized as hazardous waste. NADEP, Jacksonville, through an environmental initiative, developed and implemented plans for eliminating the wastewater discharge from the hazardous waste producing operations of electroplating, metal treatment and aircraft painting, and aircraft stripping and metal finishing. Closed loop recycle systems that process the rinse waters and return them to the operation were installed. Currently the system for the electroplating shop is in operation.
