ENVIRONMENTAL PROJECTS
Description (continued):
compounds (VOC) emissions (Aerospace National Emissions Standards for Hazardous Air Pollutants (NESHAPs)), and require no solvent use
(Total Release Inventory (TRI)) either for mixing nor paint gun cleaning.
c. Ion Vapor Deposition Sputtered Aluminum System, Hill AFB, UT: The external surfaces of landing gear are presently coated with
aluminum using the Ion Vapor Deposition process. This has proven to be a great improvement over the previous cadmium plating process by
reducing the generation of hazardous waste, the generation of industrial wastewater, and the exposure of workers to highly toxic cadmium.
Internal surfaces of the landing gear, however, must still be cadmium plated because conventional Ion Vapor Deposition technology is not
capable of putting a coating on internal diameters. The purchase of an Ion Vapor Deposition Sputtered Aluminum System will enable the Hill
AFB to put the same aluminum coating on both the external and internal surfaces of the landing gear. This equipment will further reduce the
generation of hazardous waste and wastewater and greatly improve working conditions.
FY02:
d. Industrial Wastewater Pretreatment, Tinker AFB, OK: FY02 funds will procure equipment to pretreat the concentrated wastewater from the
aircraft maintenance area. By pre treating the concentrated wastewater, the loading on the Industrial Wastewater Treatment Plant (IWTP) will
be more dilute, resulting in reduced chemical usage per gallon and a reduction in the generation of hazardous sludge.
e. A-LIX Treatment System, Robins AFB, GA: FY02 funds will purchase Anion Liquid Ion Exchange (A-LIX) equipment to remove
chromium from the chrome plating line wastewater, without generating a sludge. The end product is a concentrate chrome solution that
can be reused in the plating shop or sold back to the vendor.
f. Ultrahigh Pressure Water Jet Stripping of Thermal Sprayed Coatings, Tinker AFB, OK: This project will purchase an ultra-high pressure
water jet spray system to physically remove thermal-sprayed metallic coatings. The part is mounted on a turntable where a robotic arm directs
the nozzle to spray the part with the highly pressurized water in a preprogrammed path. This system will reduce the amount of hazardous waste
generated from the present chemical or grit blasting processes, by allowing for the filtering of the removed coating from the water.
