PROJECT NUMBER: 37867
TITLE: Performance Evaluation Equipment for Electro-Optic and Infrared Imaging Systems
CODE: Canceled
UPDATE SUBMISSION DATE: 1996-04-29
NARRATIVE: The objective is to provide evaluation methods and support equipment for the test and evaluation of Electro-Optical (EO) and Infrared (IR) reconnaissance systems. The equipment will present EO and IR moving targets in the laboratory which simulates real tactical and ground truth objects. It provides for an imagery interpreter. It will evaluate digital and analog image date to provide the necessary figures of merit to insure the reliable performance of new and repaired imaging systems. This equipment will fill a void in imagery evaluation created by an evolution from filmed reconnaissance to newer technology.

PROJECT NUMBER: 9025
TITLE: Plastic Media Blasting (Aircraft Airframes)
NARRATIVE: To meet increasingly tight wastewater discharge standards, aircraft will be stripped using Plastic Media Blasting (PMB) in lieu of chemical stripping (when approved by NAVAIR). Wastewater generated by chemical stripping requires treatment before discharge. Waste products generated by PMB contain chromium, cadmium and blasting grit. PMB process discharge does not require treatment, hence, the disposal cost is significantly lower than that of the chemical stripping process.

PROJECT NUMBER: 9020
TITLE: Plastic Media Paint Removal Booth
NARRATIVE: This booth eliminates the need for hazardous chemical strippers to remove paint from aircraft parts. The system employs equipment similar to conventional sand blasting units to propel small plastic pellets at the aircraft's surface. The plastic pellets rapidly remove paint from the surface while doing no damage to the underlying substrate. Cost savings with this system are tremendous due to the reduced depainting time and hazardous waste treatment cost avoidance.

PROJECT NUMBER: 57545
TITLE: PMB Paint Waste Biodegradation
NARRATIVE: This project would develop cultures to biodegrade mixed PMB-paint wastes, for pre-pilot plant incorporation. In Task I of this proposed study, representative PMB and PMB-paint waste samples will be obtained from Hill Air Force Base (HAFB) and/or Kelly Air Force Base (KAFB) and characterized. TRA's PMB and PMB-paint waste degrading microbial system(s) will then be tested. An initial reaction rate will be established for each system and the most promising identified; in Task II, constituent isolation, characterization and/or identification will be performed. Constituent biodegradation reactions rates will also be established. Tests will determine if pure or mixed cultures are required to degrade the PMB and PMB-paint wastes; in Task III, temperature, pH, aeration, pigmentation and particle size will then be evaluated as a function of each degradation activity. Successful cultures will then be ranked; in Task IV, biodegradation will be optimized and final reaction rates established. Environmentally safe biodeterioration will be assured; in Task V, data for necessary design pre-pilot plant parameters will be identified and quantified. An engineering report will be produced.
FUNDING SOURCE/COST: SA/ALC, 625K
STATUS: Canceled.
| Nov 92 | Samples were removed from two sequential bioreactors that were actively degrading paint waste (300 micron) previously acquired from KAFB. These samples were plated on TGY agar plates and incubated at 30 degrees C and 37 degrees C. Daily analysis over a period of several weeks revealed the presence of 5 different microorganisms, 3 of which appeared within 2 days while the other 3 appeared at day 3 & 4. It is believed that these last two organisms do not contribute to the biodegradation; the majority of the analysis will therefore be done with the first 3. Upon isolation, a series of tests were completed to identify each organism. |
| Jan 93 | Further experiments allowed TRA to identify 2 of the 3 primary organisms to the species level: Bacillus cereus, Pseudomas pictorum, Pseudomonas sp. In addition, the paint-waste material (<300 micron previously acquired from KAFB) have been studied for characterization and development of an assay. These tests involved extraction, separation and analysis via thin layer chromatography (TLC) and gas chromatography (GC). |
| Feb 93 | Establishing Initial Reaction Rates in TRA's Biodegrading Cultures. Identifying most promising PMB and PMB Paint Waste Biodegradation System(s). Acquire two new samples from KAFB: one line and one coarse ground. Evaluate each PMB and PMB-Paint Waste Biodegradation Reaction Rate as a function of temperature, ph, aeration, pigmentation, and particle size. Prioritize each culture for further study. Optimize Biodegradation Batch Rates for rapid and efficient PMB and PMB-paint degradation. Establish Final Reaction Rates. Assure environmentally safe biodeterioration. Quantify Data for Design and Construction of Pre-Pilot Plant. Produce an Engineering Report with Installation and Operating Costs Estimates in a Defined Flowsheet. |
| Aug 93 | A final report is in progress. |
| Feb 94 | This project is considered closed by the Air Force. The TRA Technical Report of November 1993 has been distributed by AFMC. |
