Comparison of LBOD, DE-1006A, & Conventional Propylene Glycol-Based Aircraft Deicing Fluids in Terms of Potential Environmental Benefits

Abstract : This document presents a comparative evaluation of aircraft deicing fluids (ADFs) developed and field tested under ESTCP to a conventional propylene glycol (PG) based ADF. The two new Type I fluids are LBOD, developed by Foster-Miller, Inc. (FMI), and D3-1006A, developed by Battelle. The conventional ADF used in this comparison is Octaflo EF, a PG-based Type I product used by the U.S. Air Force. The LBOD and D3 fluids were designed and formulated to have a lower five-day biochemical oxygen demand (BOD5), thus decreasing the rate of oxygen depletion in receiving water systems as degradation of the fluid occurs. They were intended to serve as drop-in replacements for conventional Type I ADF products and were field tested at the Niagara Falls Air Reserve Station (NFARS) in February 2006. The comparisons presented in this document were conducted to memorialize the degradation rate studies conducted on the fluids as part of this project and to serve as a basis for evaluating products that may be developed in the future.
