Available in PDF, EPUB and Kindle. Book excerpt: ?Pub Inc Airports that operate in cold climates are required by the FAA to de-ice aircraft and runways. The most common method involves the use of glycol-based aircraft de-icing/anti-icing fluids (ADAF). The majority of these fluids contain either propylene or ethylene glycol that act as freezing point depressants, along with additives such as corrosion control inhibitors, surfactants, and wetting agents. Historically, the runoff of spent fluids from aircraft and pavement de-icing/anti-icing operations has been difficult to manage, resulting in significant discharges to surface waters on both a national and global level. Currently, best-practice treatment of airport storm water containing ADAF is geared for glycol-rich wastewaters, with the treatment efficiency being measured by reduction of BOD and nutrient levels in the effluent. The objective of the thesis was to assess whether the traditional parameters (BOD, COD, and pH) most frequently used to monitor the treatment and release of airport stormwater effluent containing de-icing fluids were adequate indicators of the effluent quality. Current literature was used to evaluate the chemistry, environmental fates, persistence in the environment, and toxicity of two classes of compounds, glycols and benzotriazoles. Glycols were shown to be readily degraded in the environment and relatively non-toxic. Benzotriazoles were shown to be resistant to degradation, persistent, and toxic in the environment. The fate of both of these types of compounds was then evaluated in best practice treatment methods for airport stormwater. Glycols were shown to be effectively treated and benzotriazoles were projected to be recalcitrant. The research supports the hypothesis that using BOD, COD, and pH as measures of suitability of return to the environment for treated stormwater containing spent ADAF is inadequate. New additives and more sophisticated ADAFs affect the toxicity of the effluent and require treatment processes that effectively treat all of the constituents of the fluid.

The specification has been revised to note that Type I fluids shall not contribute to the creation of mold (3.1). In addition, a WSET minimum is now required in the thermal stability (3.3.2.2) and hard water stability (3.3.3) tests and a note has been added to 3.3.3 to indicate that additional testing with softer water may be required. A new section 3.5.3.1 has been added to institute maximum final fluid thickness requirements in the high speed ramp and low speed ramp aerodynamic tests.

This book was released on 2005 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: During winter months at Department of Defense (DOD) air bases, large amounts of aircraft deicing and anti-icing fluids (ADF) (primarily propylene glycol, ethylene glycol, and various additives) are used to ensure flight safety during certain adverse weather conditions. Standard practices at both military air bases and private airports are to direct deicing effluent to large stabilization ponds, the sanitary storm sewer, vegetated swales, or directly to the environment. The objective of this project was to demonstrate that SSF constructed treatment wetland (CTW) technology could cost-effectively remove harmful chemicals from deicing waste streams for immediate and long-term compliance with water quality regulations.
