Airport Deicing Systems
The use of glycol- and acetate-based chemicals during airplane deicing creates a variety of environmental compliance challenges. Deicing operations result in large quantities of contaminated runoff that is extremely variable in both flow and load. NWC engineers have worked with facility managers at a number of airports around the world to solve this problem, including Heathrow Airport in London, and airports in Buffalo, New York and Edmonton, Alberta.
Experience has shown that large fixed-film, attached-growth biological treatment reactors provide the most robust and cost-effective solution for treating deicing runoff. Since no water is exposed during the treatment process, these low-profile systems can usually be built within the airfield perimeter adjacent to runways, solving the problem of land availability. NWC has been instrumental in developing and applying this technology, which combined with our knowledge of airfield operations, allows us to optimize our solutions for airport engineers.
