Aviation - Aqueous Film Forming Foams (AFFF)
RAAF Amberley, Queensland, Australia
AdTech has successfully treated AFFF wastewater to re-use quality for RAAF Amberley, RAAF Williamtown, Army Aviation Centre, Oakey, Queensland and Air Services Australia. Wastewater generated by fire training and vehicle service tests at RAAF Amberley in south-eastern Queensland is captured and stored on the Base in a large underground storage tank. This wastewater typically contains hydrocarbons and various surfactants form the Aqueous Film Forming Foam (AFFF) used in aviation fires.
A number of these surfactants have been shown to be non-biodegradable and can bio- accumulate. For this reason, waste was previously taken off-site for disposal. AdTech’s proprietary filtration/adsorption media has been shown to remove these surfactants from solution. Test results from full-scale trials show greater than a 99.8% reduction and the water deemed suitable for re-use.
After approval from Defence Environmental personnel, AdTech began regular treatment of Amberley’s AFFF waste in 2007. We set up a two-stage filtration adsorption plant using transportable equipment and now treat approximately 40,000 litres each month during two one-day service visits. Treated water is stored in a dedicated 50kl holding tank and is re-used in fire training operations.
This on-site treatment saves Defence as much as $50,000 p.a. when compared to off-site disposal.
