Continuous SAC254 And TOC Measurement Of Airport Runoff Streamlines Separation Of Polluted And Unpolluted WatersSource: Hach Company
The pollution of the surface water on airport land is caused by the de-icing of aircraft wings and taxiways with glycols and acetates, and by fuel or oil spillage.
Control of airport runoff waste water containing these contaminants consists of diverting it to a treatment plant as needed, where contaminating agents are completely broken down. An advanced drainage system with suitable pollution loading measurement is a prerequisite for addressing increasingly stringent environmental requirements.
Continuous monitoring of the airport waste stream is key in controlling runoff. Measurements signal the end of pollutant presence, so that only contaminated waste water is fed to the treatment plant and treatment costs are minimized. Monitoring also documents water quality at transfer to the treatment plant or receiving body of water.
