Our LAR™ QuickTOCairport™ TRUE TOC® water analyzer is the ultimate online measuring system for the determination of Total Organic Carbon (TOC) and Chemical Oxygen Demand (COD) for required airport applications.  

Airplanes, runways and landing strips are de-iced with the help of de-icing agents. De-icing agents used in airports are typically formulated with a combination of chemicals, such as ethylene glycol and propylene glycol, to melt ice and snow from aircraft surfaces. These chemicals can be harmful to the environment and can contribute to the Total Organic Carbon (TOC) levels in the wastewater generated from airports during the de-icing process. As a result, it is important to monitor the levels of TOC in wastewater to ensure that the discharge meets environmental regulations.

One way to monitor TOC in de-icing agents is to use a specialized water analyzer, such our QuickTOCairport TRUE TOC® water analyzer. The QuickTOCairport TRUE TOC® water analyzer uses a combustion method to oxidize the organic compounds in the sample and measures the resulting CO₂ concentration to determine the TOC concentration.

To monitor TOC in de-icing agents, a representative sample of the wastewater generated from the de-icing process is collected and prepared for analysis using the appropriate sample preparation techniques, such as filtration and dilution. The prepared sample is then introduced into the analyzer for TOC measurement.

Here are some airport de-icing and wastewater standards:

• Airport Deicing Effluent (40 CFR Part 449) Guidelines | US EPA 
• Airport Deicing Effluent Guidelines Documents | US EPA 
• EU Regulation 528/2012
• EU Regulation 2005/33/EC
• ICAO Annex 14, Volume 1
• IATA Guidance Material and Best Practices for Aircraft Ground Deicing/Anti-Icing
