Our LAR™ QuickTOCairport™ TOC COD 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 QuickTOCultra TOC water analyzer. The QuickTOCultra 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.
The results of the TOC analysis can be used to determine the effectiveness of the de-icing process and to identify any potential environmental concerns related to the discharge of wastewater containing de-icing agents. If the TOC levels in the wastewater exceed regulatory limits, corrective actions can be taken to reduce the TOC levels, such as implementing alternative de-icing methods or treating the wastewater before discharge.
Here are some airport de-icing and wastewater standards:
The QuickTOCairport TOC COD water analyzer is typically used at airports to monitor the quality of wastewater generated by aircraft and other airport operations. The analyzer can measure the Total Organic Carbon (TOC) and Chemical Oxygen Demand (COD) levels in the wastewater, which are important indicators of the presence of organic contaminants.

Surface water and de-icing wastewater should be continuously monitored at airports for several reasons including:
The use of inert materials as well as a pump, which is installed downstream of the sample stream, prevent carryover and memory effects caused by absorption and adsorption. The automatic ranging feature ensures reliable measurements between 0.1 – 50,000 mg/l C without dilution or pretreatment of samples. This means, fluctuating loads and adhesive samples are easily analyzed.
For an exact TOC measurement all carbons bonds – incl. particles – must be reliably combusted. LAR’s unique robotic system is capable of transporting and measuring a high content of solid matter without any filtration of the sample. Additionally, our ultra-high temperature method with combustion at 1,200°C guarantees the complete oxidation of the sample. This analysis results in TRUE TOC.
