TOC & COD ANALYZERS FOR AIRPORT APPLICATIONS

Water Quality Matters Across All Industrial Applications

In 2012, the US EPA established guidelines for airport deicing effluent (40 CFR Part 449). The guidelines require that large airports with more than 10 thousand flights per year located in cold climates must collect at least 60 percent of the deicer runoff. Airports that discharge to U.S. waters must also meet discharge permit requirements for chemical oxygen demand.  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.  In the winter months airplanes, runways and landing strips are de-iced with the help of de-icing agents. Chemicals such as glycol, acetates or formates are used which are additionally mixed with thickening agents in order to improve their adhesion to the surfaces. Finally, the deicers have to stick to the surfaces to prevent the formation of new ice.

We are the leaders in high-temperature TOC, COD, BOD and Toxicity water analysis for maximum reliability, high-performance and fast response.

Our QuickTOCairport monitoring system is flexible, fast and accurate, allowing compliant streams to run off the airfield while re-directing contaminated flows to storage basins for treatment or recycling.  Due to its innovative injection and oxidation technique, the analyzer is optimally suited for the online monitoring of airfield runoff. With no sample pre-treatment or dilution, the analyzer can handle high salt concentrations and is free from any memory effects.

With our application-specific solution, operators are able to perform efficient and effective water management at airports e.g. deicing wastewater or run-off rainwater.   Our water analyzers were designed to fit environmental monitoring, municipal facilities, and industrial manufacturing applications.  Learn more about TOC analysis.

Surface water and de-icing wastewater should be continuously monitored – from an ecological as well as economic point of view. By using reliable online measurement systems high wastewater charges can be avoided.

FLUCTUATING LOADS AND STICKY SUBSTANCES 

In the winter months airplanes, runways and landing strips are de-iced with the help of de-icing agents. Chemicals such as glycol, acetates or formates are used which are additionally mixed with thickening agents in order to improve their adhesion to the surfaces. Finally, the de-icers have to stick to the surfaces to prevent the formation of new ice.  However, on precipitation this leads to contamination of the surface water and within the analyzer, these sticky (adhesive) substances may cause adhesions resulting in memory effects and/ or carry-over effects. The loads that fluctuate strongly depending on precipitation and use of deicers, cannot be detected accurately. Therefore, within the analyzer, the sample should come into contact with the wet parts as little as possible.  The analyzer measurement range has to be wide enough in order to accurately determine the loads which are monitored by use of TOC as parameter. On one hand, the critical values for public discharge are very low and on the other, the analyzer must be able to reliably measure high concentrations of up to 50,000 mg/l C.

THE BUILDING BLOCKS PRINCIPLE FOR A TAILOR-MADE MEASUREMENT INSTRUMENT

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.

EXACT ANALYSIS AT 1200°C

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.
