Aircraft deicing reduces the aircraft weight and prevent unfavorable aerodynamics, which is reflected in a price reduction and ensures high standards of quality and safety. At special deicing areas of the airfield, the ADL (aircraft deicing liquid) is sprayed on the aircraft. ADL is a mixture of propylene glycol or ethylene glycol with water and is used at temperatures up to below -25°C. The deicing liquid is made from a mixture of water and ethylene glycol or propylene glycol in a ratio of 50 - 80 wt% glycol. The desired concentration of the mixture is controlled on site. The measuring system LiquiSonic® provides a precise inline concentration measurement of the deicing liquid, whereby the target concentration can be exactly adjusted. For a better surface adhesion on the aircraft, the deicing liquid is additionally mixed with thickeners. Thereby, the deicing liquid works as a protection against refreezing. Depending on the type of aircraft and the weather conditions, different types and concentrations of ADL are used. During the deicing process, the deicing liquid is mixed with surface water and snow. The diluted ADL is directed in underground channels and stored in collection tanks. The concentration of the collection tank is inline monitored. Depending on the residual concentration, a deicing liquid recycling (>1%) or discharge into the waste water system is initiated. By use of LiquiSonic® inline concentration analyzers, the residual concentration of the deicing liquid is determined and further processing steps (distillation or waste water treatment) can be controlled.

Aircraft Deicing Customer value LiquiSonic® analyzer provide precise inline ADL concentration control with real-time monitoring. The LiquiSonic® sensor is installed in the transport piplines (e.g. DN 50), collecting lines or reservoirs. Particularly in the reservoirs, sensors with a length up to 4 m can be installed. LiquiSonic® reduce expensive total organic carbon (TOC) lab measurements: · time saving: 1 h per day · cost per hour: 50 € (60 $) · total cost savings: 10.000 € (12,000 $) per year The continuous monitoring of the deicing liquid in the waste water ensures compliance with...
