Aviation – Glycol Recovery

Aviation – glycol recovery from spent aircraft deicing fluid to treatment of tanker cleanout water are services provided by Dynatec.

The deicing fluid is typically formulated from either propylene or ethylene glycol and water with additives. The waste stream contains high levels of COD and BOD.  

Historically, the only on site option for treatment has been large biological treatment systems.  Dynatec’s innovative treatment process uses membrane filtration without biologically treating the wastewater with far less space.  Additionally, glycol is recovered from the process.

Contaminants Removed

Dynatec has provided comprehensive integrated systems to produce purified water that can be safely discharged to sewer without surcharges. Further, the system produces a concentrate of glycol that is sold to others or re-blended as deicing fluid. The system provides the airport with many benefits including:

  • High-quality purified water to meet stringent authority discharge limits
  • Elimination of treatment chemicals
  • High concentration of glycol in the concentrated waste for use in other applications or for re-blending new deicing fluid
  • Ability to treat a constantly changing waste concentration without process upsets
  • Minimal operator attention required
  • Low operating and maintenance cost

Dynatec has several systems operating, processing forty to seventy thousand gallons per day at glycol concentrations varying from one half of one percent to three percent (0.5% – 3%). The systems consistently produce water with COD less than 200 ppm. The systems concentrate glycol up to twenty percent. A secondary evaporator system produces a concentrate greater than ninety percent glycol.

Dynatec can provide the system as a capital project, or on a Contract Service basis whereby Dynatec designs and builds a complete system that is owned, operated and maintained by Dynatec (DBOOM). The charge for Contract Service is volume based, incurring no capital or other expenses for the airport.
