Propylene Glycol Disposal

Propylene Glycol Disposal

(OP)
Hello.  I have a client (a fairly small airport) that has a problem with disposing of the propylene glycol collected from the aprons during deicing operations.  Currently, trench drains located on the aprons collect all of the runoff from the aprons.  During deicing operations, valves in these trench drains are opened and the aircraft deicing fluid is diverted to a collection basin.  The original design provided that collected solution was metered into the local sanitary sewer.  However, certain political issues led to the waste treatment plant being unwilling to accept the wastewater.  

Currently, the airport tests the collected water periodically and pumps it into a local creek when it meets the required NPDES permitted conditions. We are in the process of looking into a variety of other disposal options (aeration, biofiltration, etc.).  Since the airport is so small, the propylene glycol solution is way too diluted to consider recycling as an economically viable option. Does anyone have any suggestions?

Thanks
