A method and a system for recycling spent ethylene or propylene glycol recovered from aircraft deicing solutions is described. The recovered spent ethylene or propylene glycol contains water and other undesirable substances which require to be removed to produce a solution free of these substances which can be further processed to remove substantially all of the water content and to blend-in additives required to certify the final glycol solution for aircraft deicing. The method and system employs a computer controller for continuous automatic batch processing of the spent glycol, including, in combination, filtering, distillation, blending and testing in specific sequences and achieves an improved quality recycled glycol of a purity of at least 99.5% and preferably between 99.6% to 99.9% glycol concentration.

A deicing fluid recovery system includes a vehicle movable adjacent to an aircraft and including a holding tank configured to store deicing fluid and a receptacle configured to capture deicing fluid from the aircraft during a deicing procedure. During the deicing procedure, deicing fluid runoff from a surface of the aircraft may be captured into the receptacle and transferred from the receptacle into the holding tank. The deicing fluid runoff may be captured into the receptacle before the deicing fluid runoff contacts ground.

An aircraft de-icing system has a nozzle with at least one movable element configured to move between a first position and a second position to change a spraying configuration of the nozzle between a first configuration and a second configuration. The aircraft de-icing system further has at least one storage reservoir configured for containing a de-icing agent and a pump for pumping the de-icing agent from the at least one storage reservoir to the nozzle. The aircraft de-icing system further has a pressurized air source in fluid communication with the nozzle for delivering pressurized air to the nozzle. The nozzle is configured for selectively mixing varying amounts of the pressurized air and varying amounts of the de-icing agent to provide a spray pattern for application on a surface of an aircraft based on a position of the at least one movable element between the first position and the second position.
