Claim 6:
7. A deicing-liquid recovery unit comprising:
a rotatable brush; and
a collection tray fluidly connectable to said collection tank and located in front of said rotatable brush in a first direction,
wherein the rotatable brush is arranged to sweep an apron/deicing platform surface such that deicing liquid and snow resting on the apron/deicing platform surface is forced into the collection tray,
said collection tray having an external bottom side, said external bottom side arranged at a distance of 3 to 100 cm from the apron/deicing platform surface such that said collection tray passes over said deicing liquid and snow before said rotatable brush sweeps the apron/deicing platform surface when said deicing-liquid recovery unit is moving in the first direction,
wherein no part of the deicing-liquid recovery unit, other than the rotatable brush, engages the airport apron/deicing platform during movement of the deicing-liquid recovery unit in the first direction,
wherein a first conveyor is arranged in said collection tray and arranged for moving the deicing liquid and snow swept into the collection tray in a direction perpendicular to said first direction and towards an exit port, and
wherein said system further comprises a second conveyor for transporting the deicing liquid and snow from said collection tray to said collection tank.
