Vehicle galley drainage systems and methods

Abstract:

A drainage system for a galley of a vehicle includes a sink that is configured to receive a colored liquid. A liquid pigment remover is in fluid communication with the sink. The liquid pigment remover is configured to remove color from the liquid. A drain is in fluid communication with the liquid coloration. The drain is configured to pass the liquid overboard from the vehicle after the color is removed (or partially removed) from the liquid by the liquid pigment remover. The drainage system may also include a strainer that is configured to strain particulates from the liquid before the liquid passes overboard out of the vehicle.
