Abstract
A method and system are described for the treatment of aircraft toilet waste water to permit discharge of the treated water to the atmosphere during flight, utilizing the pressure differential that is created between the aircraft's cabin pressure and the external atmosphere. The system includes a filter to remove suspended solids and other contaminants from the waste water, and may also include means to purify the water to potable water standards and means to recirculate the treated water for re-use on the aircraft.
Claims7
A method of treating aircraft toilet waste water, comprising evacuating waste water from a holding tank for a toilet system utilizing a pressure differential between the pressure within the aircraft cabin and the external atmosphere when the aircraft is in flight wherein the contents of the holding tank comprise waste water, settled solid particulate matter, and suspended solid particulate matter, the evacuating does not dehydrate the settled solid particulate matter, and the evacuated waste water is free from settled solid particulate matter, filtering the evacuated waste water to remove suspended solid particulate matter and other contaminants, and discharging the filtered water to the atmosphere.
