  • Publication number: 20100116935
    Abstract: The invention relates to a vacuum toilet system for transporting toilet waste water and for collecting the waste water in an aircraft. The vacuum toilet system comprises a waste water transport tank and a waste water collection tank that is always subjected to a cabin pressure. In this case, the vacuum toilet system is designed in such a way that the transport of the waste water through the waste water transport tank takes place in combination with a pressure difference between the toilet and an outboard ventilation. The waste water is collected in a waste water collection tank. In this case, the waste water collection tank may be realized in the form of a conform, unpressurized waste water collection tank.
