Embodiments of the present invention provide a grey water flush system for use with vacuum toilets. One embodiment of the system provides a two-stage flush that uses a transient tank in between the toilet bowl and the main aircraft waste tank, which reduces the noise level associated with the flush process because a lesser vacuum is demanded for the first stage of the flush. Embodiments of the system further capture grey water from a sink basin in a reservoir and use that water in the toilet flush process. There is further provided a lavatory odor removal system option that is activated during the second stage of the flush.

A device for dispensing liquids from under the rim of a toilet by way of the toilet flush water is disclosed. The device includes a first arcuate bottle containing a first liquid and a second arcuate bottle containing a second liquid. The dispensing device has an arcuate base for holding the bottles. A wicking device supported by the base conveys liquid from the bottles to dispensing positions contacted with flush water. A hook is provided for suspending the base from a toilet rim. The majority of the upper surfaces of the bottles are not visible from above the rim of the toilet bowl when the dispensing device is installed on the rim, and the wicking device does not extend outward beyond an edge of the base. The bottles are at least partially spaced apart to define a flush water flow path between the bottles and through openings in the base.

A waterless vacuum toilet system for an aircraft includes a toilet bowl connected via a suction valve and a waste collection pipe to a waste collection tank. Waste-contacting surfaces that come into contact with urine and fecal waste are coated with an adhesion-inhibiting or adhesion-reducing nanocoating. The adhesion of waste is significantly reduced, and the need for flushing water is completely eliminated. Instead, an air jet arrangement preferably including an annular ring nozzle or annular air gap directs an airflow into the toilet bowl and along the nanocoated waste-contacting surface thereof, to "air flush" the waste material from these surfaces. The flushing airflow may be induced through the air jet arrangement into the toilet bowl by the suction applied through the suction valve. The "air flushed" toilet system substantially reduces the total system weight and eliminates the need for toilet flushing water to be carried in the aircraft.

A mechanism for raising and lowering a toilet seat in response to actuation of foot pedals. An actuation cylinder with a contained piston is connected between the toilet bowl and the toilet seat. Water from the supply line for the toilet is routed to the actuator cylinder when a seat up pedal is depressed and causes the piston to extend out of the actuation cylinder and raise the seat. Operation of a flush pedal causes the water within the actuation cylinder to drain so that the toilet seat lowers. A mechanical linkage from the flush pedal to the flush mechanism of the toilet links toilet flushing to the seat lowering action, ensuring that the seat is lowered after each flush.
