ABSTRACT:
A waterless flush toilet system comprising at least one toilet and a gravity fed waste holding tank. The system utilizes a recirculating nonaqueous flushing fluid which is stored within the holding tank. The fluid, which is lighter than the waste material and insoluble therein, forms a stratified layer on the surface of the material. A float having a flushing fluid inlet floats within the layer of fluid, the float being suspended from the top of the tank by a flexible coiled hose which is coupled to the fluid inlet. The coiled hose contracts as the waste level in the tank rises, thereby permitting the float to remain within the flushing fluid layer regardless of the waste material level. When the toilet is flushed, an electric or air-powered pump draws a fraction of the fluid into the fluid inlet of the float, through the flexible hose and finally to the toilet. The fluid serves as a medium for transporting the waste material from the toilet to the holding tank. When the fluid is flushed into the tank, it separates from the waste material and returns to the stratified layer for reuse. The system includes a floating member which automatically prevents loss of the flushing fluid when the holding tank is drained. Two embodiments of the system are disclosed with a first embodiment system comprising a single toilet and single waste holding tank and a second embodiment system comprising a plurality of toilets coupled to a single tank.
