ABSTRACT:
Improvements in a recirculating toilet system wherein at least one human waste receiving receptacle, such as a urinal or toilet bowl, is provided coupled to a separating tank having a predetermined amount of a non-aqueous flushing fluid of a lower density and specific gravity than water therein. A flushing fluid intake floats on top of a layer of the flushing fluid in the tank with water and human waste below the layer. A motor-activated pump flushing fluid recirculating means is coupled to both the intake and the receptacle for withdrawing flushing fluid from the layer in the tank and flushing the receptacle. The float has a detector for detecting the presence of a predetermined amount of wastewater in the flushing fluid being withdrawn from the tank for flushing the receptacle and for detecting the level of the flushing fluid in the tank and deactivates the pump of the recirculating means when this predetermined amount of wastewater is detected.
