Abstract
The toilet system includes an evaporator tank having an inlet and an outlet that is at the top portion of the tank, a first electrical heater mounted on the tank, macerator/transfer pump means connected to the inlet of the tank to transfer flushed waste from a toilet to that tank, a vapor treatment system including a vessel having an inlet and a vent outlet and containing a bed of catalyst, first conduit means connected to the outlet of the tank and to the inlet of the vessel to transfer vapor from the tank to the vessel, a second electrical heater mounted on the conduit means to heat vapor passing from the tank to the vessel of the vapor treatment system, and second conduit means connected to the first conduit means between the mounting of the second heater and the evaporator tank to introduce pressure air into the vapor from the tank before the heating of the vapor. The toilet system further includes means mounted in one of said first and second conduit means and responsive to a condition indicative of inadequate pressure of air in said second conduit means to prevent continued operation of the second heater. The toilet system has low-level sensing means mounted in the evaporator tank that is operative, when the level of liquid waste in that tank is below a predetermined low level, to prevent the operation of the first heater. Also mounted in the evaporator tank is high-level sensing means that is operative, when the level of liquid waste in the tank has raised to a predetermined higher level to prevent the operation of the macerator/transfer pump means until the level of liquid in the tank is lowered by evaporation of water from the liquid waste in the tank or the discharge of liquid waste from the tank.
