ABSTRACT:
A system for treating human waste in remote or portable toilet facilities, including a holding tank that stores waste; a heat reservoir that receives waste from the holding tank, heats the waste to kill fecal coliform bacteria therein present, and routes the heated bacteria-free waste back through the holding tank. The holding tank maintains the heated bacteria-free waste separate from the contaminated waste but passes residual heat from the bacteria-free waste to the untreated waste. In one embodiment, a centrifuge receives the bacteria-free waste from the holding tank, separates the liquid waste from the solid waste, and discharges the liquid waste from the system. In one embodiment, the waste is pumped through the system to be heated in incremental portions.
