Abstract

A compact dehydration engine and method for treating human waste and gray water residual electro-coagulants that includes a heated waste dehydration chamber that has low energy consumption and low water consumption in use. The system can be employed in stationary or mobile platforms that include multiple toilets and gray water sources for reclamation.

Claims (15)

1. A system for reducing human body waste to a dry powder that is safe for disposal comprising:

a dehydration engine for waste products;

a self-contained dehydration toilet having a flush bowl, a fresh water holding tank, and a toilet lid;

a source of ozone connected to said holding tank to reduce odors;

a dump valve manual handle;

a dump valve connected to said manual handle to activate said dump valve, which connects said toilet flush bowl directly as an input to said dehydration engine, and which can be activated by manual operation of the manual handle to release water from the holding tank and ozone into the flush bowl so that its contents flow into the dehydration engine;

said dehydration engine including a dehydration engine chamber having one or more cylindrical chambers mounted side-by-side connected to said toilet flush bowl by said dump valve;

said cylinders including one or more elongated electric heating elements mounted around the periphery of each cylinder for heating waste flushed from the toilet;

an electric power controller connectable by a plug to an electric power source and is connected to each heating element on the outside walls of said cylinders and which activates said heating elements at predetermined times;

a plastic helical blade disposed longitudinally within each of the cylinders for stirring the waste, including a blade member having numerous apertures throughout to allow liquid to pass through and a blade shaft;

a motor;

said blade shafts being engaged with said motor connected to said controller which can rotate said helical blades in alternating directions within the chamber and which is activated by said controller for the heating elements; said controller for the electrical power to the heating elements;

said controller for the electrical power to the heating elements including a software program that determines by temperature sensing and time the most efficient power curve for the heating elements thereby activating said heating elements after a predetermined number of flushes to evaporate the water;

a steam conduit connection to said cylinders; and

an exhaust fan activated once the temperature within the dehydration engine reaches 212 degrees Fahrenheit, which is connected to said dehydration engine and also is connected by said steam conduit as an output to a said freshwater holding tank so that steam is removed from said engine through a stream vent into said steam conduit to the freshwater holding tank as recovered condensate water.
