Abstract: System and method for volume reduction solids treatment for fecal waste are described. The system can include a pasteurizer (102) configured to receive a slurry batch and heat the slurry batch at an elevated temperature for a time period to produce a pathogen free slurry. The system can also include a mechanical dewatering press (104) configured to compress the pathogen free slurry to separate a liquid phase from a volume reduced solid waste. The volume reduced solid waste being formed into a feces cake. The system can also include a means to remove the liquid phase and a drying tunnel (106) comprising a conveyor housed and an air duct system. The air duct system configured to propel forced air over the feces cake.

Abstract: System and method for micro-Super Critical Water Oxidation solids treatment of fecal waste are described. The system includes an injector vessel (112) and a reactor (114). The reactor can receive an injection of a slurry batch and an input of compressed air that is heated over time to a temperature at or above the critical point of water into the super critical fluid phase. A combined concentrator and phase separator (150)) can receive a treated output from the reactor and separate solid ash from liquid and gaseous effluent. A drying tunnel (170) can receive and dry the solid ash. The treatment process includes heating the slurry batch, within the reactor, to a temperature of at or above the critical point of water into the super critical fluid phase and maintaining the slurry batch a minimum temperature, within the reactor, for a predetermined treatment time to produce a treated output.

Abstract: System and method for collection and separation of human waste are described. The system can include a vessel (102) configured to receive human waste and a solids separator (106). The solids separator can include a vacuum tank as well as an inlet chamber formed within the vacuum tank at the top portion, a solids containment portion formed in the base of the vacuum tank and positioned centrally within the vacuum tank, a liquid containment portion formed in the base of the vacuum tank and contained within the vacuum tank surrounding the solids containment portion, and a separating filter having a cylindrical tubular shape and extending from the inlet chamber outlet to the solids containment portion. The separating filter forming a central separation volume within the vacuum tank. The inlet chamber is configured to receive the combined waste via an inlet (132) and to direct the combined waste to the central separation volume. The liquid portion of the combined waste allowed to flow through the separating filter to an outer portion surrounding the central separation volume and to collect in the liquid containment portion of the base. The solids portion of the combined waste contained within the central separation volume and collected in the solids containment portion of the base.
