  • Publication number: 20080307574
    Abstract: A portable composting toilet system has a compartmentalized receptacle for receiving human waste, a gray-water circulation subsystem for circulating gray water formed by mixing water with waste through the compartmentalized receptacle to promote mixing of the waste to thereby accelerate digestion of the waste, and an air-circulation subsystem for emitting air bubbles into a sludge formed at a bottom of the compartmentalized receptacle to break up the sludge to thereby accelerate digestion of the waste. The air circulation subsystem can include an air-driven pump that causes the gray water to circulate while allowing feeding pressurized air to diffuser loops in each compartment to create sludge-breaking bubbles. This portable composting toilet system so efficiently decomposes waste that the maintenance costs of hauling residual sludge to the surface (when the toilet is used underground in a mine) is significantly lower than for conventional toilets, thus providing substantial cost savings to mine operators.

  • Patent number: 7005077
    Abstract: A method and system for separating human waste solids from liquid for a shipboard toilet system that allows for the separation of solid waste, compaction of the solid waste and storage of solid waste. Wastes are deposited into a shipboard toilet system that uses vacuum toilets to flush waste into a large, inclined solid waste separation tank. A vacuum pump is attached to the separation tank to maintain negative pressure within the tank and system and to move the separated liquid stream. The separation tank has a separating screen disposed across its entire width to retain solid wastes while allowing liquid to flow through. After separation from liquids, solid waste material is compacted and dewatered with a helical screw through an inclined tube, and packaged for later removal as landfill or burned in the ship incinerator.
