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.

Abstract: A process and system for continuously recovering industrial waste water characterized as divergent hydro-lipophilic waste streams for industrial reuses to enhance water conservation and to reduce environmental pollution is disclosed. The process and system are especially suited for reclaiming animal and food processing discharge water having blood, fat, oil and grease contaminants in the water, for industrial reuse in evaporative condensers, hydraulic system cooling and equipment, non-food contact vehicles and plant or factory area wash-downs. The process can operate continuously for supplying water for such industrial uses, but also includes an automatic shut down if the incoming influent to be treated is too turbid. The process includes chemical pH adjustment, separation of fat, oil and grease (FOG) from the influent and particulate removal in polishing filters. Sensors are used to monitor the pH and component internal water pressures throughout.
