In a tri-flush toilet, three operational flush modes may be provided to enable water conservation. The toilet may include a third mode operating a peristaltic pump to reduce the water consumption per flush. The peristaltic pump is operably connected to evacuate fluids and/or solids form the toilet bowl.

A waterless urinal for a vehicle, the urinal including a fluid bowl having a drain, and a waterless urinal cartridge disposed within the drain. The cartridge includes a housing having a waste reservoir disposed within the housing that holds a predetermined volume of urine, and a drainage aperture configured so that an amount of urine exceeding the predetermined volume of urine flows through the drainage aperture to exit the housing. A cover is coupled to the housing and forms part of a surface contour of the bowl, the cover includes a sealing fluid reservoir and fluid passages for directing urine from the bowl to the sealing fluid reservoir. The sealing fluid reservoir is in conmmnication with an internal cavity of the housing, the waste reservoir includes at least one fluid flow control feature configured to restrain urine movement within the waste reservoir in response to a change in vehicle dynamics.

A waste fragmenting toilet apparatus with pressurized water jets is disclosed. The apparatus includes a toilet bowl, a toilet trap, a water supply, and a plurality of oscillating water jet nozzles. The oscillating water jet nozzles are located within line of sight of recurrent waste blockage zones, interior to the toilet trap and/or toilet bowl. When actuated, the oscillating water jet nozzles inject pressurized water into a trap area breaking up waste material as it passes through. The oscillating water jet nozzles may be used to preemptively prevent blockages and to remove existing blockages.

A wastewater management system 10 includes a black water tank 12 for holding black wastewater and a grey water tank 14 for holding grey wastewater. The system 10 may additionally include a filter 62 for filtering suspended solids from the grey water; a first conduit 64 between the grey water tank 14 and the filter 62; a second conduit 66 between the filter 62 and a toilet 22, and a third conduit 68 between the filter 68 and the black water tank 12, the third conduit 68 associated with a valve 26; and a fourth conduit 69 between the filter 62 and the grey water tank 14, the fourth conduit 69 associated with the valve 26. The system 10 further includes a control sub-system 38 in communication with the valves 26 for controlling valves 26 to deliver filtered grey water to the toilet 22 for flush and to periodically clean the filter 62 of captured solids and deliver the captured solids to the black water tank 12. A related method for managing wastewater within a recreational vehicles with the wastewater management system 10, an apparatus for delivering wastewater from a recreational vehicles to a drain and an additive sub-system 54 for wastewater management system of a vehicle are also provided. Further, the present teachings relate to a system 10 including a housing associated with a toilet 22, the housing including a valve and a macerator pumping arrangement 34 including a macerator 34a and a pump 34b that work independently from one another, the macerator 34a including a plurality of macerating knives 37 driven by a first motor 35a, the pump 34b providing positive pressure, the macerator pumping arrangement 34 is operative in a macerating mode and a pumping mode, such that the first motor 35a first drives the macerating knives 37 to macerate the waste and subsequently, the pump 34b pumps the waste out of the housing 34a.

An obstruction clearing assembly for clearing an obstruction from the P-trap to the waste outlet of the toilet. The assembly is positioned inside the toilet is accessible and controlled outside the fixture by a foot pedal which is connected to a flexible cable, which are aligned diagonally by a plurality of at least a dozen threads located outside of the assembly. A cable is connected to a chain with multiple joints and rotates the pulley wheels and rotors inside the assembly. The rotors move in conjunction with the obstruction inside the pipeline. A sleeve provides a rigid frame for the cable. A tensioner connects the cable and the cross bar. The pulley rollers change the direction of the cable from a diagonal to a vertical position and vice versa while the cross bar holds the tensioner that is connected to the chain and toilet base.

A water turbine and electric motor hybrid power suction type water-saving toilet, with toilet main body comprising a hollow frame, a hollow frame water inlet, a basin bottom water injection hole and an S-shaped bend, wherein the hollow frame is located on upper part of the toilet with water injection holes distributed along the periphery towards inner side of the toilet; the hollow frame water inlet is formed in rear part of the toilet; the basin bottom water injection hole is formed in lower part of the toilet and communicates with the hollow frame water inlet through a pipe cavity attached to outer wall of the toilet; and a basin bottom water injection valve is arranged at the opening of the basin bottom water injection hole leading to the S-shaped bend and controls connection/disconnection of basin bottom water injection hole and S-shaped bend inlet section with water pumping process synchronously.

We disclose a toilet system which analyzes solid waste to detect tags which were associated with pharmaceutical or nutritional products and excreted in the solid waste of a user. The toilet system may include a receptacle for receiving solid waste, a liquid dispenser for providing a liquid to assist in dispersing the solid waste, a solid waste dispersing system which may mix the solid waste with the liquid thereby homogenizing the solid waste, and an electromagnetic signature detector which may analyze the tags in the solid waste. The electromagnetic signature detector may include a selective binding surface which may bind tags present in the solid waste and which may be connected to a transducer which senses the presence of bound tags.

A wall-installable macerator pump includes a tank, which is configured to house a macerating assembly. The width of the tank is configured to be positionable inside a cavity defined inside a wall. The macerating assembly comprises a motor, a pump cavity, and a chopper pump positioned inside the pump cavity. The motor receives sewage material through a sewage inlet, and sullage material through a sullage inlet, where the sewage inlet and the sullage inlet are positioned on the tank. The pump cavity receives the sewage material and sullage material, and a combination of the sewage material and sullage material defines a combined waste. The chopper pump positioned inside the pump cavity macerates and pumps the combined waste through a discharge outlet positioned on the tank.
