    Abstract: A portable toilet system is provided having an enclosed housing and including a tank upon which a toilet seat and bowl is positioned. The tank has two sections divided by a wall. Waste drops into the first section where it is accumulated for collection. The dividing wall does not extend to the top of the tank. The second section is initially filled with fresh water. A pump draws water through a hose or pipe submersed in the second section. That water is flushed into the toilet bowl to rinse waste into the first section. As the water in the second section is depleted, the liquid waste deposited in the first section overflows the dividing wall into the second section of the tank to recycle the liquid waste and extend the period before servicing of the system is necessary.

    Abstract: A compact and easily transportable temporary flush toilet can be installed where the toilet cannot be connected to a water supply system and no frequent maintenance is possible. The temporary toilet includes a toilet bowl, a flush water tank for storing flush water used to flush the toilet bowl, a sewage tank for storing sewage from the toilet bowl, a water vapor separator for separating water from gas containing water vapor vaporized from sewage in the sewage tank, an exhaust pipe through which gas is guided from the top of the sewage tank to the water vapor separator, and a distilled water pipe through which water separated from the gas in the water vapor separator is supplied to the flush water tank. Thus, storage of the sewage, microbial decomposition of waste, and evaporation of the sewage take place in the sewage tank alone.

  • Patent number: 8449239
    Abstract: A bracket assembly for vehicle waste tanks having first and second longitudinal frame members. The longitudinal frame members each have proximal ends and lateral edges. In addition, the longitudinal frame members each have sidewalls extending therefrom. The sidewalls extend from their respective proximal ends a predetermined distance. Each proximal end has hinge assemblies that mount onto a vehicle. In the preferred embodiment, the bracket assembly for vehicle waste tanks is mounted onto an underside of the vehicle, so that it is not seen and does not obstruct any functionalities of the vehicle, which may be a recreational vehicle having a kitchen, a bathroom, a bedroom and a living room. The vehicle may also be defined as a caravan, camper, or camper van. The vehicle is intended for everything from brief leisure activities such as vacations and camping, to full-time living, for which they are often parked in special trailer parks.

    Abstract: An on-demand waste transport system and method may be used for transporting waste from low or no water disposal devices (e.g., low flow toilet fixtures, foam flush toilets and similar types of reduced water toilet fixtures) to remote areas (that may not be functionally accessible by gravity) via an evacuation system. These areas may include, but are not limited to, composting units, sewers, septic systems, holding tanks or areas where the waste may be combined with additional water. The system and method may transport the waste by generating an “on-demand” vacuum pressure within the system.
