Abstract: A disposal system utilizing a direct injection of water for an amount of time to sufficiently sanitize a chamber of the disposal system. The disposal system includes a chamber coupled to a drain of a sink at a first end of the chamber, and to a drainpipe at a second end of the chamber. A cutting mechanism, such as a rotary cutting blade, is positioned within the chamber near a floor of the chamber. A fluid-injection unit, such as a flange attachment, coupled to the first end of the chamber and the drain of the sink, includes a plurality of nozzles for introducing a fluid in a variety of streams in different directions to reach substantially an entirety of the chamber. The flange attachment can also include a water line attachment for connecting to a water line, with an optional ozone generator upstream from the disposal system.

Abstract: A sink system includes a sink basin and a disposal system. The disposal system includes a first inlet coupled to the sink basin, a second inlet fluidly coupled to a second fluid source, and a garbage disposal configured to receive a first flow of fluid from the sink basin via the first inlet and receive a second flow of fluid from a second fluid source via the second inlet. The sink basin delivers a flow of used water to the disposal system and the second fluid source delivers a flow of clean water to the disposal system.
