Abstract: Methods and systems for equipping a toilet with hygiene and safety features by controlling and reducing potential escape of liquid waste from the toilet.

Abstract: A fluid recycling unit for use on board an aircraft or other passenger transportation vehicle. The fluid recycling unit captures various types of used fluids, filters or otherwise appropriately treats the fluids, and recycles the fluids for various uses onboard the vehicle.

Abstract: A drain ball valve for an aircraft tank. Particular embodiments find use in connection with aircraft waste tanks. The drain ball valve has an upper shell that is shaped to be received within a tank drain plumbing line. The drain ball valve has a lower shell shaped to receive a funnel and/or a bellow component in order to help direct waste or other fluids exiting the tank.

Abstract: Embodiments of the present disclosure relate generally to a toilet bidet system for use on a passenger transportation vehicle. In particular, there is described a bidet rinse ring that converts a standalone toilet to a combined toilet and bidet system. Designs find particular use onboard passenger transportation vehicles, such as aircraft. Such systems benefit from efficient space management and generally cannot support a separate toilet and bidet. The bidet rinse ring described herein may come factory-mounted on the toilet. In other examples, the bidet rinse ring may replace a standard rinse ring in order to retrofit an existing toilet.

Abstract: Embodiments of the present invention provide systems and methods for disposal of liquid and food into a sink basin. The disclosed system cooperates with and delivers the received waste material to the main waste system on-board the vehicle. This is typically an aircraft waste tank. The system does not require a manual flush, but includes a sensor system that activates drainage of the holding line when the liquid and/or other waste material reaches a certain level therein. The disclosed system combines the functionalities of a common galley sink and a galley waste disposal unit, but occupies only the space envelope of an existing galley sink. The use of an existing galley sink means that no additional space on the countertop is required.
