The present application generally relates to aircraft water management. The disclosed system provides an initial step of verifying the amount of available water on board and dynamically regulating water usage during flight based on projections and comparisons between projections and actual usage. The system implements a series of water conservation strategies modeled on historical data, using a control system to manage water usage.

Methods, systems, and apparatuses for temporarily increasing, on demand, the relative humidity of an area located proximate to a user in environments having lower than ambient relative humidity are provided by integrating a personal humidification circuit into a water delivery circuit to provide a diverted flow of water, and provide a flow of water vapor to a user, and returning the relative humidity-enhanced environment to a predetermined relative humidity by purging the environment.

The invention relates to a system and to a method for purifying faecal-free and surfactant-containing domestic wastewater, in particular grey water and kitchen wastewater. An electrochemical treatment unit (3) and a device for introducing gas (11, 12, 14) are provided. Furthermore, at least two dirty water tanks (1, 21) are present, wherein domestic wastewater to be purified is fed to the first dirty water tank (21) from at least one first consumer, and wherein domestic wastewater to be purified is fed to the second dirty water tank (1) from at least one second consumer. In addition, at least two clear water tanks are present, wherein the purified domestic wastewater originating from the first dirty water tank is fed to the first clear water tank (22), and wherein the purified domestic wastewater originating from the second dirty water tank is fed to the second clear water tank (6).

A waste fluid treatment apparatus removing processing debris from a processing waste fluid discharged from a processing apparatus. The waste fluid treatment apparatus includes a fluid bath storing the processing waste fluid, an inflow port through which the processing waste fluid is introduced to the fluid bath, a collecting area having an inclined surface for depositing the processing debris at a predetermined portion of a bottom of the fluid bath in a concentrated manner, a vacuum pump discharging the processing debris deposited in the collecting area to an outside of the fluid bath, and an outflow port through which a processing waste fluid obtained by removing the processing debris is discharged.

A water delivery system for delivering demineralized water to a consuming unit of a motor vehicle, in particular to a combustion engine, encompassing: a water tank having a filling opening; a first aspiration line; a first water pump; a discharge line; a discharge apparatus; a demineralization apparatus for demineralizing water; the first water pump being fluidically connected via the first aspiration line to an internal volume of the water tank; the discharge apparatus being fluidically connected via the discharge line to the first water pump.

A potable water filter for an aircraft galley plumbing system is disclosed. In embodiments, the filter includes a body attachable to a mount via a central threaded attachment stud. The stud is surrounded by a filter mount chamber and encloses a central flow channel allowing outflow from the filter body to an outlet port. Potable water enters the mount through an inlet port including a barrel valve that opens to allow water flow when the filter body is screwed onto the stud, and seals off the filter mount chamber when the filter body is absent. The outlet port includes a check valve to prevent backflow into the filter. The filter body houses a solid block of sintered carbon with a hollow core. Water enters the filter chamber and flows around and through the carbon filter before flowing down to the outlet port. The filter body self-vents at its top.

A portable floating sea water desalination system is presented to realize ultra-high efficiency and extremely low cost water purification. The disclosed system comprises an inflatable non-imaging solar concentrator based compact desalinator subsystem, a photovoltaic powered distillation subsystem, and an inflatable rubber boat system. The inflatable non-imaging solar concentrator concentrates both beam light and diffuse light into an envelope type evaporator to evaporate the brine water to realize extremely low cost. A nano materials absorber is incorporated into the evaporator to realize ultra-high efficiency. A portion of the heated brine water contained in the evaporator is circulated to the photovoltaic powered distillation subsystem for further evaporation. Both of the subsystems above are mounted on the inflatable rubber boat subsystem for portability.

The vehicular water-dispensing method incorporates a water recovery process, a water STT process, and a discharge process. The water recovery process: a) converts water contained in a gas phase in the atmosphere into water in a liquid phase; b) initially treats the converted liquid phase water to remove microorganisms and other chemical contaminations; and c) transports the initially treated liquid phase water to the water STT process. The water STT process: a) receives and stores the initially treated (liquid phase) water from the water recovery process; b) subsequently treats the stored water with a final treatment to remove microorganisms and other chemical contaminations; and, c) transports the treated stored water to the discharge process. The discharge process: a) receives the water from the water STT process after the final treatment; and, b) controls the discharge of the water received from the water
