There are described methods and systems for supplying water to an aircraft. A water supply assembly is fluidly coupled to a water storage tank via a supply line. An overflow line is fluidly coupled to the water supply assembly. One or more sensors are configured to determine an amount of water in the water storage tank. One or more processors are communicative with the one or more sensors and configured to: determine a desired amount of water to be contained in the water storage tank; determine from the one or more sensors that an amount of water in the water storage tank corresponds to the desired amount of water; and, in response to determining that the amount of water in the water storage tank corresponds to the desired amount of water, transmit an instruction for causing water being supplied from the water supply assembly to the water storage tank to be diverted to the overflow line.

A sea water intake unit comprising a source of air (12), a substantially vertical pipe (10) having an air inlet and a sea water inlet for air lifting sea water in the substantially vertical pipe to a height above sea level, the depth of the inlet below sea level being sufficient to promote air lifting of the sea water to the height above sea level. The air lift delivers sea water to a pre-treatment filter unit (22) in fluid communication with the vertical pipe in which the rate of flow of the sea water is such as to separate out small marine life in an upper portion of the water from the lower filtered portion, and a discharge pipe (40) to return at least some of the sea water and marine life back to the sea. The intake unit may deliver the lower filtered water to a desalination plant (6) provided on a disused offshore platform (2).

Systems and methods for operating a potable water system in an aircraft are provided. Aspects include determining, by a controller, flight data associated with a flight for the aircraft, determining passenger data associated with the flight, determining an estimated water consumption for the potable water system associated with the aircraft based on the passenger data, determining a water quantity value for the flight based at least in part on the flight data and the estimated water consumption, and transmitting, by the controller, a request for the water quantity value for the potable water system for the flight to a water fulfillment system.

A waste water filtration system filters polluted waste water from various waste water sources including fire sprinkler systems and fire hydrants. The system may be connected by a pipe or hose to a fire sprinkle system riser or stand pipe. The filtering system includes a stainer to capture large particles, a fine particle filter to capture small particles, and may include a chemically selective sponge to capture, for example, oil, and destroy bacteria, when necessary. A switch senses the presence of liquid and turns on a pump when required to advances liquid through the fine particle filter. The filtering system preferably allows compliance with NFPA Standards, California State Fire Marshal's and the California Water Resources Board Best Management Practices (BMP) for maintaining fire sprinkler systems, and Federal Clean Water laws, Federal Coastal Zone laws, and local city ordinances for releasing liquids into storm drains.

A system for injecting an aqueous solution into an injection engine, includes: a tank for an aqueous solution, a circuit for supplying aqueous solution to the tank and a filter for filtering the aqueous solution, and a circuit for recirculating the aqueous solution. The injection system also includes recirculation of the aqueous solution, and is provided with an electrovalve including a first inlet connected to a filler neck of the tank, a second inlet connected to the recirculation circuit, and an outlet connected to the supply circuit. The filtration filter is arranged in the supply circuit and/or in the recirculation circuit.

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.

Electro oxidation membrane evaporator 1 comprises sweep air handler 60; fluid tank 20 defining a fluid container; fluid contactor/separator 30; oxidation cell 40; and scrubber 80. Electro oxidation membrane evaporator 1 may allow higher percent water recovery from wastewater prior to delivering brine to a brine water recovery system and can allow O.sub.2 from air such as cabin air to continuously diffuse into the wastewater as O.sub.2 is consumed to generate oxidants, helping to eliminate the low oxidant environment at the end of the cycle that causes pH to remain high, and low pH prevents precipitates from forming for longer so more water can be evaporated from the wastewater.

The present disclosure relates to a biocide generating system for inhibiting bio-fouling within a water system of a watercraft. The water system is configured to draw water from a body of water on which the watercraft is supported. The biocide generating system includes an electrode arrangement adapted to be incorporated as part of an electrolytic cell through which the water of the water system flows. The water system is configured such that biocide treated water also flows to one or more components of the water system that are positioned upstream of the electrode arrangement.

A method, an apparatus, and a system for treating a waste in a vehicle. The waste is received from a lavatory in a waste tank through a waste input port connected to the lavatory in the vehicle. Anaerobic bacteria are introduced into the waste such that anaerobic digestion occurs to breakdown a biodegradable material in the waste in the waste tank.
