Abstract: A water system for a vehicle is provided. The water system comprises at least one water supply source, at least one water-conducting device, at least one closing valve and at least one germ reduction connection. The germ reduction connection and the water supply source are connected to the water-conducting device. The germ reduction connection is designed to introduce a germ-reducing fluid into the water-conducting device. The closing valve is arranged between the water supply source and the germ reduction connection and is designed to be fully closed thus preventing the ingress of germ-reducing fluid into the water supply source. By means of such a water system it is possible to carry out sterilization or disinfection very easily and quickly without this requiring any major maintenance work.

Abstract: A combined bidet and toilet system is provided for a toilet in transportation having a spray nozzle and a flow rate restrictor. The spray nozzle is adapted to provide a water supply to clean a user on the toilet. The flow rate restrictor is adapted to regulate the water supply on the basis of a water flow rate through the spray nozzle. The spray nozzle is adapted so that it is extensible on the toilet for use.

Abstract: A shower system for use in aircraft while in flight, the shower system having a feed line through which a stream of water can be supplied to the shower system; a showerhead from which a prepared stream of shower water can exit the shower system and a water stream parameter modification device for modifying at least one parameter of the water stream, said water stream parameter modification device incorporated between the feed line and the showerhead, wherein the water stream parameter modification device comprises at least one valve, which opens when not exposed to any pressure upstream to enable an evacuation of the entire shower system.

Abstract: An autonomous water module is provided for aircraft, preferably a water module embodied as a water trolley, and to a monument for aircraft, which includes, but is not limited to a device for receiving said type of water module, and finally, an aircraft equipped with said type of autonomous water module and/or said type of monument. The autonomous water module includes, but is not limited to a container having the standard dimensions of a trolley, and the container includes, but is not limited to a fresh-water tank, a device for dispensing fresh water, and a device for discharging gray water.

Abstract: A system is provided for water purification for a recirculation shower in a transport with a filtration unit, a first backwash line and a second backwash line. The filtration unit is designed to filter used shower water. The first backwash line and the second backwash line are designed to clean the filtration unit with a backwashing. The first backwash line is designed to convey backwash water to the filtration unit. The second backwash line is designed to discharge backwash water from the filtration unit.

Abstract: A toilet monument is provided, in particular for a passenger transport vehicle, which includes, but is not limited to a receptacle that is configured to receive a mobile sanitary unit. The mobile sanitary unit includes, but is not limited to components for operating the sanitary unit. The mobile sanitary unit may be removed completely from the toilet monument in order to make it possible to affect decentralized cleaning and servicing of the mobile sanitary unit. The term mobile sanitary unit refers, for example, to a toilet unit, a hand wash facility, a urinal or a shower unit.

Abstract: The present invention relates to a method for detecting residues on a component and particularly on the surface of the component. In order to also allow the testing of surfaces which are difficult to access, without the apparatus outlay growing, the method according to the present invention comprises the following steps: producing a base solution and a reference solution from water, producing a washing solution by adding fresh solvent to the base solution, filling the component to be tested with the washing solution, wetting the entire inner surface of the component with the washing solution, draining the washing solution out of the component, producing a test solution by adding the washing solution to the base solution, comparing the test solution to the reference solution, and testing whether a turbidity occurs in the mixing zone between the washing solution and the base solution, as proof for lubricant on the surface of the component.

Abstract: A water supply system, particularly for an aircraft such as a passenger aircraft, includes a disinfecting unit with an electrolysis cell connected in series with a water storage tank including a water distribution pipe system and a circulating pump. A bypass pipe with a valve permits connecting the electrolysis cell to the distribution system or bypassing the electrolysis cell. The electrolysis cell disinfects the water by anodic oxidation. A salt solution container may be connected to the electrolysis cell to enhance the anodic oxidation. The pump circulates the disinfected water through the tank and/or through the entire system, whereby the water supply is disinfected and the disinfected water in turn disinfects the entire system.
