A method of draining grey water contained in a holding tank of a system for management of grey water in aircraft toilets, comprising:
- draining the grey water through an undulating diaphragm pump comprising an inlet conduit connected to the holding tank, the pump diaphragm being able to undulate between two flanges for draining the said grey water present in the holding tank through the inlet conduit of the pump to a discharge conduit of the pump.
A system for management of grey water in aircraft toilets, comprising a washbasin, a water supply valve of the said basin, a grey water drainage system of the washbasin connected to a holding tank, which is equipped with a filter, and a bowl connected to the holding tank, and a main grey water tank, the bowl and the holding tank being connected to the said main tank by conduits, wherein the system comprises an undulating diaphragm pump having an inlet conduit connected to the holding tank and a discharge conduit connected to the bowl, the pump diaphragm being adapted to undulate, by way of actuating means, between two flanges for draining the said grey water present in the holding tank through the inlet conduit of the pump to the discharge conduit of the pump in order to supply grey water to the bowl.
A system for management of grey water in aircraft toilets, comprising:
- a diaphragm pump having an inlet conduit connected to a holding tank and a discharge conduit connected to a bowl, the diaphragm pump being selectively undulated between two flanges for draining grey water present in the holding tank through the inlet conduit to the discharge conduit of the diaphragm pump to supply grey water to the bowl.
