Abstract
The invention relates to a method of remi-neralization and correction of pH for water produced by a fuel cell (P) on board an aircraft, noteworthy in that it consists in diverting part of the water (E1) produced by the cell to at least one treatment tank (200) containing a saturation reagent and in mixing the flow of treated water (E2) issuing from the treatment tank (200) with the undiverted flow of water (E3) so as to obtain water (E5) with the desired mineralization and/or pH. The invention also relates to devices making it possible to implement said method.
Claims19
A device for remineralization and pH correction of water produced by a fuel cell in a confined space, the device comprising:
- a saturation reagent;
- a first tank;
- a first treatment tank containing the saturation reagent;
- a second tank;
- the tanks arranged top to bottom in the order of the first tank, the first treatment tank, and the second tank;
- means for providing a flow of treated water from the first treatment tank;
- a first conduit leading from the bottom portion of the first tank into a bottom portion of the first treatment tank;
- a second conduit leading from the top portion of the first tank to a top portion of the second tank;
- a third conduit leading from the top portion of the first treatment tank, through which treated water is discharged, rejoining the second conduit whereby mixing occurs at the intersection of second conduit and third conduit;
- and
- a control valve in conduit upstream of conduit so as to obtain water with the desired mineralization or pH.
Apparatus for remineralization and pH correction of water, the apparatus including:
- an aircraft;
- a fuel cell on board the aircraft, the fuel cell producing water;
- a saturation reagent;
- a first tank;
- a first treatment tank containing the saturation reagent;
- a second tank;
- the tanks arranged top to bottom in the order of the first tank, the first treatment tank, and the second tank;
- means for providing a flow of treated water from the first treatment tank;
- a first conduit leading from the bottom portion of the first tank into a bottom portion of the first treatment tank;
- a second conduit leading from the top portion of the first tank to a top portion of the second tank;
- a third conduit leading from the top portion of the first treatment tank, through which treated water is discharged, rejoining the second conduit whereby mixing occurs at the intersection of second conduit and third conduit;
- and
- a control valve in conduit upstream of conduit so as to obtain water with the desired mineralization or pH.
