WATER/WASTE SYSTEM Flashcards
How does the toilet system work?
Differential pressure forces waste from the toilet bowls into the waste storage tank. On ground and in flight at altitudes below 16,000ft a vacuum generator produces the necessary pressure differential. Clear water from the potable water tank flushes the toilets.
What is the capacity of the potable water tank?
Potable water is stored in a 200 liters tank in front of the wing box behind the forward cargo compartment.
Where can you control the water and waste system?
The water and waste control panel is on the forward cabin attendants panel.
What is the capacity of the waste tank?
The waste tank has a usable capacity of 170 liters.
What is the purpose of the water and waste system?
The water and waste system distributes potable water to the toilets and the galleys.
It also disposes waste water and store toilet wastes.
How is the water system pressurized in the air and on the ground?
By Bleed Air when airborne and by air from the service panel pressure port
How is the water/waste system protected from ice build up?
Systems are insulated
What happens with the waste water from the galleys and lavatories?
It drains overboard through two heated drain masts
How is waste from the toilet bowls moved to the waste tank?
By differential pressure
