Where do the toilets on airplanes go?

For large aircraft, vacuum toilets are generally used. There is a sewage tank, the sewage tank is pumped into a vacuum, when you need to pump poop, open the one-way valve can be directly pumped into the sewage tank and stored on the ground for treatment. The water needs a little bit, that is, to the sidewall.

The water in the sewage tank is not reusable.

For small business jets, they generally have their own sewage tank, and its water needs to be reused, and special detergents are added to the sewage tank, so that the feces will not smell.

The water you wash your hands is drained directly from under the plane.

The dirt of the toilet is stored in the plane, and every time the plane is parked, it needs to be pumped out by a sewage truck.

Aircraft like the 330 can see the dissatisfaction of the sewage.

That one.

The aircraft's toilet system includes a sewage tank where dirt is temporarily stored and removed after landing. And the water in it is recycled. The water used to flush toilets on airplanes is actually dirty water.

Now the newer planes are all vacuum pumps, and the older ones are not, for example, the 737-300 is a flushing toilet, and the 737NG is a vacuum pump. Even larger aircraft such as the 757 have flushing toilets, which have nothing to do with the size of the aircraft.

Haha, if that's the case, it's going to be messy.

It's not raining anymore, so it's going to be that one. Ha ha.

There is specialized equipment on the plane!!

"Clutch! What kind of thing stinks! Grid is the big hand of the Air Force"

It's a big bag stored in the plane, it's a compression bag.
