Space toilet: urine recycled into drinking water

Jennifer Pruitt is a lead engineer in converting urine into drinking water, a position she loves
In addition to its primary function, a toilet aboard the International Space Station (ISS) provides crew drinking water. But so far, the cleaning system is not working as well as planned. Correspondent
BBC Future investigated the issue.
Jennifer Pruitt has perhaps one of the most unusual positions in the US space agency NASA, if not in the entire space industry.
She is the lead engineer for converting urine into drinking water.
“A job title is one of the things I love about my job,” says Pruitt, proudly speaking. “There aren’t many people in the world who deal with this problem.”
Pruitt is working on improving the water recovery system aboard the ISS. Its laboratory is located at the George Marshall Space Flight Center in Huntsville, Alabama.
Pruitt’s challenge is to find the most efficient way to convert astronaut urine into drinking water.
(Similar articles from the “Journal” section)
Our urine is 95% water (the rest is waste products of the body). The more water that can be reclaimed from urine flowing into the two toilets aboard the ISS, the less it will need to be transported from Earth on costly cargo flights.
There is a small display in the reception area at the entrance to Pruitt’s lab. On the shelf are bottles of urine, varying in color – from the usual light yellow to brown and even black.
Russian urine with additives
To my surprise, the liquid in the bottle labeled “Pretreated American Urine” is much lighter than in the bottle of Russian urine next to it.
I am wondering what is the reason for this difference.

“The Russians are fine,” Pruitt reassures me. “Their urine is no different from ours.”
The ink black liquid is actually not pure Russian urine, but with the addition of chemicals used in the processing of urine.
“We can’t use urine in the form supplied by the ISS crew for regeneration,” explains Pruitt.
This pre-treatment is just the beginning of a complex process used by NASA to reclaim water aboard the ISS. The moisture filtered from the air inside the station is added to the water extracted from the urine – mainly in the form of sweat from astronauts. This liquid is then converted into drinking water. According to NASA calculations, during a 12-month expedition, each member of the ISS crew should, on average, have 730 liters of drinking water regenerated from urine and sweat.
Abnormal blockages
But there is one problem.
While the sweat water extraction system works as expected (virtually all the moisture in the air is recycled), the performance of the urine treatment system has not yet been as expected. In the ground laboratory, the productivity is 85%, that is, only 15% of the water contained in the urine is irretrievably lost. But on board the ISS, only 75% can be extracted.

Periodic blockages cause ISS crews to spend time repairing toilets
“Calcium is leached from the bones of astronauts in space. We did not take into account in our calculations exactly how it is excreted from the body,” says Pruitt. “As it turns out, a significant part of the calcium lost is excreted in the urine.”
This means that the urine of astronauts in space has a different chemical composition than the urine of volunteers from the Marshall Center, which NASA specialists work with on Earth.
“It has been found that the high calcium content in the urine reacts with the chemicals used to treat it,” says Pruitt.
One can imagine all the drama of such a situation – a company of six people in a closed space at a distance of 400 km above the Earth’s surface and … with a non-working bathroom. Due to periodic blockages, ISS crews have to spend time repairing toilets, and more water is delivered to the ISS than originally planned.
But Pruitt’s team found a solution to this problem. By changing the composition of the chemicals used to treat urine, the researchers hope to improve the efficiency of the ISS’s water regeneration system.
To test the new chemistry, Pruitt has a working model of the system laid out on a table in the giant hangar at the Marshall Center, where NASA develops and tests life support systems. A banner hanging from one of the beams under the roof informs visitors that the lab has been “saving the lives of astronauts since 1973”.
How the purification system works
The urine treatment system, a two-dimensional replica of the one in orbit, is a tangle of pipes, pumps, and wires connected to a huge tank of pre-treated, cola-like urine.
Pruitt tells me about how the gurgling machine works.
“The whole system is laid out horizontally to minimize the effect of gravity,” she explains. “Pumps work like the esophagus, contracting to force fluid through the system.”

Astronauts in space leach calcium out of their bones
We watch urine move through one of the transparent tubes to the largest vessel in the entire system, about the size of a home oven. The vacuum pump draws air out of the tank. When the pressure inside the vessel decreases, the boiling point of the liquid drops. This means that water can be excreted from the urine without heating it.
The liquid remaining after the primary distillation is sent back to the system in order to extract the maximum amount of water from it. As a result of the process, concentrated salty sediment and pure water are formed. On board the ISS, the sediment is packaged and placed along with the rest of the debris in a used cargo ship, which then burns up upon re-entry into the Earth’s atmosphere.
And the resulting water can be drunk again.
“This is the purest water,” says Pruitt. “It is purer than any water available on Earth.”
However, before astronauts can taste this ultra-pure water, it is further processed to prevent the spread of bacteria. Iodine is added to the water, which gives it a slight hospital flavor. “It’s not that terrible, it just takes some getting used to,” says Pruitt.
In just a few months – after a series of tests – NASA engineers expect to introduce a new formula of chemicals to the ISS. Thus, they hope, it will be possible to bring the volume of water regenerated in space to the laboratory level.
In the meantime, Pruitt’s team continues to improve the system.
“Despite years of working with urine, it’s still a very interesting job,” she says.

What does the color of urine say about health?
Even if the color of your urine changes every day, it should not be taken lightly.

What do these symptoms mean?

You can self-diagnose by looking at the color of your own urine. But even if this knowledge is only for information, the final diagnosis can only be made by a doctor after studying laboratory tests.
Contents of the article
What is urine for and what is it made of?
Urine is a waste product of the body’s metabolism that is produced in the kidneys. It is the end product of a complex process in which the kidneys filter gallons of blood daily to rid it of toxins. The result is urine.
A healthy person excretes 1.5 to 2 liters of urine daily. Thus, the body also regulates the balance of fluid and electrolytes (salts such as sodium and potassium).
Normally, urine is 95% water. The remaining 5% is urea and acid, salts, hormones, water-soluble vitamins and dyes. In general, a healthy bladder can store up to one liter of fluid. But most of us already feel the need to empty the bladder if it is one-third full.
What makes urine so yellow?
The yellowish color is due to the bile pigment bilirubin. It is formed due to the natural breakdown of the red blood pigment (hemoglobin). Bilirubin is mainly excreted in the feces, but a minimal part of it is also excreted in the urine.

What does the color of urine indicate? What color of urine is dangerous?
Clear and colorless urine
No danger. Urine becomes clear when it is very dilute. This suggests that you are obviously paying more attention to your fluid intake.
However: if you are still thirsty, this could be a sign of diabetes.
Light yellow urine
Very good. You are well hydrated.
Yellow urine
Everything is fine here too. There are no signs of illness. Urine color is still within normal limits. But take a bottle of water when you get the chance.
Dark yellow urine
This color often occurs in the morning. Because you drink little or no water at night, urea becomes very concentrated. The result is dark yellow urine. In summer, this coloration can also occur during the day, because then we sweat a lot and often do not drink enough fluids. You are not sick. But be sure to drink a large glass of water.
Cloudy yellow urine
See a doctor, consult a specialist. If the urine is cloudy, a bacterial infection is strongly suspected.
Dark yellow to orange urine
This may be due to too much bilirubin in the urine.
Possible cause: damage to the liver or obstruction of the outflow of bile (for example, due to gallstones). You may also have jaundice or certain medications (antibiotics). Contact a urologist.
Brown urine
Urine may contain blood. This is a sign of an infection or even a tumor. Consult a doctor! Brown urine can also appear during a fever or severe dehydration.
Reddish urine
Blood may be the cause. But there is no reason to panic. Traces of blood in urine are very difficult to see with the naked eye. More often than not, the cause is something harmless: foods like beets, blueberries, or rhubarb can turn your urine reddish. Medications also affect urine color and smell.
Light green to neon yellow urine
Do you take nutritional supplements? They can turn your urine into a bright waterfall. If you also experience pain or thick urine, this is a symptom of a urinary tract infection.
