The water purifier for the International Space Station has failed – Astronaut News


The water purification system installed on the American section of the International Space Station has failed and crew members will soon have to face repair.

The Water handler assembly WPA installed in the Tranquility unit has been discontinued due to a liquid leak. This tool is able to purify collected water from various sources and make it drinkable again. The crew is not in danger because on board the space station there are necessary spare parts for the repair and an adequate water supply.

Filtration, ion exchange, absorption, catalytic oxidation, and iodine are some of the wastewater treatment processes available in the system. Water handler assembly. This isn’t the first time WPA has failed, and it probably won’t be the last either. The space station has been in service for more than two decades and is increasingly showing signs of wear. In recent months, leaks have also appeared in the atmosphere that have weakened the oxygen supply and will require difficult and complicated repairs, and the astronauts on board have not yet discovered the true cause of this problem. A team of experts from the United States and Russia will begin investigating the matter at the end of May.

In August 2020, the International Space Station underwent an in-depth analysis that focused on the long-discovered, well-known, and preserved problem of atmospheric loss. Serge Krikalov, director of the human space program at Roscosmos, stated that the problem of atmospheric loss has been around for some time, but also explained that it was never a source of danger to the crew; However, the sudden deterioration of the situation prompted specialists in the field to prioritize this problem.

In its more than 20 years of operational life, the International Space Station has suffered from electrical problems, atmospheric leaks, malfunctions in water filtration systems, toilet malfunctions, and additional unplanned vehicle activities, even a problem. Ammonia contaminationThe worst situation, including the fire, could happen on the International Space Station. Fortunately, this warning turns out to be due to a sensor malfunction and not an actual ammonia leak.
