POTOK IN THE SPACE INDUSTRY
Problem description

In space medicine, there are a number of dangers:

01

Deterioration of the sanitary and microbiological state of the air when people live in hermetically closed spacecraft with an artificial environment

02

The high risk of bacteria and fungi penetrating with cargo delivered to the orbital stations

The slightest deviation from the health standards set forth in SSP 50260, the International Space Station Medical Operations Requirements Document (ISS MORD), can lead to dangerous situations that can make it impossible to continue the flight.

01
Result of using the Potok equipment

Potok ensures microbiological purity and reduces the level of microbial contamination of the air in orbital stations.

In 1995,
the Potok equipment solved the problem of colonies of mold fungi in the Mir orbital space station.
In 2001,
the Potok equipment was modified according to the cosmonauts' requests, delivered to the International Space Station (ISS), and installed in the Russian segment.
In 2009,
the Potok equipment was delivered to the US segment as ordered by NASA: in one week of operation, the unit reduced the level of molds in the air to zero (tenfold contamination excess was previously recorded).

The Potok equipment has gained a good reputation from operating in space and has received the gratitude of both cosmonauts and astronauts.

02
Potok in practice

In the Russian segment of the ISS, a Potok unit has been decontaminating air since 2001 in operating mode 6 hours a day.

Result:
3-fold
decrease of the average level of bacterial contamination
4-fold
reduction of the maximum level of mold fungi contamination
