The Israeli connection to the last mission of Atlantis - the first scientific experiment by Strauss Water and the Fisher Institute tests the purification of drinking water from bacteria and viruses
The technology, developed by the Strauss Water Company, is based on polymers produced in biomedical technology and intended for the purification of drinking water from bacteria and viruses. The information that will be accumulated in space research has implications for water purification on Earth.
The experiment may also be important for the space industry, which wishes to improve the quality of water provided to astronauts, especially during long missions.
On the last day of space shuttle Atlantis' journey, the astronauts successfully drained the reservoir of contaminated water that had accumulated during the mission into space. "Perhaps in the not too distant future the astronauts will not have to empty the polluted water into space, but will be able to use a new Israeli water purification technology," explains Dr. Eran Shankar, head of the Center for Aerospace Medicine Research at the Fisher Institute
Haim Wilder - VP of Research and Development at Strauss Water adds "that the experiment is part of Strauss Water's ongoing effort to develop new technologies and materials that will enable the effective removal of bacteria and viruses from water under extreme conditions. Success in the experiment will be an important milestone."
Ofra Strauss, chairman of the Strauss Group, has long stated that "this is another step by the Strauss Group in order to improve the quality of life of people all over the world through the promise of safe and high-quality water."
The head of the Fisher Institute, Brigadier General Assaf Agmon, sees special importance in Israel's participation in the experiments launched into space, and adds that "Israel has a special status in participating in advanced experiments in the space shuttle and we are excited by the fact that we are participating with our experiments in the last flight of the shuttle era.

I (the first):
Boiling and cooling are problematic not only in space and therefore, as I said, this method is not used on Earth either.
Boiling wastes energy, that's why different methods are developed such as differential-pressure reverse osmosis and other methods.
You can boil the water immediately after filtering it and then cool it, but here I answered myself, the cooling problem in the space is a major problem, so perhaps other methods that do not cause heating are preferred
Why not destroy with ultraviolet?
Maybe the Israeli scientists and science enthusiasts and atheists will also join the Israeli protest and say as a group what is on their hearts tomorrow at 9 in the Bima square?
The link was placed by mistake, there is no connection between the articles, and I also do not upload Scientific American Israel's articles in languages other than Hebrew.
The article is very laconic. There is no explanation of what the plastic is doing - is it filtration or another mechanism. Also what is the special case in space - in common reverse osmosis systems on earth a high pressure is used to facilitate the filtration, so the issue of low gravity is mute. So apart from the name of the company which made the experiment and the fact that it was returned to earth, I have learned nothing of interest here.

Leon, what do you think?
The original article is in Arabic?!!
I am:
For the same reason why you bothered to filter the water you drink today.
Imagine that you had to boil the water before drinking (and also cool it afterwards if you want cold water).
Do you think it's a good idea?
Why not just boil?
