This is the new water recycler that NASA is installing in the space station. Typically water is ferried to the station and stored into holding tanks. What this new set up will do is filter water already at the station to save them from shipping 2000 gallons per year. (I can't even fathom the shipping costs)
You may think, I thought they were doing that already, using waste water from showers and the sink?
That's not the waste this set up is recycling. This thing is letting them now add the toilet water to the batch.
I know, I know but squirm all you want it works! I glad someone is thinking out of the box, even if it took the problem of SPACE to finally do it.
