everyone already recycles water, but you can't make ultrapure water ultrapure again after using it to rinse off chemicals without significant work. "recycling" here means they use the waste water for evaporative cooling. that 2MW of power has to go somewhere and you don't dissipate the waste heat with a big heatsink, you evaporate water with it to get rid of the heat, as with most industrial facilities. we had an actual intel plant manager who actually ran one of intel's fabs on one of the previous threads about this and HNers of course deigned to tell him his business, as usual.
