Jó kérdés, fogalmam sem volt, de rákerestem: " After each one of several dozen layers of semiconductors are added to the silicon wafer, it must be rinsed, requiring massive amounts of water. A great deal of this water is Ultra Pure Water (UPW), water that is thousands of times purer than drinking water. Water so clean, that it is regarded as an industrial solvent. To make 1,000 gallons of UPW takes roughly 1,400 -1,600 gallons of municipal water1.
... To create an integrated circuit on a 30cm wafer, can require approximately 2,200 gallons of water; including 1,500 gallons of UPW.2"
Szóval ha a fogalmatlanságom nem vezetett teljesen félre, csak a 100-300 procimag tisztításához kell olyan 8000 liter víz.

Amúgy 86%-át újrahasznosítják, de UPW-ként már nem tudják felhasználni, annyira nagy lenne a tisztítási költség, ha jól értem, amit írnak.
