Purification - Description :
Ultrapure
water (also UPW or high-purity water) is water that has been purified to stringent specifications. Ultrapure water is a
commonly used term in the semiconductor industry to emphasize the fact that the
water is treated to the highest levels of purity for all contaminant type, including: organic and inorganic compounds;
dissolved and particulate matter; volatile and non-volatile, reactive and
inert; hydrophilic and hydrophobic; and dissolved gases.
UPW and deionized (DI)
water are not the same. In addition to the fact that UPW has organic particles
and dissolved gases removed, a typical UPW system has three stages: a
pretreatment stage to produce purified water, a primary stage to further purify
the water, and a polishing stage, the most expensive part of the treatment
process.
