Grade needed for water flow
WebThe ITRS guideline for TOC is <1.0 ppb. Dissolved Oxygen (DO): DO is measured using an electrochemical cell. Typically, DO levels in modern fabs are less than 5 ppb. Dissolved oxygen is removed from UPW using vacuum degasification in membrane contactor systems. Particulate Matter: Raw water sources have high levels of particulate matter.
