Hydraulic Characteristics

• Pressure drop is estimated as a function of service flowrate at 20°C (68°F) and is valid at the start of the service run with clean water.
• Equations are provided for calculating estimated pressure drop at other water temperatures:
  • P_T = P_20°C / (0.026T_°C + 0.48), where P ≡ bar/m
  • P_T = P_68°F / (0.014T_°F + 0.05), where P ≡ psi/ft

UPW Rinse Properties

• Resins are specially processed and controlled to ensure the purest treated water quality for semiconductor applications.
• Typical rinse curves for resistivity and total organic carbon (TOC) to DTOC = 2 ppb as a function of rinse volume (in bed volumes) are shown in Figure 2.
