Hydraulic Characteristics

Estimated bed expansion and pressure drop are provided as a function of backwash flowrate, service flowrate, and temperature. Specific figures and conditions are detailed in the original document.

• Backwash Expansion (Figure 1): Temperature = 10 – 60°C (50 – 140°F)
• Pressure Drop (Figure 2): Temperature = 10 – 60°C (50 – 140°F)

Product Stewardship

DuPont is concerned with the safety, health, and environmental aspects of its products. Users are encouraged to review their manufacturing processes and applications to ensure safe and appropriate use. Safety data sheets should be consulted prior to use.

WARNING: Oxidizing agents such as nitric acid can attack organic ion exchange resins, potentially leading to hazardous reactions. Consult knowledgeable sources before using strong oxidizing agents.

Disclaimer: This extraction may miss figures, footnotes, or revisions. Contractual data must match the OEM PDF revision used on the project.
