Hydraulic Characteristics

• Estimated bed expansion as a function of backwash flowrate and temperature is shown in Figure 1 (Temperature = 10 – 90°C).
• Estimated pressure drop as a function of service flowrate and temperature is shown in Figure 2 (Temperature = 10 – 90°C). These expectations are valid at the start of the service run with clean water.

Product Stewardship

DuPont expresses concern for the safety, health, and environmental impact of its products.

Customer Notice

DuPont encourages customers to review manufacturing processes and applications for health and environmental quality. Consult safety data sheets before use.

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