Hydraulic Characteristics

Estimated bed expansion and pressure drop figures are provided in the original document, illustrating their dependence on backwash flowrate, service flowrate, and temperature.

• Backwash Expansion Figure 1: Valid for temperatures from 10 – 60°C (50 – 140°F).
• Pressure Drop Figure 2: Valid for temperatures from 10 – 60°C (50 – 140°F). These are expectations at the start of a service run with clean water.

Product Stewardship and Customer Notice

DuPont emphasizes product stewardship, covering safety, health, and environmental aspects. Customers are encouraged to review manufacturing processes and applications to ensure appropriate and intended use. Safety Data Sheets should be consulted before use.

WARNING: Oxidizing agents, such as nitric acid, can attack organic ion exchange resins and may lead to exothermic reactions. Consult knowledgeable sources before using strong oxidizing agents.
