Hydraulic Characteristics

Estimated bed expansion and pressure drop as a function of backwash flowrate, temperature, and service flowrate are shown in figures within the original document. These estimates are valid at the start of a service run with clean water and a well-classified bed.

• Backwash: See Figure 1 in the original document.
• Pressure Drop: See Figure 2 in the original document.

Product Stewardship

DuPont emphasizes product stewardship, covering safety, health, and environmental aspects of its products. Customers are encouraged to review their manufacturing processes and applications to ensure safe and intended use.

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