Hydraulic Characteristics

Estimated bed expansion and pressure drop are dependent on backwash flowrate, service flowrate, and temperature. Figures in the original document illustrate these relationships.

Conditioning and Limits of Use

• Suitable for potable water applications after an initial commissioning rinse of 10 bed volumes of potable water at ambient temperature.
• Operating capacity depends on operating conditions and feedwater conditions.
• Warning: Oxidizing agents can attack organic ion exchange resins. Consult knowledgeable sources before using strong oxidizing agents.
• Regulatory Note: This product may be subject to drinking water application restrictions in some countries; check the application status before use and sale.
