Limits of use

AMBERLITE IR120 Na resin is suitable for industrial uses. For specific applications such as pharmaceutical, food processing, or potable water, consult Rohm and Haas for advice on resin choice and operating conditions.

Hydraulic characteristics

• Bed expansion data as a function of backwash flow rate and water temperature is shown in Figure 1.
• Pressure drop data as a function of service flow rate and water temperature is shown in Figure 2. Pressure drop data are valid at the start of the service run with clear water and a correctly classified bed.
