Hydraulic Characteristics
Pressure drop and bed expansion data are presented graphically in Figures 1 and 2, respectively. These figures show data as a function of service flow rate, backwash flow rate, and water temperature. Pressure drop data are valid at the start of the service run with clear water and a correctly classified bed.
Limits of Use
AMBERLITE IR122 Na is suitable for industrial use. For specific applications such as pharmaceutical, food processing, or potable water, consult Rohm and Haas Company for resin selection and operating conditions.
