* 1 BV (Bed Volume) = 1 m³ solution per m³ resin

Hydraulic characteristics

• Pressure drop: Approximately 12 kPa/m bed depth per 10 m/h at 15°C.
• Backwash: A flow rate of 20 m/h provides approximately 70 % bed expansion at 15°C.

Limits of use

AMBERLITE 252RF H is suitable for industrial uses. For other specific applications such as pharmaceutical, food processing, or potable water, consult Rohm and Haas.
