Ambersep 900 SO4

Summary

Product identification

AMBERSEP™ 900 SO4 Resin is an industrial-grade strong base anion exchanger.

Description

This is a macroreticular polystyrene type 1 strong base anion exchange resin with quaternary ammonium groups. It is designed for the removal of anions, including weakly dissociated ones like silica. The macroreticular structure provides good resistance to mechanical and osmotic shock. AMBERSEP 900 SO4 Resin is specifically developed for mixed-bed applications and is recommended for uses like condensate polishing due to its mechanical strength and good kinetics, allowing operation at flow rates up to 120 m/h.

Hydraulic Characteristics

Figures 1 and 2 in the original document show bed expansion and pressure drop data, respectively. These figures are related to AMBERSEP™ 900 OH, but the document implies similar behavior for AMBERSEP 900 SO4. Pressure drop data are valid at the start of the service run with clear water and a properly classified bed.

Packaging

• 25 liter bags
