AmberLite FPA900 Cl

Summary

Product identification

AmberLite™ FPA900UPS Cl Ion Exchange Resin

Description

• Food-grade, Uniform Particle Size, High Capacity, Styrenic, Macroporous, Strong Base Anion Exchange Resin for Cane Sugar Decolorization.
• Specially designed for the decolorization of liquid sugar syrups.
• Uniform particle size, styrenic, macroporous, high capacity, Type I strong base anion resin.
• Offers advantages such as readiness for installation without pre-startup backwashing, less resin lift on backwashing, maximum decolorization efficiency, exceptional physical stability, excellent resistance to osmotic shock, and very good organic fouling resistance.
• Uniform particle size distribution offers better approximation to plug-flow, facilitating potential OPEX savings.
• Can be used as a single component or following acrylic AmberLite™ FPA98 Cl Ion Exchange Resin for highly-colored feed solutions.

Applications

• Cane sugar decolorization
