LEWATIT® SM 600 KR Cl-FREE

Summary

Product identification

• Product Name: Lewatit® SM 600 KR Cl-frei
• Description: Ready-to-use mixed bed resin comprising strongly acidic gel-type cation and strongly basic (type I) gel-type anion exchange resin.
• Form: Fully regenerated (min. 99% H⁺/min. 95 % OH⁻).
• Composition: 1:1 stoichiometric mixture (other mix ratios available on request).
• Grade: Premium grade, purified to meet nuclear industry specifications (extremely low content of desorbable chloride ions and no organically bound chlorine).
• Series: Lewatit® nuclear resins (Lewatit® KR) known for outstanding mechanical and chemical stability, high osmotic stability, and excellent hydrodynamic properties for high flow rates.
• Particle Size: Narrow particle size distribution with very low fines content (max. 0.1% < 0.315 mm) for low pressure losses.

Applications

Lewatit® SM 600 KR Cl-frei is particularly suitable for:

• Polishing in the primary and secondary sections as a mixed bed component.
• Decontamination of circuits in nuclear reactor plants.
• Treatment of primary coolant, e.g., in pressure water reactors.
• Purification of steam generator blowdown, irrespective of the condition with Levoxin (hydrazine), ethanolamine, or morpholine.
• Removal of activated cleavage or corrosion products, including mechanical filtration of suspended impurities.
