LEWATIT® MonoPlus M 600

Summary

Product identification

• Product Name: Lewatit® MonoPlus M 600
• Description: Strongly basic, gelular anion exchange resin (type II) with uniform size beads (monodisperse) based on a styrene-divinylbenzene copolymer.
• Functional group: Quaternary amine, type II
• Matrix: Crosslinked polystyrene
• Structure: Gel type beads
• Appearance: White, translucent

Applications

Lewatit® MonoPlus M 600 is designed for all demineralization applications, particularly for waters with moderate concentrations of silica and carbon dioxide. It is especially suitable for:

• Demineralization of water for industrial steam generation, operated with co-current or modern counter-current systems (e.g., Lewatit® WS System, Lewatit® Liftbed System, Lewatit® Rinsebed System).
• Polishing using the Lewatit Multistep System.
• Working mixed beds in combination with Lewatit® MonoPlus S 100 H or Lewatit® MonoPlus S 200.
