LEWATIT® MonoPlus MP 64

Summary

Product identification

• Product Name: Lewatit® MonoPlus MP 64
• Type: Weakly basic, macroporous anion exchange resin
• Bead Type: Uniform size (monodisperse)
• Matrix: Styrene-divinylbenzene copolymer
• Edition: 2017-07-24

Applications

• Demineralization of water for industrial steam generation, especially in combination with strong basic ion exchangers like Lewatit® MonoPlus M 500 (recommended for Lewatit WS System).
• Treatment of electroplating rinse waters.
• Demineralization of water with high concentrations of humic acids and organic substances to protect strong basic anion exchangers from fouling.

Key Features

• High exchange flow rates during regeneration and loading.
• Excellent utilization of total capacity.
• Low demand for rinse water.
• Homogenous throughput of regenerants, water, and solutions, creating a homogeneous working zone.
• Nearly linear pressure drop gradient, allowing for higher bed depths.
• Chemically and osmotically highly stable beads.
• Optimized kinetics leading to increased operating capacity.

Safety, Disposal, and Storage

• Safety: Strong oxidants (e.g., nitric acid) can cause violent reactions with ion exchange resins. Safety data sheets must be observed.
• Disposal: Ion exchange resins must be disposed of according to European waste nomenclature.
• Storage: Store above freezing point, in dry conditions under roof, away from direct sunlight. If frozen, allow to thaw gradually at ambient temperature before handling or use. Do not accelerate thawing. Packaging stability is limited to 24 months; check packaging condition regularly if stored longer.
