LEWATIT® MonoPlus MP 600

Summary

Product identification

• Product Name: Lewatit® MonoPlus MP 600
• Product Type: Strongly basic, macroporous anion exchange resin (Type II)
• Matrix: Styrene-divinylbenzene copolymer
• Bead Structure: Uniform size (monodisperse), macroporous
• Appearance: Beige, opaque
• Delivery Form: Cl⁻

Applications

Lewatit® MonoPlus MP 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 using co-current or modern counter-current systems (e.g., Lewatit® WS System, Lewatit® Liftbed System, Lewatit® Rinsebed System).
• Polishing using the Lewatit® Multistep System in combination with Lewatit® MonoPlus SP 112 or Lewatit® MonoPlus SP 112 (H).

Key Features

• High chemical and osmotic stability.
• High monodispersity and very low fines content result in particularly low pressure losses.
• Effective adsorption and desorption of naturally occurring organic substances due to its special macroporous structure.
• Excellent regeneration efficiency and high operating capacity.
• High flow rates during regeneration and loading.
• Good utilization of total capacity.
• Low demand for rinse water.
• Homogeneous throughput of regenerants, water, and solutions.
• Virtually linear pressure drop gradient across the entire bed depth.
