LEWATIT® MonoPlus M 800 OH

Summary

Product identification

• Product Name: LEWATIT® MonoPlus MP 800 OH
• Type: Strongly basic, macroporous anion exchange resin (Type I)
• Matrix: Styrene-divinylbenzene copolymer
• Bead Structure: Uniform size (monodisperse)
• Functional Group: Quaternary ammonium
• Delivery Form: OH⁻

Applications

LEWATIT® MonoPlus MP 800 OH is designed for all polishing applications, and is especially suitable for:

• Polishing in combination with Lewatit® MonoPlus SP 112 H or Lewatit® MonoPlus S 108 H (Multistep or conventional mixed bed).
• Condensate polishing in combination with Lewatit® MonoPlus SP 112 H or Lewatit® MonoPlus S 200 H.
• 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).

Key Features

• High chemical and osmotic stability.
• 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, allowing for higher bed depths.
• Good separation of components in mixed bed applications.
• Effective adsorption and desorption of naturally occurring organic substances.
• Particularly low pressure losses compared to standard resins due to high monodispersity and low fines content.
