LEWATIT® MonoPlus MP 800

Summary

Product identification

Lewatit® MonoPlus MP 800 is a strongly basic, macroporous anion exchange resin (type I) with beads of uniform size (monodisperse) based on a styrene-divinylbenzene copolymer, designed for all demineralization applications.

Key Features

• High flow rates during regeneration and loading
• Good utilization of the total capacity
• Low rinse water requirement
• Homogeneous throughput of regenerants, water and solutions, resulting in a homogeneous operating zone
• Virtually linear pressure drop gradient across the entire bed depth, allowing operation with higher bed depths
• Good separation of the components in mixed bed applications
• Effective adsorption and desorption of naturally occurring organic substances

Applications

• Demineralization of water for industrial steam generation (e.g., Lewatit® WS System, Lewatit® Liftbed System, Lewatit® Rinsebed System)
• Polishing using the Lewatit® Multistep System or a conventional mixed bed arrangement in combination with Lewatit® MonoPlus SP 112 (H)
• Condensate polishing in combination with Lewatit® MonoPlus SP 112 (H)

Additional Information & Regulations

• Safety precautions: Strong oxidants, e.g., nitric acid, can cause violent reactions if they come into contact with ion exchange resins.
• Toxicity: The safety data sheet must be observed.
• Disposal: Ion exchange resins must be disposed of according to the European waste nomenclature within the European Community.
• Storage: Recommended to store at temperatures above the freezing point of water, under roof, in dry conditions, and without direct sunlight. If frozen, allow to thaw gradually at ambient temperature before handling or use.
• Packaging: Packaging stability is limited to 24 months under recommended storage conditions. It is recommended to use the product within this timeframe or to check packaging condition regularly.
