LEWATIT® IN 50

Summary

Product identification

• Product Name: Lewatit® IN 50
• Common Description: inert granulate
• Delivery form: white, translucent

Lewatit® IN 50 is an inert, solid, plastic material supplied in spherical form for application in upflow regenerated ion exchange systems. It is used as a covering and protection layer for upper collection/distribution nozzles, and is specially designed for applications with Lewatit® Reverse W Systems and other packed bed systems. It floats on top of an ion exchange resin bed and is designed to optimize flow performance in a reverse fluidized bed operation. During the downflow service cycle, it acts as an inert spacer material. During upflow compaction and regeneration, it allows dirt and resin fragments to pass to waste while retaining the resin bed and protecting the collector system.

Additional Information

Safety Precautions

• Strong oxidants, e.g. nitric acid, can cause violent reactions if they come into contact with ion exchange resins.
• The safety data sheet must be observed for additional data on product description, transport, storage, handling, safety, and ecology.

Disposal

In the European Community, ion exchange resins must be disposed of according to the European waste nomenclature.

Storage

• Recommended to store ion exchange resins at temperatures above the freezing point of water, under roof, in dry conditions, and without exposure to direct sunlight.
• If resin becomes frozen, allow it to thaw gradually at ambient temperature before handling or use. Do not accelerate the thawing process.
• Packaging stability is limited to 24 months under recommended storage conditions. Use within this timeframe or check packaging condition regularly.
