LEWATIT® AF 5

Summary

Product identification

• Product Name: LEWATIT® AF 5
• Type: Microporous activated carbon like adsorber consisting of spherical beads derived from a styrene-divinylbenzene copolymer.
• Common Description: Neutral
• Functional Group: None
• Matrix: Carbon
• Delivery Form: Black beads
• Edition: 2017-07-03

Applications

LEWATIT® AF 5 is suitable for:

• Water treatment: removal of trace amounts of organic substances such as chlorinated hydrocarbons, MTBE, organic phosphates, amines, pesticides and other metabolites.
• Removal of organics from electroplating process streams.
• Isolation of pharmaceutically active compounds.
• Removal of acetic acid from brine.

Advantages over Activated Carbon

• Regenerable without additional activation (elution usually with hot water or steam).
• Narrow bead size distribution.
• Excellent mechanical stability towards abrasion and attrition due to spherical shape.

Operating limits

• Operating Temperature: max. 300 °C
• Operating pH Range (during exhaustion): 0-14
• Bed Depth (single column): min. 1000 mm
• Max. Pressure Loss (during operation): 250 kPa

Physical and Chemical Properties

• Range of size for >90 vol% of all beads: 0.4-0.8 mm
• Bulk density: 550-650 g/L (+/- 5%)
• Density: approx. 1.34 g/mL
• Stability pH range: 0-14
• Stability temperature range: 1-300 °C
• Surface BET: approx. 1200 m²/g
• Pore volume: approx. 0.15 cm³/g
• Pore diameter: approx. 8 nm

Safety and Handling

• Strong oxidants (e.g., nitric acid) can cause violent reactions.
• Observe the Safety Data Sheet for product description, transport, storage, handling, safety, and ecology.
• Store at temperatures above the freezing point of water, under roof, in dry conditions, and out of 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 under recommended storage conditions.

Disposal

• In the European Community, dispose of ion exchange resins according to the European waste nomenclature.
