LEWATIT® S 1567

Summary

Product identification

• Product Name: Lewatit® S 1567
• Description: Strongly acidic cation exchange resin with uniform size beads (monodisperse) based on a styrene-divinylbenzene copolymer. Manufactured without the use of solvent. Food grade.
• Functional group: Sulfonic acid
• Matrix: Styrenic
• Structure: Gel
• Appearance: Dark brown
• Common Description: Na⁺
• Delivery form: Uniform size beads

Applications

Lewatit® S 1567 is especially applicable for:

• Softening in special systems with regular disinfection
• Softening of drinking water

The resin offers:

• High exchange flow rates during regeneration and loading
• Good utilization of total capacity
• Low demand for rinse water
• Homogeneous throughput of regenerants, water, and solutions, leading to a homogeneous working zone
• Nearly linear pressure drop gradient, allowing for operation with higher bed depth

Operating limits

• Stability pH range: 0-14
• Storage temperature range: -20 – +40 °C
• Operating temperature: max. 120 °C
• Operating pH range during exhaustion: 5-8
• Bed depth for single column: min. 800 mm
• Max. pressure loss during operation: 200 kPa

Feed water

• Regeneration quantity NaCl co-current: min. 100 g/L resin
• Regeneration quantity NaCl counter-current: min. 70 g/L resin
• NaCl regeneration concentration: approx. 8-12 wt. %

Product water

• Total capacity (delivery form): min. 1.8 eq/L

Electrical

Mechanical / hydraulic

• Uniformity coefficient: max. 1.1
• Mean bead size (d50): 0.60 (+-0.05) mm
• Bulk density for shipment (+/- 5%): 810 g/L
• Density: approx. 1.28 g/mL
• Water retention (delivery form): approx. 44-50 wt. %
• Backwash bed expansion (per m/h at 20°C): 4 %
• Specific pressure loss (at 15°C): 1 kPa*h/m²

• Regeneration contact time: min. 20 minutes
• Slow rinse at regeneration flow rate: min. 2 BV
• Fast rinse at service flow rate: min. 2 BV

Additional Information

• Safety precautions: Strong oxidants, e.g. nitric acid, can cause violent reactions with ion exchange resins.
• Toxicity: Safety data sheet must be observed.
• Disposal: Follow European waste nomenclature.
• Storage: Recommended above freezing point, under roof, dry, without direct sunlight. If frozen, thaw gradually at ambient temperature.
• Packaging: Packaging stability limited to 24 months under recommended storage conditions.
