DESCRIPTION |
Ion exchange resins similar to Jacobi A4 typically refer to strong acid cation exchange resins with gel-type polystyrene-divinylbenzene matrix and sulfonic acid functional groups. These resins are designed for water softening and demineralization applications, offering high exchange capacity and good physical stability.
Water Softening: Removal of hardness ions (calcium and magnesium) from water in industrial and residential applications.
Demineralization: Used in combination with anion resins to produce deionized water for various industrial processes.
Chemical Processing: Catalysis and purification in organic synthesis and chemical manufacturing.
Metal Recovery: Extraction and concentration of valuable metals from process streams and wastewaters.
Sugar and Sweetener Industry: Purification and decolorization in food processing applications.
Type: Strong Acid Cation Exchange Resin
Matrix: Polystyrene-Divinylbenzene (Gel)
Functional Group: Sulfonic Acid (-SO₃H)
Ionic Form As Shipped: Na⁺
Total Exchange Capacity: ≥2.0 eq/L
Moisture Retention: 45-55%
Particle Size Range: 0.3-1.2 mm (≥95%)
Shipping Weight: 800-850 g/L
Specific Gravity: 1.25-1.30 g/ml
Uniformity Coefficient: ≤1.6
Maximum Operating Temperature: 120°C (Na⁺ form)
Note: These parameters are typical for resins in this category. Specific values may vary by manufacturer.
1. Operating Conditions
Service Flow Rate: 10 - 30 BV/h
Operating Temperature: Up to 120°C (Na⁺ form)
pH Range: 0 - 14
Maximum Operating Pressure: 6 bar
2. Regeneration
Regenerant: NaCl (8-12%) for softening; HCl (4-5%) for H⁺ form
Regenerant Dosage: 150-250 g NaCl/L resin or 100-200 g HCl/L resin
Regeneration Flow Rate: 2 - 5 BV/h
Contact Time: 30 - 60 minutes
3. Rinsing
Rinse Flow Rate: 5 - 15 BV/h
Rinse Volume: 2 - 4 Bed Volumes
Rinse Endpoint: Effluent hardness <1 mg/L as CaCO₃ or pH 5-7
4. Performance Indicators
Operating Capacity: 1.7 - 1.9 eq/L
Hardness Leakage: <1 mg/L as CaCO₃
Pressure Drop: 0.7 - 1.5 bar/m bed depth
5. Important Considerations
Oxidant Protection: Free chlorine should be <0.1 mg/L
Iron Fouling: Pre-treatment recommended for high iron concentrations
Suspended Solids: Pre-filtration advised for turbidity >1 NTU
Thermal Protection: Avoid freezing and excessive temperatures
ADVANTAGES |

High Exchange Capacity: Typically ≥2.0 eq/L total exchange capacity for efficient ion removal.
Excellent Physical Stability: Good mechanical strength and resistance to attrition during operation.
Rapid Kinetic Performance: Fast ion exchange rates suitable for various flow conditions.
Wide pH Tolerance: Effective performance across the entire pH range (0-14).
Efficient Regeneration: Can be effectively regenerated with acid or salt solutions.
