2. Industrial Applications & Functional Mechanisms
Water Treatment Systems
Demonstrates exceptional calcium carbonate inhibition (up to 97% at 10ppm concentration) through chelation and crystal distortion mechanisms in cooling towers at 60-80°C operating temperatures.
Detergent Formulations
Enhances surfactant performance by 15-20% through metal ion sequestration in hard water conditions (150-300ppm Ca2+), maintaining pH stability between 9.5-10.5.
3. Operational Guidelines & Safety Protocols
| Application | Dosage Range | Compatibility |
|---|---|---|
| Cooling Water | 5-20ppm | Stable with HEDP/PBTC blends |
| Textile Processing | 0.5-1.2% w/w | Avoid strong oxidizers |
4. Performance Case Studies
Power Plant Cooling System
Reduced calcium sulfate scaling by 89% in 1000MW coal-fired plant recirculating water (cycles of concentration increased from 3.5 to 5.8), achieving ROI within 11 months.
5. Verified Client Implementations
ChemChina Water Solutions Division
Annual consumption: 85 metric tons in reverse osmosis membrane protection applications, maintaining LSI > 2.3 without scaling for 24-month operational cycles.
