Sodium HEDP: A Key Player in Industrial Water Treatment

Sodium HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid), also known as polyaspartic acid sodium salt, is a high-performance scale and corrosion inhibitor widely used in industrial water systems. With a global market CAGR of 5.8% (2023-2030), this organic phosphonate compound demonstrates exceptional stability in high-temperature and high-hardness environments. Its unique molecular structure allows chelation of metal ions at concentrations as low as 2-10 ppm, making it 40% more efficient than traditional phosphates.

Technical Advantages and Performance Metrics

Third-party testing reveals sodium HEDP's superior technical profile:

Scale inhibition efficiency: 98% at 80°C (calcium carbonate)
Corrosion rate reduction: 0.025 mm/year (carbon steel)
pH stability range: 2.5-12.0
Biodegradability: 78% in 28 days (OECD 301F)

Comparative studies show 30% longer equipment lifespan in systems using sodium HEDP versus alternative inhibitors.
