Understanding Sodium HEDP and Polyaspartic Acid Sodium Salt

Sodium HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid) and polyaspartic acid sodium salt represent advanced water treatment chemicals with exceptional scale inhibition properties. These compounds demonstrate 68% better calcium carbonate inhibition compared to traditional phosphonates, according to 2023 IWC Water Chemistry Report. Their molecular structures enable stable chelation of metal ions across pH 3-9.5 ranges, making them ideal for:

Cooling tower systems
RO membrane protection
Industrial cleaning solutions

Technical Superiority in Water Treatment

Third-party testing reveals sodium HEDP achieves 92.4% scale inhibition efficiency at 10ppm concentration, outperforming ATMP (78.1%) and HEDP acid form (85.6%). Key technical parameters:
