Sodium HEDP: A Multifunctional Water Treatment Solution

Sodium HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid Sodium Salt) serves as a high-efficiency scale and corrosion inhibitor with 89% industrial adoption rate across water treatment sectors. Its unique molecular structure enables chelation of metal ions at concentrations up to 450 ppm, outperforming traditional polyphosphates by 62% in calcium carbonate inhibition. When combined with polyaspartic acid sodium salt formulations, the synergistic effect extends equipment lifespan by 3.2 years on average.

Technical Advantages Over Competing Corrosion Inhibitors

Third-party testing reveals sodium HEDP maintains 98% thermal stability at 200°C compared to ATMP's 72% degradation. The compound demonstrates:

40% lower environmental toxicity than EDTA derivatives
pH tolerance range of 2.5-12.8 (vs. 5.5-8.2 for conventional inhibitors)
0.3 mg/L residual phosphorus levels meeting EU Water Framework Directive standards

FAQS on sodium hedp

Q: What is sodium HEDP used for in industrial applications?

A: Sodium HEDP is a scale and corrosion inhibitor commonly used in water treatment, cooling systems, and boilers to prevent metal oxide deposits and improve efficiency.

Q: How does polyaspartic acid sodium salt differ from sodium HEDP?

A: Polyaspartic acid sodium salt is a biodegradable, eco-friendly alternative for scale inhibition, while sodium HEDP is a phosphonate-based chemical with stronger chelating properties but lower environmental compatibility.

Q: Is sodium of polyaspartic acid safe for marine environments?

A: Yes, sodium of polyaspartic acid is non-toxic and biodegradable, making it suitable for marine applications where environmental regulations restrict traditional inhibitors like sodium HEDP.

Q: Can sodium HEDP be combined with polyaspartic acid sodium salt in treatments?

A: Yes, they can be synergistically used in water treatment systems to enhance scale inhibition while reducing environmental impact through partial replacement of phosphonates.

Q: What industries primarily use sodium HEDP and polyaspartic acid sodium salt?

A: Both are used in water treatment, oilfield operations, and industrial cleaning, with sodium HEDP favored in high-temperature systems and polyaspartic acid preferred in eco-sensitive applications.
