The global HEDP water treatment market reached $1.2 billion in 2023, with zinc-complexed variants capturing 38% market share (Grand View Research). This amino trimethylene phosphonic acid derivative demonstrates 15-20% higher scale inhibition efficiency compared to conventional ATMP, particularly in high-temperature (80-95°C) industrial systems.
Third-party testing confirms Zn HEDP maintains 92% efficiency at pH 11 versus 78% for standard HEDP. Key parameters:

A: Zn-HEDP is widely used as a corrosion and scale inhibitor in industrial cooling water systems. It effectively stabilizes metal ions like zinc, enhancing treatment efficiency. Its chelation properties also prevent mineral deposits in pipelines.
A: HEDP price depends on raw material costs, production scale, and regional demand. Fluctuations in phosphonic acid and zinc markets often impact pricing. Bulk purchasing or long-term contracts may reduce costs.
A: Polydisperse HEDP contains molecules with varied chain lengths, improving adaptability in complex water chemistries. This diversity enhances its performance in heterogeneous systems. Standard HEDP has a more uniform molecular structure.
A: Zn-HEDP offers synergistic corrosion protection by combining zinc's cathodic inhibition with HEDP's scale prevention. It is environmentally safer than chromate-based inhibitors. Additionally, it works effectively in low-concentration applications.
A: HEDP is generally not recommended for direct potable water treatment due to regulatory limits on phosphonates. However, it is approved in non-potable industrial applications. Always verify local regulations before use.
