Hydroxyethylidene diphosphonic acid (HEDP) has emerged as a cornerstone in industrial water treatment, corrosion inhibition, and scale prevention. With a global market projected to grow at 5.8% CAGR through 2030, HEDP's versatility stems from its ability to chelate metal ions effectively. The polydisperse nature of HEDP ensures compatibility across pH ranges (2-12), making it indispensable for industries requiring thermal stability up to 220°C.
Polydisperse HEDP variants demonstrate 23% superior scale inhibition compared to monodisperse alternatives in controlled trials. Key technical parameters include:
Product | Price ($/ton) | Active Content | Service Life |
---|---|---|---|
ZN HEDP | 1,450 | 60% | 18-24 months |
ATMP | 1,380 | 50% | 12-15 months |
PBTCA | 1,620 | 55% | 15-18 months |
Tailored HEDP formulations address specific water hardness levels (50-5000 mg/L CaCO3). Our modular approach combines:
A power plant in Texas achieved 37% reduction in boiler blowdown frequency after implementing ZN HEDP. Key metrics pre/post implementation:
Parameter | Before | After |
---|---|---|
Scale Thickness | 2.3 mm | 0.4 mm |
Energy Efficiency | 78% | 84% |
Maintenance Costs | $12,500/mo | $7,200/mo |
Recent advancements include nano-encapsulated HEDP particles showing 3x prolonged release characteristics. Industry 4.0 integration enables predictive dosing systems that reduce chemical consumption by 18-22% while maintaining LSI (Langelier Saturation Index) within ±0.3.
With 98.7% purity levels and ISO 9001:2015 certification, ZN HEDP delivers unmatched performance in extreme conditions. Independent testing confirms 0.02 mm/yr corrosion rates in carbon steel systems – 45% lower than industry averages. Our dedicated technical support team ensures optimal implementation across diverse water treatment scenarios.

A: Zn HEDP is used as a corrosion inhibitor and scale preventer in water treatment systems. It effectively chelates metal ions like calcium and magnesium, improving system efficiency. Its stability in high-temperature and acidic conditions makes it ideal for industrial applications.
A: HEDP price depends on purity levels, packaging, and supplier negotiations. Higher-purity grades for specialized industries (e.g., pharmaceuticals) cost more than industrial-grade variants. Bulk purchases often reduce per-unit costs significantly.
A: Polydisperse HEDP offers a range of molecular weights, enhancing adaptability in complex formulations. This diversity improves performance in mixed-metal ion environments, like cooling towers. It also balances cost and efficacy in large-scale applications.
A: Yes, Zn HEDP outperforms traditional phosphates and sulfites by reducing scale and oxygen corrosion simultaneously. It minimizes sludge formation and extends equipment lifespan. Its environmental compatibility also aligns with modern regulatory standards.
A: Raw material costs (e.g., phosphorus trichloride) and energy prices drive HEDP price changes. Trade policies and regional demand shifts, especially from water treatment sectors, also impact rates. Supply chain disruptions further contribute to volatility.
