When it comes to water treatment, especially in processes that produce drinking water, performance, safety, and reliability aren’t optional. At SMC Global, we are proud to offer HEDP 60%, a high-concentration, high-performance phosphonate anti-scalant that meets the stringent requirements of NSF/ANSI/Kosher/CAN 60 certification. This standard is the benchmark for chemicals used in potable water systems and confirms our product’s safety and quality for critical applications such as reverse osmosis (RO) pre-treatment and distillation processes.
With SMC Global’s blending and manufacturing capabilities lead times are short, and we have better control over product quality, and the confidence that comes with sourcing from a U.S.-based supplier.
HEDP 60% is engineered for exceptional performance across a wide range of systems. It provides excellent scale inhibition, particularly effective against troublesome deposits like calcium carbonate, calcium sulfate, and barium sulfate. In addition to its antiscalant properties, it offers strong corrosion protection for metals such as iron, steel, and copper—making it ideal for both cooling and boiler water systems.
Its effectiveness holds up in high pH environments, which is a significant advantage in systems operating under alkaline conditions. It also functions as a powerful chelating agent, binding metal ions such as Fe²⁺, Cu²⁺, and Zn²⁺ to prevent unwanted precipitation and minimize corrosion. HEDP 60% is thermally stable up to around 250°C, making it a strong choice for high-temperature operations, and it remains stable in the presence of chlorine and other oxidizers commonly used in water treatment.
One of the key benefits of this product is its ability to work synergistically with other water treatment additives, including polymers and zinc salts, allowing for optimized formulations. It also has low reactivity with calcium, which helps reduce the formation of insoluble calcium phosphonates—a challenge often faced with other phosphonates. Compared to alternatives like ATMP or DTPMP, HEDP 60% offers improved biodegradability and environmental compatibility. And because it delivers effective results at lower phosphorus concentrations, it’s well-suited for meeting today’s increasingly strict discharge regulations.
NSF 60 certification requires rigorous third-party testing of production samples to confirm product purity and conformity to potable water drinking standards. This testing is not just a one-time event; it is repeated annually to ensure consistent quality and
compliance over time. These measures provide long-term assurance to our customers who count on safe, stable, and high-performing water treatment solutions.
From a business perspective, HEDP 60% brings a clear set of commercial advantages. Its high concentration reduces the amount of product required to achieve effective treatment, which lowers overall chemical consumption and operational costs. That same concentration also translates to reduced freight costs and smaller storage requirements, improving efficiency across your supply chain.
As a product that supports your Environmental, Social and Governance goals, HEDP 60% helps reduce environmental impact through lower chemical usage and less packaging waste. With ongoing NSF oversight, you also benefit from independent validation of quality, helping support better risk management, purchasing decisions, and regulatory compliance. Combined with SMC Global’s reliable logistics infrastructure and regional inventory availability, you can count on a consistent and scalable supply that keeps your operations running smoothly.
At SMC Global, we believe that effective water treatment goes beyond chemistry, it’s about creating real value across safety, compliance, sustainability, and performance. HEDP 60% is more than a treatment solution, it’s a smarter business decision.
