HC15™ Zero valent Iron Powder

Product Specifications

Our HC15™ material is proprietary engineered material formulated to enhance reactivity for difficult to remediate contaminants. This premium grade material is produced using an innovative manufacturing process which results in ZVI particles which offer a high density of reactive sites.  This is achieved using both specific particle size classification and combinations of ZVI alloying elements. HC15™ powders are available in a wide range of particle sizes that vary from 8 microns up to 250 micron size.  The batch consistency and product reliability are hallmarks of HC15™.

Though a more premium product than our H200™ and HCA™ product lines, the HC15™ atomized material has been developed to treatment hard to address specific compounds.  Data showing its effectiveness on Carbon Tetrachloride, Trichloropropane and vinyl chloride are just a few compounds where very effective reactivity is achieved.

Used properly, Hepure’s ZVI products reduce chlorinated contaminants, as well as immobilize hazardous metals such as arsenic, chromium or lead. They may be applied for insitu remediation by injection, mixing or other emplacement techniques or used as part of an exsitu process in wastewater treatment processes.

Manufacturing Process

Atomized Iron Powder

In the water atomization process, a stream of molten iron is disintegrated into powder by high pressure water jets. The process uses electric arc furnace technology to melt the selected raw material. The molten metal is poured from the furnace to a ladle, and subsequently to a tundish, from which a controlled stream flows into the atomizing chamber. The powder produced in this fashion is dried, and then annealed in hydrogen to remove oxygen introduced by the atomizing process. Atomized powders are irregular, though rounded, in shape, and have little or no internal porosity.

Frequently Asked Questions

Q: What is the difference between sponge and atomized powders?
A:  Sponge powder is produced from magnetite iron ore that is directly reduced at elevated temperatures to obtain sponge iron. The material is then disintegrated into powder. Sponge iron has a very high surface area and exhibits high green strength. To produce atomized powders, molten steel is atomized into irregular and homogeneous particles which are then annealed.

Q: What are the standard packaging sizes?
A:  Standard packaging sizes are as follows:

• 50 lb. bags
• 500 lb. drums
• 2205 lb. bulk packs
• 5000 lb. bulk packs
