H200 Plus

Certifiable 95+% Pure

Successor to most widely used ZVI material

70- 80 micron particles

Product HEPUREs new and improved H200 Plus product line replaces H200 which for years has been the industry standard for Insitu Chemical Reduction (ISCR) . Since entering the environmental remediation market in 1996, H200 has been the most widely used micro- scale fine iron powder in the market. Numerous published articles and technical presentations have demonstrated its success at more than 36 sites across North America. H200 Plus represents a significant improvement which we expect will become the new benchmark for ZVI powders. H200 Plus represents a combination of iron grades formulated to provide superior ZVI reactivity to address specific site conditions. Ongoing development has identified the ability to enhance performance over the original H200 sponge grade. These unique ZVI combinations, representing specific iron grades have a defined specific set of characteristics, allowing Hepure to customize formulations for the specific contaminants of concern at the site. H200 Plus is a proprietary high reactivity zero- valent iron material available exclusively through HEPURESM. It is designed to provide superior, cost- effective performance for most in- situ applications. The specific distribution of iron particles in H200 Plus ensures high initial reactivity combined with a longer reactive life to optimize and maintain reducing conditions in the treatment zone. It has effectively been used to remediate halogenated organic compounds, heavy metals and toxic metalloid contaminants. Typical iron content is 95. 5% . H200 Plus can be provided with customized grain- size distribution to meet site- specific conditions. Typical Powder Characteristics Chemical Analysis
