Achieve Rapid and Cost-Effective Chlorinated Contaminant Treatment through Wide-Area Application and Three Donor (3-D) Release Profile

Product Attributes

• Low-Cost (< $0.40 per pound as applied)
  Less money spent on electron donor material equals more money for other project costs or to the bottom line.
• High Volume, Microemulsion Application
  Increases contact with contaminants and reduces number of injection points required for treatment (saves time and money).
• Enhanced Distribution through Micellar Transport
  Unlike oil products, 3DMe forms micelles which are mobile in groundwater and significantly enhance electron donor distribution after injection.
• Persistent and Long Lasting Hydrogen Source
  Provides free lactic acid, controlled release lactic acid and long release fatty acids for effective hydrogen production for periods up to 5 years.
• Incorporates Proven (HRC®) Technology
  Successfully applied on over 1,000 sites worldwide.

Product

3-D Microemulsion (3DMe)™, a form of HRC Advanced®, is a revolutionary new product offering the most advanced hydrogen releasing technology available - at a price point equal to that of lesser performing simple commodity products. 3DMe is a product designed specifically for the low-cost in-situ treatment of chlorinated solvent based contaminants.

3DMe incorporates the proven Hydrogen Release Compound (HRC®) patented technology in addition to an entirely new and unique patented molecule (patent pending) that is specifically designed to time release a combination of highly efficient electron donors. Additionally, 3DMe was designed with a relatively high hydrophilic/lipophilic balance (HLB), allowing dilute suspensions to be well distributed across contaminant plumes without the high injection costs.

Upon application to the subsurface, 3DMe immediately begins to produce hydrogen and to distribute hydrogen generating compounds to the subsurface through a series of hydration and fermentation reactions. This process provides for an immediate as well as time-release supply of hydrogen to fuel the demands of the anaerobic reductive dechlorination process. Typical longevity for 3DMe is up to 2 years or more on a single injection and up to 4 years or more under optimal conditions.

As with any injectable substrate, effective subsurface distribution is key, thus 3DMe was designed to be applied in concentrated form and in high volume. Concentrated applications are similar to that of standard HRC and involve use and injection of the product straight out of the container. High volume applications are different in that the 3DMe is mixed with water on-site, then injected into the subsurface dramatically increasing the volume and distribution of the material throughout the contaminated aquifer.
