- Anaerobic Bioremediation Reagent



Daramend® anaerobic bioremediation reagent represents a superior biological treatment technology for solid materials impacted by recalcitrant organic compounds. Since the first application in 1996, variations of the technology have been successfully used to treat >10,000,000 tons of soil, sediment and other solid materials.

Daramend treats soils containing chlorinated herbicides and pesticides, organic explosive compounds, and chlorinated VOCs (CVOCs) at many sites throughout the world. The Daramend® technology is uniquely advantageous because: it can often be applied without excavation; its implementation generates no odors or leachate; and it is typically applied at 1 to 3% (soil mass), so it does not result in soil bulking.

  • Improves soil health - tilth and fertility - reduces toxicity
  • Hydrophilic character increases soil water holding
  • Balanced range of nutrients
  • Promotes remediation of most persistent contaminants in soils

In situ chemical reduction (ISCR) is the combination of abiotic chemical reduction, using zero valent iron(ZVI), coupled with anaerobic bioremediation for the effective treatment of chlorinated solvents, pesticides, and energetics. Physical, chemical, and biological processes combine to create an extremely reduced environment that stimulates chemical and microbiological dechlorination of otherwise persistent compounds.
