How It Works

CAT 100 combines the proven BOS 100® platform with engineered biotechnology to create a next-generation in-situ remedy capable of degrading significantly more contaminant mass per unit dose.

Mechanism of Action:

• Contaminant Binding: Chlorinated solvents adsorb to the activated carbon matrix and contact chemically fused zero-valent iron (ZVI)
• Electron Pump: Complex carbohydrates and peptides degrade slowly, generating electrons
• Catalytic Reaction: Electrons are transferred through the carbon-iron matrix to the electrostatically bound contaminant, where it is degraded
• Iron Conservation: Unlike conventional ZVI, iron is not significantly or rapidly consumed because of electron generation and shuttling
• Iron Surface Area: The manufacturing process creates a massive iron surface dispersed throughout the AC, allowing for far greater mass removal per unit of iron

This system promotes both adsorption and catalytic reductive dechlorination, enabling sustained contaminant breakdown with fewer injections and better longevity.

Common Applications

• CVOC source zones with high mass or DNAPL
• Commingled contaminant plumes (e.g., CVOCs + petroleum)
• Sites with rebound issues post-excavation or SVE
• Regulatory-driven sites requiring aggressive, sustained action

Typical Site Types

• Aerospace and defense facilities
• Industrial solvent handling plants
• Superfund and RCRA corrective action sites
• Rail yards and maintenance depots
• Chlorinated solvent manufacturing and degreasing operations
