Zero-valent iron for in-situ remediation
Reactive iron for permeable reactive barriers and injection programs targeting chlorinated solvents and hexavalent chromium.
Typical failure points
- Abrasive impurities wearing out slurry pumps and injection nozzles
- Loss of reactive iron between production and the injection site
- Batch-to-batch variation that complicates field design
Key specifications
| Parameter | Value |
|---|---|
| Metallic iron (Fe⁰) | ≥ 90–95 % TBC |
| Acid insolubles | < 0.25 % TBC |
| Achievable ORP in test | −400 to −500 mV TBC |
| Sieve range | 100–400 mesh TBC |
- Note: Test conditions for ORP must be stated alongside the value (water matrix, dosage, time).
