What processes can be stimulated by injection?
- Aerobic and anaerobic biological oxidation
- Biological reduction
- In situ chemical oxidation (ISCO).
- In situ chemical reduction (ISCR).
- Sorption and desorption processes
- Mobilization and immobilization processes.
- Neutralization processes
The benefits of SPIN® Injection Technology
- Injections in low permeability soils possible (clay, marl, wind-blown silt, etc.)
- Continuous injection between 0 and 75 m depth (depending on lithology)
- Injections of different types of reagents (strong oxidants, zero-valent iron, viscous slurry, etc.)
- The only injection technique with low pressure and continuously adaptable according to the geology encountered
- More homogeneous dispersion by adjusting the injection parameters based on soil texture
- Substantial injection flow rates and volumes resulting in an optimal radius of influence
- Optimal contact between reagents and contamination for efficient remediation
- No soil compaction and thus less or no undesired fracturing, leakage or blow-out of the products
- Continuous measurement and recording of pressure, injection flow rate and volume during injection
- Transparency towards client and consultancy companies thanks to the registration and reporting of injection volumes, flow rates and pressures
WINNER OF THE "NICOLE Innovation Award"
INJECTIS is a winner of the NICOLE Innovation Award (Network for Industrially Co-ordinated Sustainable Land Management in Europe), an award presented to innovative companies with proven technologies in the field of soil remediation to recognize them for their groundbreaking invention.
What types of pollutants do we treat?
By choosing the right (degradation) process and reagents, most contaminants can be addressed with injections.
- Mineral oil, diesel, gasoline, BTEX
- PAH (polycyclic aromatic hydrocarbons).
- VOC (volatile organic compounds).
- PFAS, PFOS, PFOA
- Dioxane
- COHV (chlorinated ethylenes, ethanes and methanes)
- Heavy metals (Pb, Zn, Cr(VI),…)
- Sulfate, nitrate
- Pesticides
- Phenols
- PCB
- pH adjustment
Advantages over other injection methods?
- Possible injections in soils with little or no permeability (clay, marl, wind-blown silt, etc.)
- Single injection technique with low pressure and continuously adaptable according to the geology encountered
- Continuous screw injection (SPIN®) prevents compaction and fracturing
- Injections at great depths are possible (successful test at 75 m-ns)
- Injections of all types of reagents (strong oxidants, zero-valent iron, viscous slurry, etc.) are possible.
- Optimal contact between reagents and contamination for efficient remediation
- More homogeneous spreading thanks to adjustment based on soil texture
- Continuous measurement and recording of pressure, flow and volume during injection
- Transparency towards client and study office thanks to registration and reporting
