- Contaminant plumes of strongly persistent contaminants
- Highly adsorptive and reactive composite nanomaterial
- Oxidative and reductive reactions feasible
- Custom-made materials available
- Regeneration of the reactive zone possible
Some persistent contaminants, such as PFOA or MTBE, tend to migrate very long distances in groundwater due to their high mobility, are resistant to biological treatment, and are hardly degradable even by strongly reactive chemicals. Thus, a strong combination of sorption efficiency and treatment reactivity is required to retain and treat these contaminants in situ.
With intrawhite® sorption processes strongly support the degradation of persistent pollutants. We create highly reactive zones in the aquifer, where the pollutants are first accumulated and then successively treated. Our target organic contaminants are MTBE, phenols, PAHs (two and three rings) and halogenated hydrocarbons, such as dichloromethane and chlorobenzenes. Explosive compounds can also be successfully treated.
