In-situ remediation (ISCO – In-Situ Chemical Oxidation or ISCR – In-Situ Chemical Reduction) is the antithesis of excavation. Instead of removing soil, we deliver the solution directly to the source of the contamination.Using precision injection techniques, we introduce environmentally friendly reagents and nanomaterials into the subsurface, designed to chemically react with pollutants. Whether chlorinated solvents, hydrocarbons, or heavy metals, our products degrade contaminants, transforming them into harmless compounds. The heart of our technology lies in particle size. The use of zero-valent iron (ZVI) and other catalysts at the nanometer or micrometer scale allows for exceptional reactivity: - Capillary Penetration: Our injectable solutions can reach the smallest aquifer fractures and soil pores that excavation could never accurately address. - Targeted reactivity: The reagents specifically attack pollutant molecules, preserving the natural soil matrix. DeltaNova’s approach aligns perfectly with the principles of Green Remediation promoted by the EPA. We use reagents that leave no toxic residues. There is no land consumption, no depletion of natural resources, and the underground ecosystem is restored, not destroyed. Our injection probes take up very little space and can be installed while site operations continue. There’s no need to stop production lines or evacuate facilities. We operate with surgical precision, minimizing disruption to human activities. Eliminando i costi di scavo, trasporto e smaltimento in discarica, i progetti di bonifica in-situ possono generare un risparmio economico significativo, spesso nell’ordine del 30-50% rispetto alle tecniche tradizionali. Inoltre, grazie all’elevata reattività dei nostri prodotti nanotecnologici, i tempi di raggiungimento degli obiettivi di bonifica (CSC/CSR) si riducono drasticamente. With DeltaNova technology, we treated similar sites by injecting a mixture of organic substrates and zero-valent iron. The result? Accelerated solvent degradation in months, not years, without extracting a single drop of water. This approach is supported by rigorous scientific protocols and validated by regulatory bodies.
